    Hi Jilan, Thanks for the message. Apologies for the delayin response. I fell ill due to sunstroke and was also busy doing my admission to the new university at the same time. Do you think we can do anything to take this idea of "creating gravity by bending of light" ahead?

    Hi Jilan.Where are you from? What do you do? Are you a physicist?

    It might be a good strategy to start by considering the much simpler case of two "stationary" world-lines (i.e. field lines of the timelike Killing vector) that are extremely close together, and very...

    I can make a far simpler idea of curved space: Take two apples, put them high up in the atmosphere some distance apart and drop them, they don't fall straight down, but move closer together...

    Everyone, please remember that "speed" is a concept that is not as straightforward as it would initially seem, because we need to distinguish between coordinate speed and proper speed. In curved...

    You have to be very careful here, because electric charges in "free fall" do not exactly follow geodesics in space-time; the equivalence principle applies only to uncharged particles. The reason for...

    This may surprise you, but that is not necessarily true. For example, in the exterior Kerr space-time the length of world-lines from (1) to (2) may be different than the one going from (2) to (1),...

    Photons do interact, but as I showed earlier on QED is absolutely clear that it is only possible with the help of other fields which do carry charge. If you insist that photons interact directly (in...

    No. A real photon is a real thing that propagates through space at the speed of light. A virtual photon isn't a photon. Read Matt Strassler's article. Or have a look at the near and far field...

    Maybe information is the only thing that does have a fundamental existence.

    It is a false impression because the part of the quote you omitted was the part of the quote that indicated how QED models electron-positron pair production as a higher-order process. The part of the...

    It is predicted by theory and confirmed experimentally. The simplest way of putting it is that the apparent charge of a particle increases very slightly if you get really close to it, as though it...

    I don't know Jilan. I'd say that the running of the fine structure constant is accepted and correct. I'd also say that variations measured by Webb et al (see Changes spotted in fundamental constant -...
