[__ Science __ ] Old Earth vs. Young Earth

[Elijah7777]

No, I didn't mean that distance traveled isn't more or less, but time isn't more or less at the poles than at the equator.

Yes, correct. Time is the same everywhere on Earth. All of the planet rotates. We are talking about what is a day. The day begins at sunrise. We call a day 24 hours because the planet rotates in connection with it's orbit around the sun. The gravity of the sun, earth and moon all effect each other. This was all set in motion on the fourth day. This confuses a lot of people. This is why Christians talk about fine tuning. Fine-tuning refers to the idea that the universe is precisely calibrated for life, and many Christians see this as evidence of divine design. Chaos theory shows that tiny changes in initial conditions can lead to vastly different outcomes. This highlights how finely tuned the universe must be—if fundamental constants were slightly different, the universe could be drastically altered. This is just as exact and precise as the Justice of God. This is why Jesus had to keep all of the law of God. In Matthew 5:17, He declares, "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them."

 

[Elijah7777]

In the beginning God created the heavens and the earth, billions or trillions or 6,000 years ago.

What is confusing is that day one is 8 billion years day two is 4 billion years, day three is 2 billion years. So day four with the sun and the moon and the stars began one billion years ago. Day five is half a billion. Day six when God created man was 250 million years ago. So God rested 125 million years ago.

 

[Elijah7777]

time isn't more or less at the poles than at the equator.

Yes time is the same everywhere on earth. The only place time would be different is imaginary and does not exist. My question has to do with the very first word in the Bible: Beginning. When and where does the day begin?

In Dubai’s Burj Khalifa, the world’s tallest building, Muslims observing Ramadan experience a unique challenge—because of the building’s height, the sun sets later for those on higher floors. Islamic scholars in Dubai have ruled that people living above the 80th floor should wait two extra minutes before breaking their fast, and those above the 150th floor should wait three extra minutes.

 

[miamited]

The day begins at sunrise.

That's not an accurate explanation. The daylight part of a day begins at sunrise. Our days begin at midnight and the Jewish day begins at evening time. But no matter how a culture considers when, in the rotation of the earth, a day begins, each day for both the Jew and the Gentile is approximately 24 hours. Whether we choose to start the next 24 hour cycle at 6 A.M. or noon or 7 P.M. the next point to start the next day will be approximately 24 hours later.

In Dubai’s Burj Khalifa, the world’s tallest building, Muslims observing Ramadan experience a unique challenge—because of the building’s height, the sun sets later for those on higher floors. Islamic scholars in Dubai have ruled that people living above the 80th floor should wait two extra minutes before breaking their fast, and those above the 150th floor should wait three extra minutes.

And yet the next new day will start at the same time for everyone no matter how high up above the earth's surface they might stand. What you're referencing here is that for a traditional practice to start at a point such as when the sun moves in the sky to where it begins the period of dusk or sunrise, that can be a few minutes different depending on one's position, but that's only because the time to practice the tradition is set upon a visual appearance of the sun in relation to the earth. But none of that changes the length of a day now does it?

You keep bringing up points that have nothing to do with how the length of a day is determined. A day, and you can check this with any planetary study, is the time that it takes a planetary body to make a full rotation upon its axis. Always has been and always will be. Now, there are different references to a day that change with spatial positioning of the heavenly bodies, such as daytime, which generally refers to the part of the day in which there is sunlight in the area where one is. But a day is still one rotation of the earth upon its axis. Always has been and always will.

 

[miamited]

What is confusing is that day one is 8 billion years day two is 4 billion years, day three is 2 billion years. So day four with the sun and the moon and the stars began one billion years ago. Day five is half a billion. Day six when God created man was 250 million years ago. So God rested 125 million years ago.

Yes, and your evidence for that is...? How many mornings and evenings would be contained in an 8 billion year period of the earth?

 

[Elijah7777]

This is the teaching of MIT PhD Gerald Schroeder. It is based on Einsteain theory of how time is relative. At the speed of light there is no time. That is why we can still see the early universe as if it were only a week old.

[Elijah7777]

And yet the next new day will start at the same time for everyone no matter how high up above the earth's surface they might stand.

We are talking about the day starts at sunrise in their culture. There is a two minute difference for sunrise on the ground compared to the top floor of the building. The sun is always rising and the sun is always setting somewhere in the world. The atmosphere bends light through a process called atmospheric refraction. As light passes through layers of air with different densities, it changes speed and direction, causing effects like: Sunrise and sunset shifts – The Sun appears higher than it actually is because light bends as it enters the atmosphere

When you look at the average tempeture it is always 58 degrees year round. The coldest day of the year is always 6 months from the warmest day. There are no surprises. There is only minor wobble effect from the other planets. If it were just the sun, moon and earth everything would be exteamly precise.

They understand the math. When sending a rocket to Mars, scientists must calculate exactly where Mars will be by the time the spacecraft arrives. They’ve even successfully landed on asteroids, proving how precise their calculations need to be.

My son worked on a NASA robot designed to take core samples and send them back to Earth. He even traveled to Washington to help secure funding for the project.

This is why so many people are interested—there’s massive potential to profit if they can obtain rare elements and sell them.

Gerald Schroeder - Articles - Age of the Universe

So this Gerald Schroeder has shown you his evidence that the first day was 8 billion years old and the next day 4 billions years old, etc. You should share it with others so that we don't have to have this ongoing debate about the age of the universe. Could you at least bring forth the evidence that he has shared with you to explain that the days of creation were such long days and described as a great number of years, and yet God's word says that each one consisted of an evening and morning?

We are talking about the day starts at sunrise in their culture.

Well generally our world operates on the wake-up hours of the day beginning somewhere around sunrise. That's great, but it doesn't have anything to say about the length of those days. Even if we agree that modern culture, and likely all cultures since the beginning have awakened and started their days of work and visiting and mixing around with others beginning at sunrise, that doesn't have any bearing whatsoever on the length of those days. You're just saying that modern man has begun their day at sunrise. You'll get no argument from me that most of the world starts their wake up and go out and about beginning at sunrise.

There is a two minute difference for sunrise on the ground compared to the top floor of the building.

So for you, that means that the people on the ground have 2 minute longer or shorter days than the people on the 80th floor. I'd be interested in seeing your calculations on that. Just because people 'see' the sunrise or set at different times during the day based on their altitude over the earth, that has no bearing on the length of a day. I think you're great wisdom is confusing you about what the difference in our seeing the sun 2 or 3 minutes earlier than others in the same area, and hey, it could be 10 or 15 minutes, but it still is a fact that has absolutely no bearing on the discussion and point being made as the length of a day. It merely means that the person on the 80th floor got to see a few more minutes of daylight within the period of that rotation of the earth upon its axis. But the period of the earth's rotation on its axis is the same for everyone on the earth no matter how high they can put themselves over the earth's surface. You're confused and somehow think that this height that someone is above the earth has something to do with the length of a day... it doesn't.

None of the rest of your post addresses the issue of the length of a day upon the earth. But I'm glad that your son was able to work on the robotics that NASA uses to study the other planets, but it has nothing to do with the length of a day upon the earth. My son is an employee of Apple and has worked on some great projects also, but as far as I know, none of his work has addressed the length of a day, any more than the work your son has done.

What you're doing is called obfuscating. Your making long winded and wonderful arguments about things which don't have any bearing on the question that is being discussed here on the matter of the length of a day. But it keeps people reading and soaking up your information, but it still doesn't, any of it, address the length of a day.

As far as people seeing the light of the sun 2 minutes or three minutes earlier, or the rising of the moon or whatever it is that goes on during the day, that is agreed. I agree that, depending on one's altitude over the earth's surface you can have differences in the time of a day that one might consider the sun to rise. That's actually a matter that is based on the curvature of the earth, but not the length of a day.

 

[Elijah7777]

You should share it with others so that we don't have to have this ongoing debate about the age of the universe.

You can read his book for yourself and draw your own conclusion. No one needs me to convince them of anything. For me he gets science to line up with the Bible.

so that we don't have to have this ongoing debate about the age of the universe.

Your missing the point. All the theories are valid from their own perspective. Like the blind men looking at the Elephant with one looking at the tail and the other looking at the trunk.

God's word says that each one consisted of an evening and morning?

Many Hebrew scholars believe the Torah has multiple layers of meaning, often described as 100 levels of understanding or more. One level does not make the others any more or less true.

but it doesn't have anything to say about the length of those days.

We all agree on how long a day is. Also we know that the word in Genesis one is a literal 24 hour day. If we look at the Hebrew. יוֹם (yom) If the word means something more there are additional letters added. Everywhere in the Bible YOM means a 24 hour day. In Psalms where Moses tells us that a day is one thousand years. But the spelling is different and letters are added to YOM in the Hebrew.

I'd be interested in seeing your calculations on that.

The calculations for prayer times at the Burj Khalifa were conducted by Islamic scholars and astronomers, particularly those involved in Sharia law consultation committees. Researchers from Universiti Kebangsaan Malaysia also studied the impact of altitude on prayer times and published findings on how skyscrapers affect religious observances.

The adjustments are based on astronomical principles, considering how altitude changes the apparent position of the Sun. At the Burj Khalifa, prayer times are divided into three zones based on floor levels.

You're just saying that modern man has begun their day at sunrise.

In the Bible you leave your house behind you at day break to go to work. At night you return to your house at sunset to spent the night. So your house is in front of you when the sun is setting.

I think you're great wisdom is confusing

I am just looking at what a day is on Earth. Some place on Earth is sunrise and someplace on earth is sunset. I personally believe this includes the north pole. You can use classic or quantum physics, it really does not matter. I think this does give us more depth in our understanding of a 24 hour day.

When I was growing up the janitor use to adjust the clocks in our class room every day. My dad had a very special watch that was accurate within three minutes. Time was very accurate and precise because he would see up to 32 patients in a day. Two ever 15 minutes. So this could be why he was so exact and precise.

Then atomic clocks came out and time became very acccurate and precise.

but it still is a fact that has absolutely no bearing on the discussion and point being made as the length of a day.

The phenomenon at the Burj Khalifa is more about perceived time, not the fundamental structure of a day itself. The Earth’s rotation dictates that a day remains the same length—it’s just our perspective that shifts due to light refraction and elevation.

It’s a great reminder of how observations can vary, but the underlying constants remain.

 

[Elijah7777]

It merely means that the person on the 80th floor got to see a few more minutes of daylight within the period of that rotation of the earth upon its axis.

They see the same amount of day light, just at a different time. You have to go north or south to see more or less time. My son lived in Anchorage where In winter, near the winter solstice (December 21), daylight shrinks to about 5.5 hours, with sunrise around 10:14 AM and sunset around 3:42 PM. At the North Pole, the winter solstice (around December 21) marks the darkest time of the year. There is no sunlight or even twilight—just continuous darkness that lasts for several months. Exactly! Even during the polar night at the North Pole, when the Sun doesn’t rise for months, there’s still some ambient light.

I am not making a big deal out of a 24 hour day. But if THAT is what people want to do, then lets do it.

as far as I know, none of his work has addressed the length of a day, any more than the work your son has done.

My son worked on nano-resistors for cars. That has more to do with temperature for quality control than time. But nano technology is very small, very exact, and very precise. So I am saying there is a connection. So I am saying that everywhere on earth has a day and a night. Even if it is just twilight at the North Pole for many months. So there is day and night everywhere on this planet. Even if day is very very short. Even if night is very very long.

The beginning of a nuclear chain reaction starts with just a single atom splitting. In the same way the beginning of day at the north pole can be very short and very brief. But still 24 hour days everywhere on this Earth. This is evidence for a 24 hour day that we read about in Genesis. One rotation of the Earth. Even though a day in the beginning of the Earth.

What you're doing is called obfuscating. Your making long winded and wonderful arguments about things which don't have any bearing on the question

Yes you want very brief and THIS IS MY POINT. The very first day on Earth was not 24 hours. The very first day on Earth was closer to 6 hours. So the length of a day is the same everywhere on earth. But the length of TODAY is different from the length of the very first day. Although there is talk about the perfect day in the Bible but that is for a future even with the new heaven and the new earth.

That's actually a matter that is based on the curvature of the earth, but not the length of a day.

Actually for most YEC the first day was 6000 years ago. So 6,000 years ago a day was almost the same length as a day today but not exactly the same as days are getting longer.

Each new day is slightly longer than the previous one due to Earth's rotation gradually slowing down. The length of a day increases by about 1.7 milliseconds per century.

This change is caused by tidal friction—the gravitational interaction between Earth and the Moon. Over millions of years, this effect has stretched Earth's day from around 6 hours (billions of years ago) to the 24-hour cycle we experience today.

Yes, absolutely! Scientists use atomic clocks and astronomical observations to measure even the tiniest variations in Earth's rotation. These clocks are so precise that they can detect changes as small as a few microseconds per day.

Organizations like NASA and the International Earth Rotation and Reference Systems Service (IERS) track these shifts, and when needed, they even add leap seconds to our clocks to keep time aligned with Earth's actual rotation.

It’s incredible how even tiny, imperceptible differences can be accurately measured.

So even if you just look at wobble effect. No two days are the same length. Due to Earth's axial wobble and other factors like tidal forces, core movements, and climate effects, the length of a day is never exactly the same from one day to the next.

Tks for helping me to think this through. I was not even sure where I was going with this.

 

[miamited]

Like the blind men looking at the Elephant with one looking at the tail and the other looking at the trunk.

Have you actually understood that homily? You do understand that all of them were wrong! So I highly doubt that there's anyway

All the theories are valid from their own perspective

is a statement of truth. And certainly the tale of the blind men trying to define something, but being wrong in all their definitions, is 'like' the point that you're trying to make.

Many Hebrew scholars believe the Torah has multiple layers of meaning, often described as 100 levels of understanding or more. One level does not make the others any more or less true.

Hopefully you also, after really reading and comprehending what this statement says, will come to understand that one level does often make other levels untrue. Friend, you're just spouting off pretty worthless philosophical points that aren't generally true either. Is there a god that looks like Buddha? A lot of people understand that there is.

We all agree on how long a day is. Also we know that the word in Genesis one is a literal 24 hour day. If we look at the Hebrew. יוֹם (yom) If the word means something more there are additional letters added. Everywhere in the Bible YOM means a 24 hour day. In Psalms where Moses tells us that a day is one thousand years. But the spelling is different and letters are added to YOM in the Hebrew.

So then why are you arguing against what you claim that we all believe? You wrote: Also we know that the word in Genesis one is a literal 24 hour day. That's all I've been trying to explain from the beginning of this discussion. I'm glad that we can now agree on that point.

The calculations for prayer times at the Burj Khalifa were conducted by Islamic scholars and astronomers, particularly those involved in Sharia law consultation committees. Researchers from Universiti Kebangsaan Malaysia also studied the impact of altitude on prayer times and published findings on how skyscrapers affect religious observances.

You seem to have obviously not understood my question or not read it completely.

So for you, that means that the people on the ground have 2 minute longer or shorter days than the people on the 80th floor. I'd be interested in seeing your calculations on that.

I asked for your calculations showing that people experience longer or shorter days based on this height above the earth issue that makes Muslim calls to prayer a few minutes different. Show me your calculations that a practicing Muslim on the 80th floor of the Burg Kalifa experiences a longer DAY than the man on the ground. That's what I asked for in my question.

In the Bible you leave your house behind you at day break to go to work.

You actually have Scriptural confirmation of that 'fact'. Could you point me to it? I would agree that it is generally true of life in 'biblical times', but I don't think the bible ever addresses the issue. So I'd be interested to see your explanation and Scriptural references to that claim, also.

When I was growing up the janitor use to adjust the clocks in our class room every day. My dad had a very special watch that was accurate within three minutes. Time was very accurate and precise because he would see up to 32 patients in a day. Two ever 15 minutes. So this could be why he was so exact and precise.

Then atomic clocks came out and time became very acccurate and precise.

And that's a great example that proves nothing as to the length of a day. You believe that the janitor of your school was changing the length of the day when he was adjusting the clocks? Really?? I'm not honestly clear on what it is that you're trying to say about your dad's having 32 patients to see as any sort of consideration in determining the length of a day.

Look, as I said before, your responses seem to be unclear and generally just stuff thrown on the wall to obfuscate the matter under discussion. I sit here chuckling that you have this understanding that some janitor adjusting the clocks at school as having anything to do with time or the length of a day.

The phenomenon at the Burj Khalifa is more about perceived time, not the fundamental structure of a day itself.

And when we get to the point in this discussion, if we ever do, discussing how people, individuals 'perceive' time, then we'll take your instruction under advisement. I'm not talking about how humans might perceive something. I'm talking about the facts offered to us by our Creator as to His work in creating this realm in which we live. When He did it and how long it took, based on His testimony to us. That humans living their lives upon this created earth may have different perceptions of time, doesn't even enter into the equation, as far as I can tell.

They see the same amount of day light, just at a different time.

That's not true. The person on the 80th floor will experience two more minutes of daylight in the morning and in the evening because, at his height, the light of the sun will be seen by him two minutes before it reaches the sight of the man on the ground. That's because as you go higher on a spherical structure your distance to the horizon is greater. At his height, he will also be able to see the sun for two minutes longer in the evening than that person on the ground. The person on the 80th floor will 'see' about 4 minutes more daylight than the person on the ground.

My son worked on nano-resistors for cars. That has more to do with temperature for quality control than time. But nano technology is very small, very exact, and very precise. So I am saying there is a connection. So I am saying that everywhere on earth has a day and a night. Even if it is just twilight at the North Pole for many months. So there is day and night everywhere on this planet. Even if day is very very short. Even if night is very very long.

All of which has squat to do with the length of a day.

The very first day on Earth was closer to 6 hours.

So you believe that the first day spoken of in the Genesis account, the earth rotated one full turn in 6 hours.

 

[Elijah7777]

You do understand that all of them were wrong!

You and I were both mistaken, and I appreciate your willingness to acknowledge that. I have no agenda to push; I am a theistic evolutionist, meaning I place faith in both scientific inquiry and divine truth to understand reality. My father was a medical doctor, and when people visit their doctor, they seek the best possible advice—an approach rooted in trusting the scientific method to uncover truth.

I firmly believe that science and the Bible can be fully reconciled. As new discoveries emerge, they enhance our understanding of Scripture rather than diminish it. Yet, some hesitate to let go of their prior, limited interpretations, clinging to old perspectives despite new revelations.

This is the essence of being a Christian—we must discard our old garments if we wish to be clothed in our wedding attire. Our garments must be purified in the Blood of Jesus, allowing us to step forward in faith, renewed and transformed.

 

[Elijah7777]

Is there a god that looks like Buddha?

Is there a god that looks like Moses? I have no problem with religion. Of course people need to be washed and cleansed in the Blood of Jesus. But if we look at "Buddha" there is quite a extensive teaching on Karma. A lot better then the Karma they teach out on the street about how Karen is going to get what is coming to her.

You wrote: Also we know that the word in Genesis one is a literal 24 hour day.

I do not know if anyone has ever looked at a literal 24 hour day as much as I have. This took place 6,000 years ago. Clearly the world we live in began 6,000 years ago. My history book says we went from a food gather to a food producer. The Garden of Eden is clearly a biodiverse ecology.

In Genesis 3:17-19, God says:

"Cursed is the ground because of you; through painful toil you will eat food from it all the days of your life. It will produce thorns and thistles for you, and you will eat the plants of the field. By the sweat of your brow you will eat your food until you return to the ground..."
We all know Adam was the first food producer. He had two sons. One was a food producer and the other took care of the animals in Eden. Science and History helps us to understand the Bible. There are people who are not as smart as a fifth grader and there are people who have a PhD level of understanding.

I asked for your calculations showing that people experience longer or shorter days

I never said that. I said we all experience a different time of day. Based on sun rise and sun set. What I said was that the earth is slowing down, the day is getting longer over time. 12 noon in one part of the world is 12 midnight in another part. WE see this on new years day as the new day begain in each time zone.

I am just going into a very deep understanding of what we all know to be true. I thought I could come up with a revelation of what a day is, but I did not actually. But I think I improved our understanding. The math is very exact and ever precise. Just as the Justice of God is very exact and very precise. This is why Jesus had to go to Calvery.

You actually have Scriptural confirmation of that 'fact'.

I do not think I am allowed to do that. This has to do with the Hasidic teaching. There maybe a ban on what the people who gave us our Bible have to say about the meaning of the Bible. While there isn’t a universally accepted number like 100 levels, Hasidic teachings do stress that the Torah can be understood on many levels, ranging from literal interpretation to mystical revelation.

My High School was 85% Hebrew people. The director and the Principal were Holocaust survivors. Messiamic are honored but that does not seem to extend to me. Messianic *ews believe in Jesus (Yeshua) as the Messiah, while maintaining their *ewish identity and traditions. Their faith blends elements of Judaism and Christianity, recognizing both the Hebrew Bible (Tanakh) and the New Testament (B'rit Hadasha) as sacred texts.

So you believe that the first day spoken of in the Genesis account, the earth rotated one full turn in 6 hours.

The first sunrise on Earth likely occurred around 4.5 billion years ago, when the planet had formed and its atmosphere began to stabilize. As Earth rotated, the Sun's light would have first illuminated the surface, creating the first cycle of day and night.

The first day in the Garden of Eden is described in Genesis 2, when God created the garden and placed Adam there. This took place 6,000 years ago. I beleive the birth of Jesus and the birth of Adam were 6,000 years apart, exactly. That might be called dispesationalism.

I have two wore out copies of the Ryrie Study Bible is strongly associated with dispensationalism. Dr. Charles Ryrie was a well-known theologian who advocated for classic dispensationalism. No one ever told me that there was anything wrong with Ryrie. If you have a problem with that I can not undue what I did.

 

[Elijah7777]

No, I didn't mean that distance traveled isn't more or less, but time isn't more or less at the poles than at the equator.

The problem is there is no equator and there are no poles. The equator and the poles are simply constructs—mathematical conveniences rather than physical entities—then yes, they’re imaginary in the same way lines of latitude or the Prime Meridian are: ideas we project onto a spherical planet to make sense of it.

Hi Elijah7777

And that means what? Regarding the matter of time passage?

 

[Elijah7777]

And that means what? Regarding the matter of time passage?

Sorry if this is too much information, but this subject really interests me.

There Is No North Pole—And Time Isn’t What You Think

What if the North Pole isn’t real? Not in the way we imagine it, anyway. There’s no monument planted at the top of the world—just an ever-shifting spot, roughly two meters wide, that drifts with the Earth’s wobble. The “axis” we speak of? It’s an invisible thread we’ve drawn through a spinning sphere. You can’t touch it, hold it, or pin it down. And time? Time is a ritual we invented to make sense of that motion.

Everywhere on Earth spins. Every location, no matter how still it seems, passes through a full 24-hour cycle. We carve the globe into time zones—twenty-four slices of artificial midnight—but nature doesn’t divide the day that way. It just moves, in a grand, silent rhythm.

In Genesis 1:14, it is written: “God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years.” That’s not a physics equation—it’s a cosmic blueprint. Time wasn’t created as a clock—it was created as a sign.

Think about this: we celebrate New Year’s Eve twenty-four times around the world. The same date, staggered in sequence like a wave of artificial applause. In the northern hemisphere, it's the shortest day of the year—while in the south, it's the longest. Spring and fall mark the balance point, when day and night shake hands in equality.

We chase precision in the sky too. Consider Triton, Neptune’s largest moon, whose orbit is so close to a perfect circle it defies common celestial messiness. And here on Earth, we’ve engineered satellites—like those in geostationary orbit—to mimic that perfection. They hover over the same point on Earth’s equator, rotating in sync, as if standing still in the firmament.

But let’s not mistake symmetry for certainty. None of this is as fixed as we like to believe. It’s all motion and metaphor—held together by story, scripture, and just enough engineering to keep the illusion spinning.

 

[KV-44-v1]

The length of a day increases by about 1.7 milliseconds per century.

Why would this be a linear function, and not an exponential one?? I would expect the 1.7 figure to increase with time. The assumption of a constant rate seems illogical.

 

[Elijah7777]

Why would this be a linear function, and not an exponential one?? I would expect the 1.7 figure to increase with time. The assumption of a constant rate seems illogical.

I thought the word "about" covered that, but I guess my English is not that good.

$$\Delta t = R \cdot t$$ where Δt\Delta t is the change in day length, RR is the rate (e.g. 1.7 ms/century), and tt is time.

This kind of formula is valid within its assumptions But it’s not absolute truth.

The length of an Earth day increases at an average rate of approximately 1.7 milliseconds per century, primarily due to tidal friction caused by the gravitational interaction between Earth and the Moon. This rate, however, is not constant. When the Moon was closer, tidal forces were stronger and Earth’s rotation slowed more rapidly. As the Moon has receded over billions of years, the rate of deceleration has gradually tapered off.

Although this figure is commonly used for modeling convenience, it represents a simplified average. The true rate varies over geologic time, shaped by shifting ocean basins, continental drift, glacial cycles, and deep Earth-Moon system dynamics.

• The Planck length is widely considered the smallest meaningful unit of length in physics.
• It measures about 1.6 × 10⁻³⁵ meters.
• It’s derived from fundamental constants: the speed of light, Planck’s constant, and the gravitational constant.
• Below this scale, quantum fluctuations dominate, and space-time itself becomes “foamy” and unpredictable.

​

 

[miamited]

The length of an Earth day increases at an average rate of approximately 1.7 milliseconds per century,

Which, if that were a constant, would mean that the length of a day has increased by about 60 milliseconds since the first length of day spoken of in the opening of the Genesis account.
