This Particle Breaks Time Symmetry
Increasing entropy is NOT the only process that's asymmetric in time. Check out the book: http://WeHaveNoIdea.com This video was co-written by Daniel Whiteson and Jorge Cham You can also check...
==========
Most processes in our universe are time reversible in other words the physics works the same way forwards or backwardsWhich is why you can't tell if I'm playing these videos normally or in reversePeople typically point to entropy as the only exception to this rule. The second law of thermodynamicsstates that the entropy of a system or the amount of disorder always increases with time *buzzer sound*But increasing entropy is an emergent property, the result of the motions of many many particlesWhich raises the question:Can fundamental particles themselves tell the direction of time?Or, in other words, is there a physical process on the scale of individual particles that looks differentforwards vs backwards? The answer surprisingly is yes.In particle phy...
