I think physicists think the universe has a finite size and shape, albeit expanding. In the roughly two trillion galaxies there are an estimated 10^24 stars (more than a mole) and countless (I use that term loosely) planets.

I have watched this lecture by Lawrence Krauss and it is extremely interesting and understandable to avocational physicists:

It is an hour long and worth every second.

I love what he does with Einsteins equations.

When they actually know, instead of think, I'm all ears.

Werner Heisenberg was pulled over for speeding and the police officer said, "do you know you were going 85 miles per hour?

Werner replied, "dammit, now I don't know where I am."

This is where I have been for sometime now......Clearly the size and scope of the universe is beyond our comprehension. What we see, I suspect is not even beyond our "backyard".
So the thought that any other being/civilization can make the trip outside their own backyard and survive, seems unobtainable, I believe we will never see another being visit earth or anywhere near our system.

Just wait until 2063 when Zephram Cochrane invents warp drive. Things will change pretty fast!

"If" the universe has a specific size and shape I am most interested in what is beyond that!!
