I decided it was time for another go at explaining Special Relativity.
I remain annoyed at how few people really get it, even amongst avid SF consumers, who have gotten entirely too accustomed to generations of SF writers papering over the FTL issues with technobabble, 'cause we need that galactic empire, don'tcha know.
The idea is to do this with basic geometry you knew or could have learned about in 6th grade plus a bit of algebra (up to Pythagorean Theorem, which I *d…

On the Deepest Search for #GalacticCenter Pulsars and an Examination of an Intriguing #MillisecondPulsar Candidate: #Pulsar in the Milky Way’s Center: https://news.columbia.edu/news/researchers-announce-discovery-possible-pulsar-milky-ways-center - confirming a pulsar star would enable unprecedented tests of General Relativity. Such a discovery would revolutionize physics.

« The more important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplanted in consequence of new discoveries is exceedingly remote…. Our future discoveries must be looked for in the sixth place of decimals. » Albert Michelson 1894
En 1905, Einstein published the theory of special relativity
