"time" is a difficult concept to grasp, because it is solely based on perspective. We measure it, in the more common forms, here on Earth based on
the cycles of rotation and revolutions around the Sun. There are better methods now to calculate "time", but in actuality, the only way you can
measure time on a universal level would be very limited and very direct.
it would have to be something basic, like molecular movement or decay within spatial matter, perhaps. of course, they would all have to be in sync
with each other, the whole damn idea fails. Movement of stars is still taken as a measurement of time, but I believe this is inaccurate. A good way to
measure time may be to pinpoint the distance between the Universe's most extreme borders to the actual starting point of the entire Universe. That
way you would have a number that tells you how far the final reaches of this existence are from the very beginning of that same enclosure of existence
good luck to getting that figure
With that figure, you can calculate how long things have existed as well as how much time passes moment by moment. You can deduce this by applying the
distance number with the rate of its expansion. Logically, if the rate of expansion increases, so will the progression of said time. Ideally, the
Universe's rate of expansion will always remain the same.
It is also thought that powerful influences, such as gravity, can have an effect on the progress of time. I doubt this, mostly because we have not
truly experimented with that idea. I don't see how flying into a black hole will slow things down. It may slow the perception of time down, yes, but
actual time would be mostly unaffected.
I would not take stock in Einstein's theories of the speed of light in relation to time. He was wrong about a space filled with "ether" (which
could very well be dark matter) and he does not practice the true form of physics, which incorporates 5 primary dimensions: length, width, depth,
time/space, and energy. This is why he was unable to successfully create a Unified Field Theory, along with everyone else studying along the lines of
todays generally-accepted principles of modern physics.
Also, I doubt that the speed of light is the absolute limit of all speeds possible. I don't think that travelling at that rate would have any effect
on time, despite the silly watch experiments conducted on Earth and Einstein's relativity theory of going and coming back to earth at that speed. The
perception MAY slow down, yes, but that does not mean the molecular movement of matter has been altered in anyway. Just because you are moving
incredibly fast does not mean that the rate of time is changing, but in fact, only your perspective of it is.
Think: If you left the Earth with a star ship capable of travelling at warp speeds (its coming soon), how in the hell is that going to affect the
billions of people that are still on Earth? It isnt! What does the fact that you travelled so far so fast have to do with the current state of
existence on Earth? NOTHING!!! So you come back after 20 years (or 20 Cosmotron, the unit I just invented for the measurement of Universal Time) and
land and go back to your house. Your spouse is 20 years older, and just about everything has aged because you left 20 years ago. Even if you went 400
light years to Alnilam and made it back to Earth within a period of a month, this should really have no effect on a grand scale to others. He may
*feel* that the trip to Alnilam and back, say about 3 days, was like minutes or seconds. But again, that's only perception of time and not the
observation of its progress. The one does not affect the many in this case, though I have no idea what happens to molecular movement within the human
travelling at that speed. I would assume it would be unchanged as he would be on a craft and not doing it by himself by flapping his arms or whatever
