An electron can spin both clockwise and anti-clockwise at the same time.
If you were to go round in a circle at a speed close to the speed of light, you will end up traveling forward in time.
GPS systems work accurately only because they take into account that time on earth runs more slowly on earth than it does in outer space, as the earth’s gravity slows time down. As already predicted by the general theory of relativity.
Two atoms can be “entangled”. They can be far apart and if you do something to one of them than that instantaneously affects the behaviour of the other atom, even if it is at the other end of the Universe.
For a photon, a particle of light, time stands still. Past present and future all collapse down to one eternal moment.
Which one of us might want to be a photon for a “moment”… And which one can resist the temptation to study quantum physics…
