OK. I'm no physicist, but the formula and the physical evidence somehow don't add up.

Most sources indicate that the photon is "massless" (M=0). A table in Zukov's "Dancing Wu Li Masters", compiled by Lawrence Berkeley Laboratory, adds graviton, electron neutrino and muon nutrino to the list of M=O particles. Well, if in these cases M=0, applying the simple math of the E=MC2 formula, E (not C?) would ALSO equal 0 for these particles. However, for the photon, at least, clearly there IS some energy involved.

So ... is there any conventional explanation for this apparent contradiction ?

Any professional physicists out there with a ready answer?

I know I already asked a question about the effect of inelastic collision and the victim, but I was wondering if the man would feel recoil if he was firing the shot because of the Kinetic energy. I know that the man would feel recoil due to the law of conservation of momentum, but I'm trying to find a different resolution.

Radioactive substances, and even neutrons and many other sub-atomic particles will break down in half lives.

Some atoms break down, but others don't. Why don't the just all break down at the same time?

What determines which atoms break down and which do not?

If it is not known, are there any theories?

a bus with out window is running at the speed of 40 KM/h,

if a bird is chasing the bus,

can it keep flying at the speed of 40km/h when she gets into the bus?

why the bird can not fly if she was in the bus before the bus start running?

...would the kinetic energy of the bullet be an example of inelastic collision? And would that kinetic energy be transferred because of the bullet being a kinetic projectile?

Are we looking at our own sun when we stare up at the milky way? are we really viewing orbiting Electromagnetic Radiation that has taken many light years to orbit our Galaxy? does this orbiting electromagnetic radiation theory already exist?

Now, before you start to lecture that I need to do my own homework, know this: this is out of my own curiousity! I took physics in high school, but the college I'm attending doesn't offer physics courses, so I'm left in the dark of some of the more advanced topics. I love to learn, and am fascinated by physics, and this topic has always intrigued me! I'd appreciated only serious answers.

if somebody fell off the harbour bridge (16 ppl did when it was being built) how would they die? i know falling into the water u get this air force thing around u and u need to break new air but wat...?

An object is thrown downward with an initial speed of 13 m/s from a height of 64 m above the ground. At the same instant, a second object is propelled vertically from ground level with a speed of 18 m/s. The acceleration of gravity is 9.8 m/s(squared). At what height above the ground will the two objects pass each other?

ive tried talking to everyone about it but nobody can help me out.

suppose I have a perfect vacumm and the container that holds it is weightless. (I know this can't be done but just assume)

how much weight would a 1 cubic meter vacumm (with no weight) lift in normal air. (laws of buoyancy).

I would want to see some math.
