To a certain degree, as they mentioned in the article regarding the casimir effect. While one cannot keep out the quantum foam entirely, it can be restricted to specific wavelengths by altering the volume of the space.
Nope, they actually appear and disappear. The idea is that even in vacuum there’s a certain amount of background energy and that energy can randomly turn into matter-antimatter pairs in what is basically the inverse of matter-antimatter annihilation.
Can quantum particles be blocked or contained or otherwise impeded from entering a vessel?
Are they truly just appearing and disappearing or do they just move so fast (like, faster than C) that it only appears that way?
To a certain degree, as they mentioned in the article regarding the casimir effect. While one cannot keep out the quantum foam entirely, it can be restricted to specific wavelengths by altering the volume of the space.
So with a sufficiently small volume of space, we would have an actual nothing again? Or the foam can go infinitely small?
