A study by scientists at the Hong Kong University of Science and Technology has concluded that supraluminal velocities are impossible for single photons. This apparent confirmation of Einstein’s dictum that the speed of light in a vacuum is an absolute limit puts the kibosh on the possibilities for time travel–or so the team’s lead researcher, Du Shengwang, would have us …
How Would You Bet?
Lots of news today about a finding that under some conditions neutrinos may (I emphasize may) travel faster than the speed of light, a clear contravention of a basic tenet of physics. In this light (yes, that’s a joke), I found this little item to be of interest: Source: https://xkcd.com/955/ Given all the pronouncements lately about changes to established paradigms—often …
