What is it about the Big Bang theory that is unbelivable?

Question

If you don't know what the thoery really is please answer someone elses queation.

I said only answer if you have studied the subject and know why it's a theory in the first place.

Answer 1

The fact that many physicists prefer to leave a creator out of the picture while at the same time formulating laws such as "matter cannot be created" while putting forth theories that allow for a singularity with no dimensions to just explode and create the unimaginable quantity of energy and matter in our observable universe.
Not very intuitive, that's for sure.
Albert Einstein was correct:
"Science without religion is lame....."

Answer 2

Big Bang theory essentially is a theory about the evolution of the universe, what happened after it was created. The theory explains how everything we know came to be, it does not talk about the "beginning" of the universe because we have no way of knowing what the "beginning" of the universe is or was. There is a ton of scientific evidence that does support this theory. The expansion of the universe, cosmic microwave background radiation, and even the nature of matter itself shows this evidence.

It is a theory because it is not absolute truth. Theory means that there is lots of evidence to support it, it can be tested (either physically or in simulation), and it is also fallible (it is possible to prove it untrue or inaccurate). Theory is more than just an idea, it is indeed the way science gives its best description of what is happening.

Answer 3

Having all space, time, energy and matter in the universe come spitting out of a single point (with no size or dimension) in space 13.7 Billion years ago can be a little hard to swallow if you believe in the Bible or some other religious book that tells you otherwise, but there is actual scientific evidence to support the admittedly incomplete theory... two guys named Penzias and Wilson were given the Nobel prize in Physics years ago for (accidentally) discovering the cosmic background microwave radiation which supports (some would say 'proves') the theory.
"Superstring theory" attempts to explain the fundamental nature of matter and energy, but it got bogged down some time in the early 90s because the math broke down into five different theories which were equally good at explaining things, but then a few years ago "M" theory came along and sort of united the five different superstring theories, and now it looks like the Big Bang may have been brought about by the collision of two (or more) of these membranes (don't ask me what a membrane is) and that's why matter is not distributed homogeneously throughout the universe, as one would expect with all matter erupting from a single point. Instead we have clumps of matter in galaxies and stars coupled with emmense stretches of total void big enough to fit millions of galaxies in.... no one had a good explanation for it until "M" theory came along, and its still young as theories go. You can measure the importance of a theory by how long its been around. Old theories are pretty much accepted by all scientists as being usefull descriptions of reality. The theory of evolution and the theory of relativity are good examples of old widely accepted theories that are most likely correct.

Answer 4

I don't use the word "unbelievable;" I prefer "unknowable." For example, the singularity source of our universe defies our current understanding of physics. We don't know where it came from.

Plus the idea that before the singularity, there was nothing; that's hard to grasp, but evidence points to it. So what did the singularity appear in? We don't know. That doesn't mean it's not true or knowable, just that we don't know it now.

I think that for some people, the idea that there was nothingness and then something, without the "design" of some supernatural being, is terrifying.

Add: "Theory" doesn't mean a guess; a theory in technical use is a more or less verified or established explanation accounting for known facts or phenomena.

Answer 5

BIG Bang is not mentioned in the text of the theory. The Big Bang is a tag. The TAG comes from an association to the Atomic Age of the TIME. The expansion of the Universe is a story of creation. In the beginning there was nothing. Do you understand, do you understand? Do You comprehend NOTHING? I wrote a book about nothing and still people ask what is NOTHING. How do you get life from Nothing? I will tell you.

Answer 6

I don't think any part of it is all that unbelievable. At first I thought the infinite density part didn't make sense, but then I thought about it and realized it makes perfect sense. No matter how much pressure the inner core particles are at, whenever they go to move in a certain direction, they always have to move at least a little bit, because there will be more force in the direction it is trying to move (if it were being pushed on equally on all sides), so things cannot be perfectly dense (except maybe at absolute 0), but they can get infinitely close. And it makes sense that all matter would be compact like that because of gravity.

Answer 7

Everything science has to offer supports the BB. The universe is expanding. Why would it be expanding? Only explanation is an explosion. The bigger question is when all these big suns go nova and turn into black holes sucking everything back will the universe retract?

In Carl Sagan's book "Contact," he describes an intelligent, universal attempt to suck the universe back into itself. Aliens. Big project, and one the movie chose to ignore.

Yeah, the Big Bang is real, to answer the question.

Answer 8

At the time of the Big Bang all of the mass and energy in the universe was in the form of light. "Let there be light" In a few seconds it had cooled enough for matter to start forming.

We can still see the background radiation from this initial light.

Answer 9

From what I know about BB "theory", it does NOT say that the universe started from a "point". The equations start with a universe already more than 1.6 x 10^-35 meters across. Small, but certainly not a "point".

Before that, our understanding is unclear.

Answer 10

OK Dred, answer this.

1. What exactly went bang?

2. Where did it come from?

3. What do you call the "it" that went bang?

Nothing cannot beget something. Not Adam and Eve. Not Australopithecus. Not "gravitational singularity".

I call my something God. Got a name for yours yet?
