Why does the earth seem to be at the center of the hubble expansion?

1. Galaxies in every direction are moving away from the Earth according to different Hubble constants.

2. Galaxies in every direction are moving away from the Earth according to the same Hubble constant.

3. Galaxies in every direction are moving toward the Earth according to different Hubble constants.

4. None of these

5. Galaxies in every direction are moving toward the Earth according to the same Hubble constant.

that's my guess I hopes this helps.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
