If the universe is expanding, then what would be the radial velocity of those galaxies?

What is interesting is that expansion is not motion. Galaxies are not moving away from each other. The space inbetween them is expanding. This expansion creates the exact same red shift.

The radius of the hypersphere is expanding. This creates more points in the universe.

How can Space expand?

It's a joke.

Think about it.

It's all maths no reality.
