Did the presumed big Bang occur at the center of the Milky way?

Question

If so then the recession velocities are relative to What?

Suppose the big bang was only presumed and some other Phenomena occured what would it be?

Answer 1

To answer your question, No, the Big Bang did not occur at the center of the Milky Way. Now let me try and explain to you part of Big Bang Theory. This may be a little confusing (the first time it was explained to me, it was a very bad explanation and I didn't understand a single word), but I'll try to explain it best I can.

There is no way for us know where the center of the Universe is and where the Big Bang originated. In actuality, there is no real 'center of the Universe' because the whole Universe is expanding, or in other words, no matter where you're at in the Universe you see everything around receding and assume you're the center, but you think to take into consideration the fact that you're also moving and can't ve the center.

The best way to visualize this is to take a balloon and draw some dots on it when it isn't blown up yet. (Remember that this isn't a perfect analogy, but it works). Each of these dots represent a galaxy or a star or just some random point in space. As you blow up the balloon, the surface starts to expand (representing the expansion of the Universe). From your perspective of blowing up the balloon you can see that all of the dots are moving away from each other and none of the dots are the center of expansion. In fact the center is not even on the surface of the balloon, but actually underneath the surface in the center of the three dimensional balloon. But, If you were an ant sitting on the surface of the balloon on one of these dots, your perspective would tell you that everything is moving away from me therefore I must be at the center of everything and am sitting still. Unfortunately, no matter what dot the ant sits on he'll see the same thing, everything receding away from his and he'll conclude that he's at the center.

The same thing is true for us, we see the rest of the universe receding away from us, therefore we piously assume that we must be at the center, at the beginning of everything. But the same would be true if we were in another galaxy, we'd think that other galaxy was the center.

Just like the actual center of expansion of the balloon wasn't even in the same dimension as the surface (the part we could actually see expanding), some people think that it is impossible to see where the Big Bang originated in our dimension because we're stuck on the surface of the 'balloon' (our universe as we know it) and can't see into the dimension where the center is visible.

This is probably very confusing right now, but trust me it actually does make sense. Get a balloon and actually try the experiment so you can see what's happening. Then come back and read this again. Like I said I didn't get it the first time it was explained, but then one day it clicked and now I understand (it doesn't make it any less weird, but I understand).

Answer 2

The Big Bang was more than the mere creation of matter, it was the origin of TIME and SPACE themselves. There is no such thing as "before the big bang", and more confusingly, the Big Bang didn't happen anywhere because the existence of space was the result of the big bang. Hence, the Big Bang happened everywhere in the universe all at once--where you're sitting, the center of the milkyway--everywhere. And space is not static, so the idea of an explicit location even isn't really a valid concept under the relativistic paradigm that begat the Big Bang theory.

Sorry for the confusing answer, but the radical shift in your thinking needed to really understand the Big bang will bring you to understand that the question itself is faulty and has no real answer.

Answer 3

The Milky Way is an obscure little galaxy of several hundred million stars. There are billions of galaxies and none of them were the center of the Big Bang. You seem to be spatially challenged. Search "Solar systems" and "Galaxies" to get some perspective.

Answer 4

that big bang you heard was me hitting my head on the top of the doorframe.
