You should watch "Into the Universe" with Steven Hawking. It covers this topic and a bunch of others like aliens and the properties of spacetime.

That makes sense, thanks!

Well, basically, it states that if you have an object (ie earth) then the force of gravity is focused at the center. So, if you are underground, the mass above you does not have any gravitational effect on you.

I only know of the one focused inward.

According to Hawking, there may be universes being born all the time. Some of them survive, and some don't.

Exactly. And what effects would it have on other objects inside the sphere.

All I can say is that we don't know. We can only assume, and this far, the Big Bang has made the most sense to me. The fact is that nobody is right or wrong at this moment. It's like Schrödinger's Cat.

What I understand is this: Shell theorem states that the force of gravity is focused at the center of an object. But, say that there is a large planet with a gravitational force equal to that of earth's. It is perfectly round… and hollow. Since it is hollow, how large would it be to have Earth's...

I don't know the details yet but would it be true that the 'stronger' source of charge you have, the higher the resistance of the insulator must be? Think of electricity as water through a pipe: Ohm's law states that I=V/R or Current=Volts/Resistance If you plug up the hole (adding...

Also, keep in mind that boiling points for liquids change with altitude (though, I assume the question is for sea level).

Actually, the average Canadian now has a higher income than the average American.

I'll be honest and say I like the way you put it better. It's just that "infinitely finite" was the way I was taught (then again, my physics teacher was also the football coach). Still, I wasn't wrong about the theory in concept. I only put it in a weird way.

I don't think it's ever a waste, necessarily. There may still be some things to discover in silicon based computers, but I do agree that the optical computing may be more lucrative, or maybe developing the quantum computer would be a good way to go if you have the dedication.

It means that the balloon grows forever and doesn't stop, hence, infinite.

It's both because Schrödinger's Cat. (nerd jokes)
