# Contractions between big bang and gravitational law [duplicate]

If big bang happened then the centre of the universe must be place of big bang.

Let the mass of whole universe be $$M$$ and mass of small planet or any Astro object be $$m$$. Then the Gravitational force between $$M$$ and $$m$$ be given by:- $$lim_{M\to\infty \, m\to0\, r\to\infty} \frac{G_\infty M m}{r^2}\left(1+\left(1+\frac{r}{\delta}\right)\alpha e^\frac{-r}{\delta}\right)$$

Where $$\alpha$$ and $$\delta$$ are constant.

Then according to the gravitational law ,, attraction force on $$M$$ and $$m$$ must be equal. Then the acceleration of $$m$$ will be infinitely high towards $$M$$ as compare to acceleration of $$M$$.

Then by this theory universe instead of expanding must be compressing and the shape of the universe must be sphere "if big bang theory is correct."

I want to know whether I'm Right or not.

• The big bang was an expansion of space itself. – zeta-band May 13 at 19:16
• Please read the answers to Did the Big Bang happen at a point ?. The key point (and not one easily understood) is that the universe has no center. – StephenG May 13 at 19:25
• Every point is a viable center. – ggcg May 13 at 20:27
• "I want to know whether I'm Right or not." Your very first sentence is wrong, and therefore the rest is as well. – G. Smith May 13 at 22:29

It is a misconception that the big bang happened at a point. It did not. In reality, the big bang happened everywhere in the universe at the same time. There is no center of the universe.
