    Gods Lego, what are the chances?

    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.

    How would shell theorem act in a hollow sphere?

    That makes sense, thanks!

    How would shell theorem act in a hollow sphere?

    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.

    How would shell theorem act in a hollow sphere?

    I only know of the one focused inward.

    Gods Lego, what are the chances?

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

    How would shell theorem act in a hollow sphere?

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

    Gods Lego, what are the chances?

    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 Schrodinger's Cat.

    How would shell theorem act in a hollow sphere?

    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...

    Basic questions about electric charge

    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...

    If the air is 212 degrees F will water boil?

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

    Physics Salary of Physicists: Hear From Experts

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

    The acceleration of the expansion of the known universe

    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.

    Engineering Computer Engineering: Adapting to the Future of Technology

    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.

    The acceleration of the expansion of the known universe

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

    The acceleration of the expansion of the known universe

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