Just for the record, one way to synchronize two clocks would be for one clock to send out a signal at ##t_1 = 0## and when that signal...

ersmith replied to the thread I Understanding the historical shift away from absolute simultaneity.Putting aside the history for a moment, the significance of universal simultaneity in Newtonian mechanics comes from there being no...

ersmith replied to the thread I Understanding the historical shift away from absolute simultaneity.It should perhaps be noted that while LET can reproduce all of the predictions of SR, it does not naturally extend to a theory of...

##c## is effectively a unit conversion factor in this context, and appears so we are using the same units in all four dimensions. It's...

ersmith replied to the thread A A Question on the TOV Limit: Continuous Forces vs. a Discrete Trigger.One more thing to note is that even if we disregard quantum mechanics and treat the neutron star as a collection of classical particles...
