Question about the a "relativistic rocket"
Intro:
If one was to measure the redshifts and distances of all galaxies around earth, they would come to a conclusion that they were in the center of the universe because all the galaxies are "moving away from them" faster as the distance to them increases. However, this would be true for anyone on the universe because the universe is homogeneous and doesn't have a "center". It's like being a surface of a balloon being inflated, and the balloon surface not having a center.
Questions:
If I was in a rocket moving at .9c and moving away from Earth would I:
1) If I measure distances/redshifts towards all galaxies around me, will I have the same observation (about universe expanding equally in all directions).
2) If my event horizon behind me reduces, does it mean that it shifts forward also and that I can "receive new events" from something ahead of me?
3) If I was to take Hubble with me and observe some star that it in direction perpendicular to my direction of motion, would I see that the star is round or "squished" in the direction of my motion?
