The accepted age of the Universe is 13 billion years give or take. If you were a super space being and hypothetically had spent a large portion of this time sitting next to a black hole then your experience of time, in fact time itself, 'runs' at a slower pace at your location. Does this mean that at this point the Universe is younger? Is the conventional age of the Universe calculated assuming no effects of general relativity on the time calculation? Or am I completely deluded? Any related insight would be great also. Cheers

  • $\begingroup$ The calculation of the Universe age assumes no significant local gravitational fields. I guess, if you stay close to the horizon of some black hole or neutron star, you would perceive less time $\endgroup$ Commented Jun 26, 2016 at 13:18

  • $\begingroup$ Hi Isaac. The question I've linked asks if the age of the universe is observer dependent, which I think is what you're asking. If you have specific questions e.g. about hovering near black holes perhaps you could edit your question to make it clear what exactly you're asking. $\endgroup$ Commented Jun 26, 2016 at 15:20

No, the age of the universe doesn't depend on the observer. What depends on the observer is the "perceived" time that has passed since the Big Bang.

What you are asking is if the conformal time and the age of the universe are the same and the answer is negative as you can see in that link.
