As you might suspect, it is all related to quantum physics. Matter just doesn't exist at a certain time and place, it has a probability of existing. This is starting to lead to all sorts of magical things. We learned about this weirdness during Quantum Week, but this new experiment is, well…magical.
Physicists in Sweden say they have managed to create light from vacuum, the closest thing to empty space known to exist.
In findings published this week in the research journal Nature, the scientists said they verified an effect predicted over 40 years ago by capturing some of the particles of light, or photons, that constantly appear and disappear in the vacuum.Taken from here.
The experiment is based on one of the most counterintuitive, yet, one of the most important principles in quantum mechanics: that vacuum is by no means empty nothingness. In fact, the vacuum is full of various particles that are continuously fluctuating in and out of existence. They appear, exist for a brief moment and then disappear again. Since their existence is so fleeting, they are usually referred to as virtual particles.
Chalmers scientist, Christopher Wilson and his co-workers have succeeded in getting photons to leave their virtual state and become real photons, i.e. measurable light.

I always question how main stream media reports science experiments, so be sure to search for more reports on this experiment. I'm sure there will be plenty of reports.

This takes us back to British geneticist J.B.S. Haldane: "Now, my own suspicion is that the universe is not only queerer than we suppose, but queerer than we can suppose."
As an extra bonus, one other quote from Haldane:
“Theories have four stages of acceptance:
i. this is worthless nonsense,
ii. this is interesting, but perverse,
iii. this is true, but quite unimportant,
iv. I always said so.”
