The discussion centers on the concept of recession velocity in the context of the expanding universe, specifically addressing the misconception that objects receding faster than the speed of light are moving backward in time. Participants clarify that recession velocity does not equate to speed in the traditional sense, emphasizing the importance of understanding metric expansion. The linked thread provides further insights into this topic, reinforcing the distinction between speed and the effects of cosmic expansion.
PREREQUISITESAstronomers, astrophysicists, and students of cosmology seeking to deepen their understanding of the expanding universe and the implications of recession velocity on cosmic observations.
lnsanity said:Question the thing in the region of space that cannot be seen from us because they recede faster than the speed of light would not they go backward in time relative to us since they exceed the speed of light relative to us ? I know we cannot see it but would not it be true ? or I am missing something ?
