I recently had an odd theory for the big bang. It is probably wrong and has a large amount of 'holes' .

The idea came when I was watching a Evolution vs Creationism . One man on the Creationist side asked an old but still unresolved question.. What was there before the big bang ?

Theory
According to a law in Physics, Every mass attracts other mass's to it. This Attraction force increases with mass but decreases with distance .This attraction is not noticeable for humans but is needed in planetary,moons and satelitte orbit around their respectively larger masses e.g Earth rotating around the sun. This is the basics of a gravitational field.

My theory is that in time (millions to billions of years perhaps) the whatever singular mass is dominant will pull the other masses in its system towards it. Take the solar system.. The sun could attract the planets closer and eventually engulf the planets, thus becoming a larger mass. Now look at the remaining systems in the Milky Way galaxy.Is it not possible that they attract each other or have some path of motion , couldnt they attract each other to create larger masses .Now look at the remaining galaxies. Is it possible that these galaxies have a gravitional pull towards one another (although the distance from galaxy to galaxy could make the process unimaginably slow) . After an unprecedented amount of time (Trillions of years) . Only a few Supermasses are left. These masses of fusion energy would continue to shrink and eventually explode in a way similar to the big bang. This means the big bang as we know it might not have being the first one.

Problems with theory- Most fusion stars eventually die or explode into a supernova releasing energy but seperating the single major mass.
-It's being shown using doppler light effects in telescopes that the universe is still growing so its possible that the theory is far fetched

Oh well might as well talk about it

In relativity, the big bang created space-time, therefore a "before" the big bang doesn't exist. The question itself is nonsensical. It's kinda like how you can't ask what's north of the north pole.

Thats not a crazy idea.

Something very like it was one of several competing theories in astronomy for some decades. The details differed slightly but in essence it was the same.

There was a big bang. We live on one piece of shrapnel from the big bang-namely the Milky Way Galaxy-which like all the other pieces of shrapnel is hurtling into space.

But gravity obviously causes all of the pieces of shrapnel to pull on each other so gravity is a breaking mechanism that obviously must be slowling all of the pieces of shrapnel down.

So one day in the future all of the pieces of shrapnel will grind to a halt- then - they weill start to fall back towards each other- and the big bang will go into reverse (everything will be blue shifted) and we will have the "Big Crunch" when it all collapes back into a little point. And like the cylinder of a diesel engine the compression will cause it all to explode all over again.

SO.. the last Big Bang that kicked off this cycle of expansion must also have been preceded by a big crunch and a previous universe.

This was known as the "Oscillating Universe Theory"- that the universe goes through cycles of expansion and contraction. There are problems with it- for one thing it makes the universe into a perpetual motion machine. The other is if the whole universe were to collapse into one point then why wouldnt the whole thing turn into a black hole?

A few years a pair of astronomers decided to get to the bottom of it and to actually see what of kind of disc breaks the universe has. So they surveyed all the galaxies going back into the depths of the light years to see just how much the universe is decelerating.

What they found was that the universe is NOT declerating, and that its NOT even staying at the same speed, but that the expansion is acclerating. The foot is on the gas pedal and not the brakes! So the oscillating theory is done for, and now we need to find the gas pedal ( ie the dark energy) thats causing this unexpected acceleration in the speed of this shrapnel!

So something like your idea was a serious contender but its been disproven.
