how can a particle be in two places at once?
In: 3
It can’t, and it’s not.
However, particles also behave as waves, with smaller particles being more wavelike and less particle-like. Waves exist as a distribution of energy across some amount of space.
The confusing part is that sometimes these waves have to interact with stuff (like camera sensors) at which point they turn into a particle to do the interaction. However a single particle cannot interact with two camera sensors at once. What it CAN do is have a 50% chance of interacting with either sensor. If you have a large number of sensors spread out in a line, mapping out the chance of the particle interacting with each sensor will look like a statistical distribution that roughly matches the wave distribution.
