Why is the universe irregular if everything comes from the same place?

Question

According to the Big Bang Theory, all matter in the universe comes from the same place that exploded and it's still expandig at this exact moment.
But if everithing comes form that place, the result of that explotion should be a sphere, not an irregular mass that is the actual universe; because nothing whould make an action to modify that formation.

Answer 1

this is actually a common misconception about the big bang. space-time itself seems to have originated in the big bang.

the universe does not exist in empty space-time.

the big bang was the whole universe, and everywhere in the universe was once the big bang.

Answer 2

You really have a common but completely wrong misunderstanding about the big bang. The big bang is NOT an explosion of matter outward from a center point. It is an expansion of space itself. In fact according to the Big Bang model THERE IS NO CENTER. The universe is roughly homogenious, on the largest scales one point in space looks pretty much just like any other. Space/Time are derived properties of the Universe. Not something the universe is embedded in. It is also a misconception that the Big Bang model states that entire universe began at a single point. There are actually two big bang models a finite one and an infinite one and only the finite model starts out as a point. In the infinite model the universe is always infinite but because of the rapid expansion, our observable region (plus a great deal more ) began as a point.

Answer 3

Space is what separated masses measure. You might think at first that the amount of space between two masses determines the amount of gravitational potential energy between them, but in fact it's the other way around. And it always has been.

The big bang happened because random quantum fluctuations caused an unusually large surge of energy in a region small enough that an event horizon formed around the it. The energy was then barred from normal thermodynamic dispersion, so two things happened at once. Part of the energy became mass (quarks and leptons) and an equal part became the potential energy between those masses (space).

The inflationary era after the big bang was the sudden increase in space necessary to balance the creation of mass. The universe's expansion is the conversion of kinetic energy (the motion of the galaxies with respect to each other) into more gravitational potential energy (more space between the galaxies).

The irregularities in the distribution of mass from the big bang was probably just turbulence. Just because the condition of maximum entropy is perfect homogeneity doesn't mean that that's what will occur. Just because seven is the most probable result of rolling two six-sided dice doesn't mean you're going to get seven every time, does it?

Answer 4

This is actually one of the big questions in cosmology at the moment, and the only theory that I've heard that gives any sort of explanation is M-Theory.

Two branes collided to spark the Big Bang, and they continue to collide to this day. Since the branes aren't completely uniform, matter was scattered into the universe in clumps rather than even distribution.

Answer 5

some do, some do not. there are a decision of theories provided as an reason behind the existence of the universe, as yet another to theism. i in my opinion prefer to take the clinical impartial position of "we do not recognize yet". Atheism has no longer something to do with the position you've faith the universe got here from, as an theory that's in basic terms in touch with the (non)existence of God. And in simple terms to operate, explosions do not spoil issues, explosion strikes and disperses issues. it ought to spoil total issues (e.g. homes) because it splits them into smaller products yet no longer man or woman debris. the great bang theory would not state that an explosion created the universe by using the undeniable fact that's, it in simple terms moved a large mass of debris right into a larger piece of area and placed distance between them. this is exactly what an explosion does. this isn't coming from a large bang theory supporter, so i'm no longer in simple terms attempting to shield it, your argument hostile to that's mistaken.

Answer 6

Wrong. Particles on the outside would be propelled first. Larger particles may have more momentum than smaller ones. Deflections during and after the explosion would also result in different speeds of the projectiles.

Answer 7

I don't think it spread out evenly in all directions in the big bang. And in areas that got more matter than others, it clumped together due to gravity.

Answer 8

We don't know why matter became "clumpy" after the Big Bang. Heck, we don't know why there's more matter than anti-matter.

Answer 9

entropy.
