Tensoring Heterotic Superstring Theories

The left-moving and right-moving modes of a string can be separated and treated as different theories. In 1984 it was realized that consistent string theories could be built by combining a bosonic string theory moving in one direction along the string, with a supersymmetric string theory with a single… 192 more words


How Lorentz transformation improve the knowledge on space-time concept

Thanks to Lorentz transformation (name given by Henrì Poincarè) we have a theory that aim to give a scientific description of the change of viewpoint from one inertial frame to a second moving one. 805 more words

Determining the causal structure of spacetime (I)

In this series of blog posts, I aim to explain the causal structure of the spacetime solutions in general relativity. Currently, I am working on a special extension of Einstein’s theory (general relativity) which is known as Horndeski theory. 1,046 more words

Superman flying at lightspeed? Umm... no

Back when I was in high school I did a term paper for some class (can’t remember which) ripping the heck out of Superman physics.  Yeah, I was that kind of kid.  691 more words

Does a photon experience time?

My brother Ken asked me, “Is it true that a photon doesn’t experience time?”  Good question.  As I was thinking about it I wondered if the answer could have implications for… 727 more words
