Thaumaturg says the universe can, by definition - say by convention - have no end. Or limits. Right and wrong at the same time. I suggest he
reconsider, by taking into account that beyond the limit we’ve currently set - 180 billion light years across by 30 billion light years deep - there
is nothing. No empty space. No void. Just nothing. As the universe expands - which it is doing counter-intuitively - the nothing-ness retreats.

I hate the talk about the "Universe" It melts my brain. There’s no way in a universe so big we are the only populated planet it would be foolish
to think so and dam ignorant. [Edited by Don W]
I agree. At first blush. OTOH, if you decide we are talking about life forms such as we’d readily recognize, and not some form of life existing in
quantum’s nearly instantaneous dimensions we can never get into, then there are darn few. The planet has to have enough heat from parent star, it
must have a magnetic shield which in our case is a molten iron and nickel core, and it must have the necessary chemicals in the more or less
“ . . if in all that space there is a planet similar to ours and that the civilization upon there is similar to ours with regards to how they have
evolved them too looking into the stars at night wondering like us.
Using the popular 300 billion galaxies, and 300 billion stars per galaxy, we get 90,000 x 10 to the 12th power. Stars. Then if you assume half of
those stars have planet systems, and half of those have properly situated planets, and half of those have a magnetic shield, then you are still
talking a big number of habitable planets. Carl Sagan added the factors of life evolving into higher forms then another cut for civilization to take
place thereby further reducing the number of instance for beings enough like ourselves to want to communicate.
It is my feeling that the distances are so great that we will not be able to make any contact. No one can deny the real possibility - especially
people like me who hold that life is inevitable in the proper circumstances such as on earth - but I have no ability to conceive how we can cross
“Who made the universe? Surely someone somewhere knows the answers . . “
Well, I formerly thought about the “singularity” like this - all the matter (and space) was compressed into this one place or point, a
singularity, which is made possible by thinking of it as being almost infinitely dense and almost infinitely hot. But I think cosmologists scoff at
that idea. You’ve got to get your head around there was “nothing” in the singularity, and then there was what we see today. Quit looking behind.
