Spiritually, the Earth still is the center of the universe. As far as we know, there is no other life that has been redeemed by the Son of God and so it will remain.
Physically, there is no center, so we can choose any point in the universe a declare “Here is the center”. As one of the posters above declared Calvary the center.
The math gets more complicated, but it can be worked out. What some people choose to do is say “If the math is simpler, then this must be true” ( Occam’s Razor ). But that is just a tool used to make simpler theories the standard theory.
For example: It is true that I drove to the bus stop today at 25 mph. Assuming the earth is the center of the universe and immobile. I could do the math, assuming the Sun is the center and the fixed stars are immoble (I drove at about 67000 mph and got NO SPEEDING TICKET, but then so did the ground I was driving over). If I assume the galaxies are fixed, then I was moving even faster (about 486000 mph).
We use the geocentric computations because the math is so much simpler. In interplanetary flight, we use heliocentric computations. In travel to the stars I assume we will be using galactocentric computations. But there is no universal preferred frame of reference or center to the universe. I could using Portland Oregon as the center of the universe. It is where I was born. But I try not to live in an evan-centric world.
