Blowing up the big bang theory. Yes a relative vacuum would form at the center of a massive all encompassing explosion like the big bang.

I am working out a simple proof to show that the big bang never happened.  It comes from Isaac Newton actually.  Newton as everyone is aware defined gravity as a force of course the big bang theory sways in the direction of Einstein's path of least resistance space time model of warped space.  The problem is that Newton's equations actually work.  We can't get anything up in orbit without them. If we start the cosmos out as this concentration of all mass an energy into a single unit that is the size of a golf ball or even fits on top of a pin it gets there because the big bang theory says it has infinite gravity and infinite mass (as infinite as the universe that is) Well then this sphere of singularity then has to behave like an object that possesses gravity.  Even if there is nothing at all in it's environment not even empty space when it goes bang an blows up like a huge bomb it has to go from the state of being at rest to in motion.  The problem is that we know for a fact that massive objects with much gravity  are in a state of motion, internal motion which and behave as if they do exhibit what newton saw as the force of gravity. 
The problem is we now even see that if black holes exist they are active .  That is only part of the proof.  The main part comes from the law of equal and opposite reactions in physics.  If something blows up it actually leaves a vacuum at the center of the explosion that will have one of those equal and opposite reactions.  In the atmosphere you can see that happening in an explosion because the air itself is thrust out from the center of the explosion causing a vacuum to appear till it later rushes back in toward the center.  Well blow up the singularity and suddenly you have a vast amount of mass and energy spewing out form the center immediately leaving a relative vacuum of the assumed singularity stasis  at the center.  So actually the explosion of the big bang would be a lot more messy than one giant eruption.  Taking that and modeling it into the theory it may kill the big bang theory all together.  The reason why goes back to how and why the entire universe, all mass, energy and space should be concentrated into The smallest possible unit of space time.  If it is gravity that does it then it will have the same equal and opposite reactions you would see if the sun or the earth blew up.

when a star blows up it also should have a feedback reaction, as per equal and opposite reaction as to have a relative vacuum form at the center or near the center .  To go from a state of stasis to one of everything suddenly being in motion in relationship to everything else and you can pretend that space time itself would not start to ripple or sustain the forces of equal and opposite reactions.
