Hi Great Ones (!) Just wondering if someone could help me understand something: Time is relative. If our planet orbited close to a black hole where the effect of gravity was very strong we would look out into the night sky and see stars formed and die, possibly in a single night. We would be writing that a Sun sized star has a stable life of hours or days rather than 8-10 billion years. Would we also be writing that the Universe was just a few centuries old? Also, presumably, the effect of gravity in the Universe would be greater the denser it is, therefore time would have passed more slowly in the dense early Universe.. close to the singularity time would hardly move at all (although relative to what I do not know!) So...... how can we possibly claim the Universe is 13.7 billion years old? Relative to what?? Is the Universe 13.7 billion LIGHT years "old"?
