They say that something can’t be created out of nothing, but that’s what researchers may have done- sort of. Quantum theory states that even in a vacuum some particles do exist. Testing this, scientists in Sweden claim to have made sparks in a vacuum.
According to quantum theory, empty space is, well, not that empty after all. Rather it is full of virtual particles – particles that quickly blip in and out of existence. Theory states that a mirror can absorb energy from some of these virtual photons, and re-emit it as actual photons. Of course, this only works if the mirror is traveling through the vacuum at nearly the speed of light, making it difficult to prove, to say the least.
