I recently heard about the effects from The Doppler Effects at high relative speeds (significant fractions of c).
For example you will eventually will even get burned/die by the radiation of the CMBR being ao intensly blueshifted while you're approaching the speed of light (relative).
So with some universe and expansion in mind another thought came up and I wonder if anyone could help answer.
Let's say we are now in "that time" when galaxies far away have started to become so redshifted their light will never ever reach us anymore and are out of sight.
We leave our destination in a spacecraft in a very high speed (as high as needed for this thought).*
- Will now eventually new galaxies reappear because the light from the galaxies are getting blueshifted?*
(Of course just some galaxies and not galaxies in all directions.) And others disappear due to some getting redshifted? This is because the relative speed between some objects decrease while some increase? Maybe an obvious answer but I'd love to hear something more about this if it's the case, and even more if it isn't.
Yours Sincerely
