    Smile A Question

    First I just want to say Astronomy Cast is the best podcast ever, I listen to it on my bus to school and while im riding my bike I even converted my mate to it after I was telling him about particle/wave duality. Im wrecking my science teachers brains because I keep asking questions, so I thought i'd bring them here.

    1 How does Hydrogen fusion create helium, when hydrogen has no neutrons?

    and if E=mc/\2 doesnt m=e/c/\2 (e over c squared) so if we had the energy of 1 photon couldnt we find the mass of light.
    Now I know that light has no mass but if this equation works for regular matter it should work for light,or is that the amount of energy that acts like mass,but is not mass so can be warped by gravity?

    Look what you have done to me astronomy cast, making me question physics(very indirectly)

    For stars bigger than the Sun, the CNO Cycle (Wikipedia) does the trick.

    And energy can warp space like mass, more or less.

    You might also want to look up De Broglie waves, where matter has wave like properties.
