: How do we know we can see the furthest galaxies from us. : They could be moving away from us relatively faster than c:

:

: If A is moving at c/2, and B at c/2 in opposite direction, light from A will never reach B, and vice versa?

: Is there a fault in my logic?

Nothing fault.

Your logic is starting point to come out, at, scientific 'Big-Bang-Black-Hole'-cone- thinking theory.

Your logic is starting point, to see that, what nature-space is.

Good luck.
