Re: qustions I would like to ask..
If you accept space as infinite then, by definition, there is nothing outside the universe (because the word universe mean everything). So your question is invalid.

Re: qustions I would like to ask..
A more down-to-earth question might be...............
Why is it that, when four of you go out to a restaurant for a meal, and they put you on a table for six, a waiter immediately comes along and clears away the other two place settings?
It is my absolute major hate.

Re: qustions I would like to ask..
It does and it doesn't is one of the current theories.
Scientists tend to use the word infinite as a substitute for a very long timespan. The universe itself is not considered infinite as such, it is currently expanding and at some point in the future it is thought it will start to contract back to the same instant just before the "big Bang", this is known as the "big Bounce". It is thought by some that this is a cycle, i.e. the universe has expanded and contracted before ad infinitum. Another related theory states that based on the relationship between energy and time (i.e. without energy you have no time) time ceases to exist when the universe is in it's contracted state just before a big bang.
Other theories talk about bubble universes that collide and form new ones, you can then throw string theory into the equation, or even M theory if you are so inclined.
It is all related to Quantum theory and is very interesting, the particle accellerator at CERN should give us some more insights. They are currently cooloing it down to 1.8 Kelvin to carry out some experiments of the early universe.

Re: qustions I would like to ask..
As to where all life evolved from, well the current favourite theory is that we all came from clay. That is that an early form of RNA attached itself to clay molecules and began to display very basic forms of adaptation. Once RNA itself began to evolve then the whole process of biological selction became possible.

"Quantum mechanics suggests that after a while the cat is simultaneously alive and dead, in a quantum superposition of coexisting alive and dead states."

Hmmm. Not sure I agree. I am going to track down Dr Cioci, my school Physics master. He knew everything, he'll know. If he's still alive. Or dead. Or in a quantum superposition of coexisting alive and dead.

I've felt alive and dead a few times after a 24 hour drinking session.
