The Number of Galaxies in the Universe

How it's been worked out.

Sooooo, the people sat there counting the galaxies incrementally are out of a job now?

Wow, that's a tough read.

Interesting to see that LaTex is still used to format technical papers.

The could always get work in a parallel universe.

How many Parallel Universes are there?

A lot or an infinite number

How many Galaxies ???? Look up the meaning of a "Googolplex" then do a Googolplex times a Googolplex and you might get close.

And how many parallel Universes ??? same thing applies.

Been to three of the parallel Universes and ran into my self twice.

It is hard for us to imagine something that goes on forever & ever without end
"Multiverse, Other universes" or "Alternate universes."

This thing is big really Big

Well we can go on about this for years and years....Sounds like fun........The big bang, it created all we can see, 15 billion years, that's a long time, but were did that object that exploded and started the big bang come from?...Will there be a big crunch? And start all over again? Some say yes, some say no, and some say it didn't happen that way as matter just keeps popping into being and after a few billion years goes away.

We can only speculate as to what is going on, as all we can see is all we can comment on, until we can look into the subatomic world and see if there are really strings or even smaller stuff making up the stuff we can see we don't know.

There are even some that think that the so called big bang was a local thing, there are other places out there where the big bang hasn't happened yet, and places where the big crunch is just starting, all these places are further out then what our limited detection equipment can see, what if there was a major development in the detectors and all of a sudden we can see out to 100 billion years, what would we see, a ball of stuff or many other balls of stuff, or we just pushed the outer boundary out to 100 billion years.

This is fun, lets see how many can come up with other theory's.

The Four Levels of THE THEORY OF PARALLEL UNIVERSES

Level 1 The idea of Level 1 parallel universes basically says that space is so big that the rules of probability imply that surely, somewhere else out there, are other planets exactly like Earth. In fact, an infinite universe would have infinitely many planets, and on some of them, the events that play out would be virtually identical to those on our own Earth.

My theory is

I bought starter scope and books, not had chance to do much observing, hopefully in next few months will find time. anyone else here use scope.

I have one, but the light pollution around here is a real problem. I await the power cuts that have been forecast for the past year.
