Re: Today 76 years since Nikola Tesla died
Yes, the universe can be deeply counter-intuitive. 'Common sense' can lead people seriously astray unless that common-sense has been trained by some years of physics education. This is because for most people 'common sense' has only been trained by what they can see and touch, which means no overtly quantum or relativistic effects.
A particle does not have to come from somewhere, provided that its antiparticle also appears at the same time. There is a form of common-sense in physics: conservation laws have to be satisfied, and most symmetries have to be respected.
