If this singularity was the start of the big bang, do you know how fast it was traveling in space, and in which direction? Would that have an effect on the distribution of the galaxies?

If the universe is expanding, how come we get a blue shift on stars or galaxies?
Shouldn't it all be in the red?

I'm 83 yrs. old and enjoying reading about the unverse.

Hi czycaggg, how you doing?

The problem with the original question is that the big bang theory says that before it there was no "space" therefore the singularity couldn't be travelling anywhere. somewhat paradoxical.

Your right. I've started to read "Wrinkles in Time" bySmoot and Davidson.
I'm learning haha.

Scientists can only predict what was going on in the universe about 3 sec (or 3 min, I'm not sure which) after the big bang. No-one has any real evidence of what the pre-big bang universe was flowing through.
