There is a theory that the big bang’s blast caused an outward push, a kind of reverse gravity if you will, of our universe and everything within it.
My question is how could this have happened? If it really is a kind of reverse gravitational push, this implies something we cant quite comprehend with our minds. Because general relativity proves that gravity is caused by heavy massive objects pulling and curving space time around it causing other objects to roll along it’s valley.
So an outward gravitational push would imply that maybe because of the huge energy blast of the big bang the object causing it would become in a negative energy state causing it, according to E=mc2, to have a negative mass and causing this object to make a kind of mountain in 2 dimensional space time setting our universe in motion rolling downwards this hill. And while rolling kind of unfolding in our current universe. Abd so explaining the accelerating expansion of our universe.
Can this be a possibility or am i suggesting something radical here?
