The Sky in 350 Billion Years

20:45 Common misunderstanding, light emitted, once emitted will stay travelling at c.
Even if an object would move away at 10x c, once the photon leaves it and has a course that will bring it to us
in x years, it would still travel at c.
The object itself and it's speed have no bearing on the light reaching us, once emitted from the source.
And like said, a speed differential may exceed c, for up to 2c, and even then the object itself does not
have to exceed c.
Let's say we travel at 0.1 c from the Big Bang, and we see an object travel at 0.95 c away from
the center of the Big Bang in the opposite direction, the speed differential would 1.05 c,
but the object itself would still only be at 0.95 c and thus not exceed the speed of light.
But even with this speed differential any light emitted from that source would still reach us,
since we only travel at 0.1 c and once emitted the photon would still travel at c towards us.
