    Canceling Electromagnetic Fields

    Hello. Thanks for your posting. Gauge waves "live with their own life?" I don't know what that means. Do you imagine that there are real waves in the real world that don't carry energy and don't have any physical implications?" But the gauge waves are linked to the original charges, for...

    Negative Energy Solutions to Photon Wavefunction

    Yes, I believe that if you carefully work through the standard differential equation for the photon, you will see that there are negative energy solutions. Dirac did indeed get negative mass solutions for the electron and that led him eventually to come up with the idea for the positron...

    Canceling Electromagnetic Fields

    Thanks for your excellent posting. I agree that energy would be conserved, but what about electromagnetic energy? Would not gauge waves carry energy? I believe it to be the case that classical electrodynamics allows for non-conservation of the electromagnetic energy because of gauge...

    Free Parameters In String Theory

    Thanks very much. Could I ask what kind of energies are involved to probe strings? Maybe your answer could be in Gev or Fermis -- as I am an experimentalist. And could I ask you to say a few words about what kind of particle states would be created by strings? And what do you think string...

    Assigning Contributions of Dark Energy to the Cosmos

    Good luck on the problem. I had a fire in my home and must now attend to having all sorts of repairs done and also much cleaning. I wish you all well. Keep an open mind. That's what this old guy would suggest. Best wishes, RoKo

    Assigning Contributions of Dark Energy to the Cosmos

    Hello. Thanks for your effort. Well, about a week ago I talked to the general relativity professor across the street and he said that negative mass particles would produce the opposite space-time curvature as positive mass particles. Also, Dirac introduced negative mass electrons in his...

    Assigning Contributions of Dark Energy to the Cosmos

    Okay, thanks. You say that a positive mass CAN be associated with a repulsive effect. But that does not indicate that it MUST be. It still seems to me that negative mass particles can produce a repulsive force. Can you say with 100% certainty that dark energy is not associated with negative...

    Free Parameters In String Theory

    Okay. Thanks for the information. Could I ask you: When you say compactification, are you speaking of ways of rolling up the various dimensions? I have a fair understanding of quantum physics, but that's about it. I earned my Ph.D. in physics in 1980 -- back in the Dark Ages. Thanks...

    Negative Energy Solutions to Photon Wavefunction

    Hello: My question is simple: Does not the standard differential wave equation from Maxwell's relations lead to both positive and negative energy solutions for a photon's E field? If so, then why do we always throw away the negative energy solutions? Is this just custom? I suspect it is...

    Assigning Contributions of Dark Energy to the Cosmos

    Hello: It has been said that something on the order of 75% of the known universe is comprised of dark energy. But, unless one is assigning a negative value to the putative mass that would be associated with that dark energy, then I don't quite see how one can come up with the 75% figure --...

    Free Parameters In String Theory

    Hello to all: I heard Michio Kaku talk on string theory recently and I thought I heard him say that the theory had no free parameters. But in thinking about the matter, I could not decide what that meant -- if it is true. Could someone please tell me what ingredients go into string theory...
