What did the big bang sound like and how do scientists know if there was a sound?

Answer 1

I does go back to the debate:

If a tree falls in the forest, and nobody is around to hear it, does it make a sound.

Nobody can know for sure if there even was a big bang. It is just a theory.

If no one see this answer does it exist? The big bang it's not just a theory, it's a proven theory.

Answer 2

They don't know with certainty; it is theroy. There is evidence, but no conclusive proof.

What is The Big Bang theory?

A.<=________100km_______B.______100km_________=>.CLet the symbol <= be car traveling with a constant speed of 25 km/hr towards the point A and let => be a car traveling with a constant speed of 25 km/hr towards the point C. And let the distances between A and B, and B and C be equal to 100km.

Now can we conclude from this observation that 4 hours earlier both cars were at point B? Yes, of course, provided that we can be confident that the cars have travelled in a straight line at the same speed over the whole 4 hour period.

Imagine that there are cars traveling in all directions outward from the point B with constant speeds of 25 km/hr, and now they are 100km from point B. Can we say that 4 hours earlier, all of the cars were at point B? Yes, of course we can, given the same assumption as above.

Astronomers have observed that the universe is expanding. All galaxies are moving apart from each other. And they also observe that all galaxies appear to be moving away from us, as if we are at the 'center'. One ironic thing is that no matter where in the universe you want to be to observe the expansion, you could see yourself as being at the 'center'. You would observe the same thing we observe from earth; the distant galaxies are moving straight away from you. When scientists calculated their speeds, accelerations and directions of motion, they got that 13.7 (I don't remember the exact number) billion years earlier they were at a single place.

This strongly suggests that 13.7 billion years ago everything in the universe was in one place. That place (a very small volume, probably not a volumeless point as in Euclidean geometry) must have been hot beyond imagining, and could not sustain any matter as we know it; it was ALL energy. Remember Einstein's insight showing how matter is related to energy? At some point the energy began to expand, and space began expanding along with it. During the expansion the energy began to cool, and some particles began to 'condense' out. It really wasn't a 'bang' or 'explosion' as we think of it in everyday experience. More particles formed, they began to clump together because of gravity, and the rest is history, theoretically speaking of course.

The fact that this is theory is not a failing, slur or weakness of the concept. Theory is the life of science, its driving force. Facts are useful but not all facts are inspiring. Once, the rising and setting of the sun were not understood and they provided mysteries for great thinkers to solve. Not much new on that topic. The 'big bang' gets its contemporary power from its ability to fascinate, frustrate and even anger. That is the stuff out of which useful questions and brilliant research are made. In a very real sense, it is irrelevant whether or not the big bang is 'true'. That people are driven by the concept to think, imagine and search-- that is at the very heart of science.

Answer 3

A sound is compression waves moving through matter, like air, water or even the ground. A noise is generally regarded as random sound vibrations. Since there was more matter in one place (the entire universe) than there ever has been since and more random vibrations than ever since, we could say the big bang was the loudest noise ever.

The name "big bang" was given to the event by Sir Fred Hoyle who did NOT believe the theory and used this name as a joke.

______________

Alternate: It is a misconception that there was a lot of 'matter' present just before and during the big bang. There was initially no matter at all. This is because the energy present (the energy inherent in every particle in the entire universe) was so high that no matter could have existed. It was energy, lots and lots of energy. Unimaginably hot. And there was no space-time as we know it. So when the expansion began, there was only energy which expanded right along with space itself. If waves were moving through the expanding energy field and there surely were, it's not likely that they would be classified as audible by any definition. As the expansion continued and started to cool, various particles began to condense out. The rest is history.

Answer 4

The big bang was a rapid expansion of space and time, not an explosion in a particular location, so there was no sound in the conventional sense. Scientists infer the existence of the big bang through observation of the cosmic microwave background radiation, which is leftover thermal radiation from the early universe.

Answer 5

yes but because it happened in space, no one could have heard it (if we were alive or even thought of lol)

The big bang is really stupid and it needs to go to hell
