I was watching a show the other day and it claimed the universe had expanded several millions of miles in the fisrt milliseconds of the universe existing. Just simple math tells me that the 'outer' edge of the universe would have to have exceeded the speed of light in order to reach this distance from the original point of expansion.
Now, obviously the show did not address this, but I was wondering how this works in realistic terms.

NASA put a man on the moon in the sixties ...was it ??and they did it using a chemical rocket .
Practically the same thing that kids use in a sky rocket .
The same thing the Chinese used 3000 years ago .
In other areas technology has advanced tremendously , you get a chip in everything from a toilet roll holder to a washing machine but in space flight there has been a dead stop.
Scientists talk about going to the planets and some even talk about going to the stars but we are NEVER going anywhere with a candle stuck up the rear .
I had hoped to see a real space flight before I die
I'm terribly dissapointed .

If so, may we one day no longer see any at all?
Or is there even a chance that one day, new constellations may form due to the stars moving into different "positions" in the night sky?
Incidentally; how fast are the stars moving "apart" from one-another???
