Space.com post Aug 30 2009 – Tuora
My view of the arrow of time may be more straightforward, I hope. Time exists ONLY in an expanding universe as an intrinsic part of the whole, the 4-th dimension. Conversely, in a black hole, time stands still, swallowed by the gravity of the black hole.
The Big Bang was the time when time begun, right along with the three-D universe. What triggered the Big Bang nobody knows, and I will stop at this junction. We do have several known facts to corroborate Big Bang event and what has followed since.
1. Background radiation at the temperature 2.725° above absolute zero to fix the beginning of time. http://map.gsfc.nasa.gov/universe/bb_tests_cmb.html
2. Hubble constant, http://www.universetoday.com/2006/08/08 ... -constant/
3. Hubble linear chart of distance (X axis) and velocity (Y axis) indicate the universe expanding at an even rate. That demands presence of force acting throughout universe in the real time of the universe. (Big bang alone, once exploded, would merely let the universe coast expanding along at a constant speed.)

4. Dark Matter and Energy: http://www.space.com/scienceastronomy/0 ... nergy.html
“Astronomers estimate now that out of the total mass-energy budget in the universe, about 74 to 76 percent is dark energy, 20 to 22 percent is dark matter and 4 percent or so is normal matter that makes stars, planets and everything we see. And they know that some "force" is causing galaxies to fly away from one another, operating like antigravity.” Note: 75% of dark energy is the cost of creating time for the 4% of “normal” universe we are trying to decipher from within. Time is expensive, but without time to be, nothing is.
-For the sake of clarity, let us exclude the supernatural influence, which does nothing but super-elevates the answer to the wisdom unknown.
So where is the “deus ex machina”, the magic formula to make Universe be?
-Could it be so simple we cannot conceive of it, assuming it must be complex ?
If it were too complex, involving other inputs to make it work, it would not work for Universe to ever be.
We do know the total energy of the Universe is exactly Zero, and the only way to make it work is to fully account for it. Tune in next time. Tuora.
[The expansion of the universe happens over time. As the distances increase, they are moving in a timelike direction. As such, it makes no sense to talk about time expanding or speeding up.]
As far as we have been able to demonstrate. the speed of light is fixed. For the moving observer, the passage of time does not change; it only changes when observed by someone at a different rate of speed. For the person or object moving at any speed, time for them (or it) passes at the same rate.]
