what if the big bang didn`t happen could the universe still look the same?

Question

ok let me explain assume the unvierse didn`t explode and form only 13 billion years ago but formed in some other way.

Could the background radiation "left over" from the big bang actually be reflected radiation from the other side of all the stars that the observer is looking past. Does that make sense ? not quite sure how to form a galactic mirror but it would seem that this could be reflected light and heat from the billions of stars and objects that are in the way rather then left overs from the big bang.

what do you think ? Anyone able to discredit my theory without being rude?

The theory is like this if the edge of space is hotter then the rest of our space could it be that our best telescopes are short sighted and are just picking up blurred images of stars realy far away and the heat reflected from clouds of interstellar dust.

Answer 1

If cosmic background radiation came from stars, then we'd expect to see much more of it coming from the direction of the center of our galaxy. We don't. That was one of the first things that was checked after the radiation was discovered.

If you don't accept the big bang theory, you have to find alternate explanations not just for cosmic background radiation, but also for the redshifting. The redshifting proves that distant galaxies are moving away from us, i.e. the universe is expanding. Considering that gravity would tend to pull everything closer together, it's hard to explain why things would be moving further apart if you don't start with something like a big bang.

Why is it the case that whenever someone asks a question in the ASTRONOMY section we get a load of religious kooks making ridiculously ignorant comments? There is a seperate religion section on answers, people. Please keep your myths and superstition out of the SCIENCE section.

Anyway, to answer the question: Fred Hoyle proposed a "Steady State" alternative theory to the big bang which proffered an infinite universe with replacement matter being spontaneously generated. It has been pretty much consigned to history and discredited, however.

I think the most compelling evidence in support of a finite Universe (and therefore a big bang) is the fact that we can only see stars and galaxies out to approximately 12-13 billion light years (or whatever the Observable Universe distance is). If the Universe was infinite, we would see stars from infinite distances because they would have had an infinite amount of time for their light to reach us.

Answer 3

Your ideas make a bit of sense. But the thing about the cosmic microwave background is that it is so uniformly spread about the observable universe at a certain microwave frequency/wavelength. If it was heat from stars warming up gas and dust clouds the background would be relatively intense near these, and all but non-existent or at least patchy where they did not exist. But it is spread out everywhere, pretty uniform in distribution.

This implies (but does not necessarily prove) that the universe was once rather smaller than it is now, since if it was always about the same size, the background might not have had time to become so evenly distributed unless the universe was very old.

You are also thinking that there is an edge of space. There may not be. Another thing is that galaxies are pretty small in comparison to the known size of the Universe, dust grains in a football stadium.

Actually I think I'm going to have to think about your question a bit more. It's a good one and it will take a better physicist than me to answer it (would not be difficult to find one).

Edit - You might find female physicists on motorcycles, but you won't find physics in the Old Testament. They though pi was three. Cheers

Answer 4

An early theory by Fred Hoyle postulated a continuous accretion universe.
The problem here is that the universe would have to be infinite.
The big bang seems to be the only logical beginning.
It started as a single space-time pulse.
It accelerated to the speed of light.
the imperfections,the quantum effect is what allowed it to evolve into what we see and experience to-day.
The farthest stars probably don't exist any more and this will be the eventual fate of our galaxy and us.
I don't agree but your theory it has lots of merit.

Answer 5

No one knows what the universe was like before the big bang, i am not superstitious enough to believe in god made the earth and everything, According to researches, the big bang helped the universe in expanding.....

Answer 6

the real question is, was it actually a big bang, or did it just sound like that because there was no other noise around to drown it out!? 'karl pilkington'

Answer 7

Big Bang didn't happen. The earth was a disaster at the beginning but God began to create the earth and all the living things o n earth today, according to their kinds.

Answer 8

its really hard to tell i dont think it would be exactly the same, but there could be some similarities. Depending on what actually did happen.

Answer 9

Like some other guys here answered ur questions, its true that Big Bang is only a theory.....Jehovah created evrything that u see now...He created you....from the biggest form of animals to the smallest bacteria in this planet....The whole Universe...If you will read the book of Genesis, you will know...science is a science, scientist as scientist will answer all teh wuestions with certainty,,,but did this question cross ur mind..." How did they know it?"""Please read the bible and know your Creator Jehovah.....
