What was the Big band then if not an explosion?

Question

lol Big Bang aswell, sorry for the typo

Answer 1

it was a big bang

Answer 2

An "explosion" happens inside of something else. As far as science knows right now there was no "thing" before the Big Bang. Also, an explosion has a center but the Big Bang had none.

The Big Bang is still going on today since the space of our universe continues to expand. Because there was no space prior to the Big Bang we say that the Big Bang happened every "where" at once.

Hard concepts to imagine, but until / if we ever know about any "thing" existing before the Big Bang we have no other valid alternatives.

Answer 3

The Big Bang was a rapid expansion of energetic space. Particles formed out of this energetic space while the space itself was continually expanding nearly uniformly at every point in space.

For some reason, the expansion was not 100% uniform - there were clumps (or Hot Pockets - hehe) of energy that formed. I'm glad they did because we are here because of it (the non-uniformity).

Answer 4

It can be imaged that the universe, infact all matter, first started out as and infinately small dot in- well nothing.

In the big bang,  the infinately small dot expanded rapidly and enormously (possibley due to energy being converted to mass)  to form the universe as it is today.

Because the expansion starts from one point then expanded massively from that point equally in every direction, rather like an explosion, it was named the "big bang"

So really all it is is the vast and rapid expansion of mass to form the universe- simple really.... XD

Infact, the big bang is still going on today, we have evidence that the other galaxies are moving away from us due to a thing called red shift of line spectra, but because of the universe now is so large, the relative expasion of the universe is much less than at the very beginning, when the diameter of the universe was only very small, so now is only called expansion rather than a big bang.

Hope this helps and is not too confusing :)

Answer 5

an expansion of "space".

Answer 6

god farted

Answer 7

it wasnt a bang there was not particles for sound to happen, it was just a expansion of the universe.

Answer 8

It was the hot dense state of the universe. If it were an explosion, then we would be on an expanding shell of matter, with the explosion at the center and void outside.

That is *NOT* what we observe and that has NOT ever been a theory of cosmology. No matter which way we look, we see galaxies in all directions and at all distances. The universe is filled with galaxies everywhere, and we don't see any huge void spaces into which the galaxies are expanding. In fact, we observe the universe to be homogeneous: smoothly filled with matter absolutely everywhere in space.

Moreover, the galaxies are not streaming through space. They move a little bit, but for the most part, they are all pretty much where they always have been. Put any thought of galaxies rushing through space away from a central explosion out of your head.

Visualize our own galaxy, the Milky Way, and another galaxy a few million light-years away. They're not really moving relative to each other, but the space between them is stretching. So it looks like they're moving because they're getting farther apart--- but it's really that more real estate is being created between them. In fact, more real estate is being created everywhere, between every pair of galaxies in the universe. Even in the room you're sitting in now, more space is being created every moment. Not so much that there's any way you'd ever notice, even with the most sophisticated scientific equipment, but a teeny tiny bit. Every second, the distance between you and the wall, between you and the Sun, between you and the next galaxy, and between you and the very distant galaxies increases by a certain percentage (about one quintillionth every second).* It's this percentage per second that we denote as the rate of the universal expansion. Notice that it's not a speed, for that would imply that everything is moving through space at the same speed. But we know that it's space itself that is expanding, so the more of it there is between two objects, the more it can spread between them.

It's as if the universe were a giant raisin bread, rising in the oven. As the bread rises (as space expands), the raisins (galaxies) don't actually pass through the bread, making tunnels as they go. They are carried along by the expanding bread between them, remaining more or less stationary all the time, and yet expanding away from each other. The farther two raisins are apart, the more bread there is between them, and so the more rising there is expanding them apart. The only difference is that the raisin bread has edges, but the universe has no edge.

So many billions of years ago, there was very little space in the universe at all, but it was still uniformly filled with galaxies--- or really, the gas and energy that would become the galaxies. So the Big Bang is a really bad name for the hot early universe where there was a very small amount of space available. There was less space, but it was filled uniformly everywhere with mass and energy. And it was hot. And it is directly observationally detectable on a daily basis as the Cosmic Background Radiation.

*Actually, That's a little white lie because on the small scales of the solar system the everyday forces of gravity and electromagnetism overcome expansion. The expansion of space within the room doesn't *really* make the room bigger; it just presses on the walls an ever so tiny bit, with about about as much pressure as a single air molecule exerts on them, and the walls can easily overcome such minuscule pressure so there is no observable effect. Same with everything else within the solar system--- or even the galaxy.

Answer 9

More of a sudden, enormous expansion than an actual bang.

Answer 10

The singularity of the big bang was a point of energy that had a life span of 10-34 second, then it underwent a rapid expansion, it was not an explosion as we understand that word to mean.
