When Dirac tried to combine Quantum Mechanics and Special Relativity. Wasn't he initially worried that one was undeterministic (QM) and the second was continuous (SR). They are supposed to be incompatible. yet he combined them. Did Dirac do it by just considering the time dilation and other relativistic components like Lorentz transformation? I thought the essense of Einstein Special Relativity was the worldlines.. but you know quantum particles don't have worldlines.(adsbygoogle = window.adsbygoogle || []).push({});

This also means SR worldlines are not the main aspect of relativity and the concept can be discarded, isn't it. You can make equations that combine QM and SR without taking it into account. What part of SR is the most important then creating QFT? We newbies are only exposed to the relativity geometry and worldlines so we need to ask this.

I hope the mentors can give others chance to answer this and not just lock threads without mercy (this can leave many questions left unanswered and make newbies nights sleepless). Ty
