Smolyaninov as one of the world's leading thinkers about metamaterials. In recent years, he has shown how to use metamaterials to make everything from black holes to quantum foam.
If this magnetic field varies in space in the right kind of way, it's quite possible for this superconducting state to focus light like a superlens. Equally it could also trap light like a black hole.
Nobody has created a magnetic field powerful enough to observe this effect on Earth but such fields must have existed elsewhere. Both Smolyaninov and Chernodub say that in the early Universe, just fractions of a second after the Big Bang, the fields must have been powerful enough to generate these superconducting states.
That has interesting implications. The focusing and trapping effects of this cosmic metamaterial would have focused light in some areas and prevented it leaving others."Therefore, the...behavior of early vacuum may have imprints in the large scale structure of the present-day Universe," says Smolynaniov
