Physics, Astronomy & Cosmology / How does Hawking's radiation helps in figuring out "the theory of everything"?

« on: 06/05/2016 17:57:32 »

I just watched a video where it is said that Hawking's radiation theory is a link between quantum mechanics and general relativity and that it can explain the theory of everything if it is developed further.Can someone be kind enough to tell me how that can happen?
Does Hawking's really hold the key to the lock of all unexplained theories of the universe?

Physics, Astronomy & Cosmology / How do balanced forces cause motion according to Newton's laws?

If you imagine a situation of tug of war played by two teams exerting equal forces,in that case,no team experiences a motion,that is no single team gets pushed out of the border line (I assume you know the tug of war game)
If that is the case here,then how does Newton actually say that balanced forces cause motion ? I mean doesn't that sound instinctually wrong ?

I would be very grateful if someone answers to the point in a way that it makes sense for a high school student.   []

Physics, Astronomy & Cosmology / How is electromagnetic force a long range force ?

« on: 20/04/2016 05:02:53 »

Electromagnetic force operates between charged particles such as proton and electron,If that is the case how can it be classified as long range force that is it can operate over a long distance ? Isn't charged particles at the atomic level(small distance between proton and electron)  which should make electromagnetic force a short range force ?
