Is there a growing empty space in the universe at the point where the big bang originated?

Question

would the singular point where all matter was expelled from be empty and growing since all matter is moving away from it?

and since all matter is moving away wouldnt the empty space be constantly growing?

Answer 1

picture the universe like a balloon, and we live on and are confined to the surface. the big bang was the created of all space (the surface of the balloon). so imagine the balloon blowing up. the point at which the big bang happened is literally everything. the point has expanded into the entire universe.

Answer 2

No.  "Big Bang" is a misnomer.  It was, actually, the "Big Expansion".  All matter in the universe was not blown away from the point of origin, it simply expanded from the point of origin.  Matter is still there, it's just that the distance between objects is increasing (as it is throughout the universe).

Think of a balloon filled with air.  Think of the molecules and atoms of air in the balloon as the objects in our universe.  Now think about moving the balloon from ground level to 35,000 feet.  As the balloon moves upward the air pressure decreases and the balloon expands.  The amount of air molecules and atoms inside the balloon remains constant, but the volume that it occupies increases.  This is analagous to the expansion of the universe.

Answer 3

While there is a vast abyss of deep space known as the WMAP Cold Spot that stretches a billion light-years across and contains virtually nothing, this region does not mark the center of the universe.  No region does.  It has to do with the curvature of space itself and the expansion of the universe.

Imagine a balloon with a bunch of dot marks on it.  If you were tiny enough to stand on any of those dots, you could only view the horizon of the balloon, and the edge of your balloon world would seem the same distance to you no matter which dot you stood on.  But none of those dots are the center of the balloon.

It's kind of like that with space.  No matter where in space you stand (or float), the universe itself seems infinitely vast.  That's because space isn't flat - it's curved.  So as the universe expands away from its primordial state, it expands along curves instead of straight-line trajectories.  In the vast reaches of space, Euclid's geometric system breaks down, which can be very hard to grasp, but also really cool once you learn the fundamentals.

Answer 4

That's a good question.  One of the most surprising things I learned when I read up on cosmology was that there is no "place where the Big Bang happened".  The Big Bang wasn't an explosion that shot matter out into preexisting space, where it filled an empty existing void.  The Big Bang was an expansion of the *entire* universe.  That is, there is nothing outside the universe: not even empty space.  There literally is nothing outside--even vacuum isn't empty; there are currents, vibrations, gravity waves, etc. in it.  There is no WHERE to go outside the universe.  So if you were on the edge of the universe you couldn't take a space ship beyond it.

That means that *everywhere in the universe* is where the Big Bang occurred.  It's a big concept to grasp, but the analogy above about balloons should help: as the balloon fills, the outside of the balloon gets bigger, but it's all still the same skin of the same balloon.

Answer 5

There is no growing empty space in the universe at the point where the big bang originated, there always, boundless, eternity, endless universe.

Forever, and the time big bang, only in a specific position of the universe.

There always exists World People Victory, Forever, Universe, study cosmology, astronomy, strive for hope, kind, mind, imagine, dream, happy, free, light

Answer 6

Matter is not necessarily moving away from it. The universe is expanding in a way that doesn't just add space, it stretches the space we already have equally. It is expanding through a 4th spatial dimension. See the balloon model of the universe for more details.

As for your questions, I have no idea what you're trying to get at.

Answer 7

Suppose you have a balloon, and the universe is on the outer surface of it. Further suppose that the balloon was once infinitely small, so that the surface of the balloon was just a point.

Then when the balloon expands, the universe on the surface expands too. But where is the centre of that universe? There isn't one, it is evenly distributed on the surface of the balloon, and the surface has no centre.

Why does the universe have to have a centre?

An explosion IN space has a centre, but the big bang was an explosion OF space, that's an entirely different beast, one which we know very little about.

Answer 8

The false implicit premise of this question has been corrected over and over again, probably hundreds of times, and it has not done one bit of good. Here goes.

Everywhere in the universe is where the Big Bang happened. There is no privileged position in space, no "ground zero," as there would be for any other sort of explosion. No matter what part of the universe you were in, you'd see the distant galaxies moving away from you as if YOU were already at the center of the Big Bang. It's that way for all observers in the universe, no matter where they are.

Of course, this question will be asked yet again. And of course someone will answer it yet again. But it would be nice if people in general would just learn something for once.
