no it isn’t, it’s hanging around the neck of a cat (or was it a dog?)- I saw the documentary “Men in Black” that proves it

It did hang around a cats neck plus the universe is inside an alien marble.

Alan Guth might disagree with this ‘never’ assertion. On the other hand, the speed of light is slowing down as the expansion-caused energy in the vacuum is increasing, so maybe ...

The edges of the observable Universe are now moving away from us considerably faster than the speed of light.

I don't understand this. In theory, if everything started as a singularity at the time of the Big Bang, then how can I have Hubble images on my hard drive of galaxies colliding?

In theory everything started in the singularity and exploded into on a direct path away from everything else at the same speed and trajectory??

Everything should be flying away from everything else and collisions between galaxies should be impossible.

Thanks :)

The edges of the observable Universe are now [emphasis added] moving away from us considerably faster than the speed of light. The remotest galaxies weren't going that fast when their photons were originally emitted circa 10-12 billion years ago. That is what the Hubble is seeing.

Any photons emitted today from those same sources will never reach us in the future.

Remember, it is the fabric of space itself that is stretching apart at an ever accelerating rate. Relativity applies to objects moving through space, not space itself. (Think of it like an ant crawling along the outside of inflating balloon, where the balloon is blowing up faster than the ant can walk.)

Collisions are local (see post 15).

>> Just when you think you know something, you don’t

A controversy about what we didn’t know...

I love the inordinate vacuum of thought... thanks for the reference.

Bump for a reread later.
