In every direction, distant galaxies are moving away from us, and the farther they

already are, the faster they're moving away. The best estimate right now is that

the speed of retreat increases about 70 km/sec for every 3.26 million light years ...

the number known as the "Hubble Constant".

If our back-of-the-envelope figures are correct, that's something like

0.00000817 mile per hour per billion miles out.

That doesn't seem like much. But at the distance of the farthest objects that have been

observed so far ... let's say 14 billion light years ... that "Hubble speed" becomes

300,613 km per second (186,792 miles per second) .

Do those numbers look familiar at all ? No wonder we can't see anything farther away than that !

Answer2:

The Universe is not expanding. The Hubble Constant indicates the distance from the boundary condition v=where v=c, the high velocity field.

Hubble did not believe the universe is expanding. The universe is not expanding like the big bang, it is excited like an atom. The electrons jump to a higher level and lower their speed. The lower speed is a lower energy state, the max energy is when v=c.


Hubble;s relationship v=HD indicates the distance D from the max energy state, where v = c.


Hubble's Constant is dR/Rdt =c/R =H = 300M/150TT = 2E-18 m/s x31E21 = 62km/s/Megaparsec.
