... Observation tells us that physical quantities are not continuous down to the smallest scales, but tend to be discrete. O.K., we can live with that. But QM has another surprise: if you look small enough, matter – that is, “particles” –start to exhibit wavelike behavior. We have already seen hints of ...

Is gravitational mass of a composite quantum body equivalent to its
... It is known that gravitational mass of a composite classical body in general relativity is not a trivial notion and is a subject of several paradoxes. One of them is related to application of the so-called Tolman formula [5] to a free photon, which formally results in a doubling of photon active gra ...
