What is Earth's maximum velocity away from the centre of the universe, when our orbit around the sun, the sun's orbit around the galaxy and the movement of the galaxy itself are all in alignment?

Answer 1

There is no center of the universe that we know of. This is explained by the space-time continuum. Our galactic alignment is irrelevant.

Earth's maximum velocity away from the center of the universe, when our orbit around the sun, the sun's orbit around the galaxy, and the movement of the galaxy itself are all in alignment, is approximately 2.1 million kilometers per hour.
