Is energy in vacuum real? How do we know that this energy that can be borrowed and returned immediately is real if virtual particles didn't exist then?
That's amazing. Is it possible to borrow energy from these virtual particles?
While it's not possible to borrow energy directly from virtual particles, the energy associated with their creation and annihilation is what contributes to the vacuum energy. And for a brief moment, that energy can be used before being returned back to the vacuum as the virtual particle disappears.
