I read in the books that when A.C. is transmitted at high voltage and low current, the loss in form of heat is minimized. The books say that the H = I^2*R*T and hence, the power loss is minimized, if the current I is minimized. What I fail to understand is --- Why not use the formula H = (V^2/R)*T and say that the loss is more when V is more? (exactly the opposite conclusion!)

More precisely, When a step-up transformer increases V and reduces I, what happens to the formula V=I*R ?

In electronics class the instructor surmised that the massive amount of electricity actually burned the air molecules it was using as a conductor and created a vacuum. The air rushing back into the space caused the crackling. This should be true in both the micro and macro events. (Tesla coils etc) Any one?

is gravity some kind of energy produced by mass(assuming mass can be converted into energy)?

weight of photon is zero because it`s speed is equal to that of light and when we put this speed in relativity formula speed the mass comes out to be zero.when light passes through water it`s speed decreases and must develop weight in water acc. to formula of relativity

As we already know, will 2 light rays attract each other by their gravity (E=M*C^2), though its extremly little. But I have read that Einsteins prediction that gravity is not faster than light has now been proven. That would mean that dependend on the distance between the 2 rays the gravitational attraction of the first phtons of the ray can never reach the first photons of the other ray, but all later coming photons ! So the the first photons will not attract each other, while the others do and will join somewhere in the universe. What do you think ? Right or wrong ?

As a kid, when I learned that the earth moves all the time, I used to hop to find out whether I would land at a different spot. The experiment failed every time, and humanity lost another Galileo. The question is: how high should one jump to land on a different spot, and thereby prove that the earth revolves?

What are your views of him, did he build a zero point energy device? a death ray? was 'silenced'?

if you have some good information give me the link,
cheers

When photons pass by a large mass, say a planet, does the planets' gravitational field act on the particles of light and accelerate them to a higher speed much the same way we get the "slingshot effect" with spacecraft?

I know that it is not possible to exceed the speed of light relative to another object. However, I cant help but think, given the vastness of the universe that we are moving at the speed of light relative to 'something' in the universe (be it an atom, a star, etc.).

Is this a rational thought? It sounds like a stupid question to even me, the asker! Im sure that there is a simple answer, though I supose I am wrong, but why?

An answer such as "no mass can move at c m/s" will not do as an explanation.

If I were in a plane at 1000 mps east and another plane 1000 mps west, and we both had atomic clocks, if we compared them afterwards, what will the outcome be? We are moving 2000 mpc relative to each other, what would happen?
