[_ Old Earth _] Is the big bang theory true?

Is the big bang theory true? Is it Biblical?

What do you mean by true? Most cosmologists/astrophysicists appear to believe that the evidence as currently understood supports it. Why should it be biblical? Are the theory of gravity or quantum theory biblical?

I am currently not as well educated in the subject as i would like to be, but i will give it a shot at a decent explanation.

The big bang is actually supported by quite a bit of evidence:

Einstein's general theory of relativity implies that the universe cannot be static; it must be either expanding or contracting.

The more distant a galaxy is, the faster it is receding from us (the Hubble law). This indicates that the universe is expanding. An expanding universe implies that the universe was small and compact in the distant past.

The big bang model predicts that cosmic microwave background (CMB) radiation should appear in all directions, with a blackbody spectrum and temperature about 3 degrees K. We observe an exact blackbody spectrum with a temperature of 2.73 degrees K.

The CMB is even to about one part in 100,000. There should be a slight unevenness to account for the uneven distribution of matter in the universe today. Such unevenness is observed, and at a predicted amount.

The big bang predicts the observed abundances of primordial hydrogen, deuterium, helium, and lithium. No other models have been able to do so.

The big bang predicts that the universe changes through time. Because the speed of light is finite, looking at large distances allows us to look into the past. We see, among other changes, that quasars were more common and stars were bluer when the universe was younger.

Note that most of these points are not simply observations that fit with the theory; the big bang theory predicted them.

I can explain how the big bang predicts these things as well as how we've already tested and confirmed these things if you'd like. You better be great at physics though because its pretty intense science.

There are still a few observations that we have yet to piece together. For example, we do not currently have an understanding as to why the expansion of the universe seems to be speeding up. However, the big bang has enough supporting evidence behind it that it is likely that new discoveries will add to it, not overthrow it. For example, inflationary universe theory proposes that the size of the universe increased exponentially when the universe was a fraction of a second old (Guth 1997). It was proposed to explain why the big bang did not create large numbers of magnetic monopoles. It also accounts for the observed flatness of space, and it predicted quantitatively the pattern of unevenness of the CMB. Inflationary theory is a significant addition to big bang theory, but it is an extension of big bang theory, not a replacement.

Never-the-less we can confirm that space as we see it now is all coming from one spot and that it is currently expanding and all the other little bits that have been predicted.

So the universe began to exist. Anything that begins to exists has a cause. The rule of Cause and Effect requires the cause to be greater than the effect.

Like i said, i am not as educated in the field as I would like to be. I do know another version of the big bang where the universe expands and contracts continuously. But then again, someone will inevitably ask "well how did that get started".

http://www.big-bang-theory.com/[/url]]According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know.

seems like the most plausible incident.

But because we dont really know for sure, it could be anything.

God could have created the universe (through the big bang as we do have evidence for it), it could of been some alien test, it could have been a completely random event, it could have been unknown chemicals creating a rare reaction or anything really. At this point in time we cannot safely make a decent theory as to why the big bang occurred. However, simply because scientists cant explain it now doesnt make the default God's work as it is just as probable and improbable.

I believe God spoke and BANG! It happened!

The "big bang" is simply the noise made when evolutionists slam the door on logic.

 

[Barbarian]

Er, the big bang has nothing whatever to do with evolutionary theory.

Agreed.

Do you agree that, in a physical sense, the rule of cause and effect requires the cause to be greater than, or equal to the effect?

 

[Evointrinsic]

yes, i would agree
