If a singularity slows time. How long was the first second after big bang?
No, it is not. It looks different to a remote observer but that's a different story.A second by my watch is different from a second next to a singularity.
Yes, It would have been the time it took light to travel 186000 miles along a spacetime geodesic, assuming there was nothing to get in its way.Are you saying it would be the time it took light (if it had existed) to travel 186000 miles (in which case it would have been a really long second)? Just trying to get this concept right in my head before I launch into more study.
