I was hoping to put together a Javascript tool for visualising the Red-shift of different celestial phenomena over different distances.Sadly it didn’t take long to learn the dominant file format for spectra (.SPC) is binary encoded and pretty complex; as a […]

Time Dilation Calculators

Lorentz Factors Adopted by Poincaré and Einstein in 1905 the Lorentz factor is a measure of how much measurements of time, length, and related properties change while matter/observer is moving. It measures the difference in time-space scales measured from two frames of reference (moving and rest) at relativistic speeds.We can calculate this factor as such: […]
