How do we know we are not at the center of the universe?
Hubble discovered that the galaxies are moving away from us with a velocity proportional to their distance. Every point in the universe is expanding from every other point at a constant rate. There is no expansion from a particular point. Since the universe has no edge – it is unbound – it has no centre.
Where exactly within the universe are we located?
Well, Earth is located in the universe in the Virgo Supercluster of galaxies. A supercluster is a group of galaxies held together by gravity. Within this supercluster we are in a smaller group of galaxies called the Local Group. Earth is in the second largest galaxy of the Local Group – a galaxy called the Milky Way.
Do we know the shape of the universe?
The exact shape is still a matter of debate in physical cosmology, but experimental data from various independent sources (WMAP, BOOMERanG, and Planck for example) confirm that the universe is flat with only a 0.4\% margin of error.

Where is Centre of the universe?
There is no centre of the universe! According to the standard theories of cosmology, the universe started with a “Big Bang” about 14 thousand million years ago and has been expanding ever since. Yet there is no centre to the expansion; it is the same everywhere.
Why does the universe have no center?
There no centre of the universe because there is no edge of the universe. In a finite universe, space is curved so that if you could travel billions of light years in a straight line you would eventually finish back where you started. It is also possible that our universe is infinite.
