Before I say the exact question, this is a inquiry about a hypothetical situation that says the Universe is infinite in both size and age. If possible, I would like a full explanation to what happens to the Universe going beyond the specific question, but I have the question here basically as a reference. I believe that the answer would be A. there would be no concepts of space and time in our understanding of nature, but I am not certain. Additionally, I looked to post this in the questions forum, but there was no forum for astronomy based questions. Thank you in advance. If the Universe were infinite in size and infinite in time (age), A.there would be no concepts of space and time in our understanding of nature. B.one plus one would equal to three. C.energy would not be conserved. D.there would be no night (dark sky) on Earth. E.there would be no day (bright sky) on Earth.
