This question already has an answer here:
We know all galaxies spread out after Big Bang theory.The key idea is that the universe is expanding after that theory. Can we play back the scenes via observable universe (galaxies) and can we calculate the coordinate of big bang point as a fixed reference point in the universe?
Is there a such calculation in literature or claim?
EDIT: After answers I have some questions:
If the distribution of matter in the universe is homogeneous,how should we think the geometry of universe. Is it a sphere ? Does not a line go to endless as we imagine? Is there any idea of the border of observed universe? If the universe is homogeneous and like sphere geometry, can we see the beginning of our baby galaxy while observing in the sky?
I really will appreciate if someone explains what the universe geometry structure is if we have a homogeneous universe after big bang.
