Question.509 - a) What is located at the center of the Observable Universe, marked X?b) Can we see galaxy C? Why or why not?c) Remember the Lookback Time. If galaxy B is 9 billion ly (9 Gly) away, how long does it take light to travel from galaxy B to us?d) Which looks younger, galaxy A or galaxy B? Why?e) Which galaxy has the bigger cosmological redshift, A or B?f) What is outside the Observable Universe? Answer only one:nothing more galaxies Big Bang only photons a different universeg) So we are in a Universe with no center and no edge, but it is expanding... and it might be infinite. And it is all space and time and mass and energy, but was born out of nothingness. What do you think about this? Does it seem sensible and natural or do you find it odd and confusing? Can you think of any better explanation for what we see? I would like your answer to be at least five (5) sentences long.
