Is there a difference between science and magic?

Despite the old Arthur C. Clarke quote, "Any significantly advanced technology is indistinguishable from magic.", I have firmly held on to a reverence toward science, at least the scientific method of observing and testing nature. Certainly some areas of science, such as medicine, chemistry, and Newtonian physics have provided us with rational benefits. Now, however, there are parts of science that are hard to distinguish from magic.

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.

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.”
