Here is a recent experiment to make light where nothing exists:

One of the weirdest predictions of quantum mechanics is that the vacuum of space isn't really empty. Because of the uncertainty principle, quantum theory predicts that a constant foam of "virtual particles" are flitting in and out of existence inside the void. Even weirder, these virtual particles can have real effects. This week, a paper in Nature demonstrates just such an effect: if you jiggle a mirror very close to the speed of light, you can turn pairs of virtual light particles into real ones. The work was done by Christopher Wilson and a group based at the Chalmers University of Technology in Sweden. Rather than trying to vibrate a real mirror at near light speed, the team tweaked a superconducting circuit to create a wiggling, mirror-like electrical surface.

So it seems possible that something could be made "visible" in a place where nothing was visible before. And, it was made possible with superconductors.

Some more on this astonishing phenomenon:

Chalmers scientists create light from vacuum

"PRESS RELEASE: Scientists at Chalmers have succeeded in creating light from vacuum – observing an effect first predicted over 40 years ago. The results have been published in the journal Nature. In an innovative experiment, the scientists have managed to capture some of the photons that are constantly appearing and disappearing in the vacuum."

"The “mirror” consists of a quantum electronic component referred to as a SQUID (Superconducting quantum interference device), which is extremely sensitive to magnetic fields. By changing the direction of the magnetic field several billions of times a second the scientists were able to make the “mirror” vibrate at a speed of up to 25 percent of the speed of light."

It reminds me of the opening of Toge's poem:

The basis of the universe is Eternity (muguk) and, at the same time,
the Supreme Ultimate (t'aeguk).

The Supreme Ultimate moves and gives birth to Yang
(the positive and active).

When this movement reaches its peak,
it achieves serenity, which then gives birth to Um
(the quiet and passive).
