@lorenschmidt@m0j0hn overall, i can really recommend watching Minute Physics' video series on this, this is a topic that is way more intuitive in video format(as intuitive as relativity can get lol) than just plain text: https://t.co/e8GQy15289
@lorenschmidt@m0j0hn Relativistic energy is a different beast entirely. Looking at kinetic energy(E=1/2mvยฒ) we quickly notice that all relevant parameters(mass,lenght,time) change under relativistic conditions, posing the question: is energy still conserved here? TL,DR: you just discovered that E=mcยฒ
@lorenschmidt@m0j0hn The thing with relativity is that you,the Observer โข๏ธ,are basically always considered stationary. So basically all relativistic "distortions" are calculated with just the absolute velocity compared to what you're looking at. Funnily enough, acceleration drops out of all formulas.
