Ok, but I'm thinking it must be theoretically possible to get a reasonably well-defined answer (albeit not easily, of course): If we can measure the relative time dilation between the different spacetime geometries of the Earth's surface and any given star, then presumably if we know (or can...

Back to the rate of time - and ignoring speed of travel for a bit now... as we're using the term spacetime - does this imply that the rate of time is also related to (affected by) the 'size' of the space it is in? Ie: does time move slower in a more expansive bit of the universe compared to a...

Ok... How about this: 2 observers in the first second after the Big Bang, both moving away from each other at enormous speed. Each perceives themselves to be stationary, but thinks of the other as moving away very very fast. What is the relative measurement of a second for each of them, but...

Thanks, Warp - it is precisely that difference that I'd be interested in - so perhaps I can make the question more precise to make this easier(!) - if A were an observer on the edge of the expansion in the first second after the big bang, presumably going ridiculously fast (faster than the...

Or perhaps a more simple question to get the ball rolling - how slow was time in it's first second compared to time on Earth now? A million times slower? A billion?...?

Ok, how can I ask the same question without the false premise? A stopwatch somewhere within the newly existing universe?

Can someone answer this for me please: is it possible to work out how much time has elapsed for a theoretical (and for argument's sake, mass-less) observer at the centre of the big bang whose speed of time then subsequently remained constant (rather than massively speeding up with the rest of...
