“the particle’s spin is both in the same direction as its motion (which physicists call ‘right-handed) and opposite its direction (’left-handed’) at the same time. This means that all the fermions move in exactly the same way and can traverse through and around obstacles that scatter normal electrons.”
Sounds like they are little gyro-compasses that hold their masslessness on course. I suppose that if you have no mass, you have no gravity and will not allow particles burdened with mass to deflect you, at least with gravity.
I would suggest that this would be the perfect substance for angels or spirits, passing through “solid” matter and everything, but I do not want to become the Art Bell “correspondent” on what has so far been a Hard Science thread.
Yes, this should lead to a faster Skynet, and help with the development of a more efficient Alcubierre drive (which will destroy objects in local space when decelerating!) We have such interesting times ahead!
When I read about discoveries like this I think about Don Rumsfeld’s bit about the things we don’t know that we don’t know and marvel at how many people believe we understand the merest fraction of what constitutes reality. Talk about unwarranted arrogance.
