US scientists have found that the strange behavior of cuprates, a superconductor copper composite group of materials, have a resistivity and rate of electron scattering which are directly proportional to temperature, instead of being proportional to the square of the temperature as happens in other superconductors, which are ruled by Fermi's laws.
According to co-researcher Hong Liu: there's really no theory of how to explain that.
Except String Theory.
Using a key property of String Theory, known as gauge-gravity duality, which states that each quantum (gauge) phenomenon has an analogue in the realm of gravity, they found that black holes seem to behave in the gravitational field exactly as non-Fermi liquids, like said cuprates, do in the quantum one.

It is not the first time that the String Theory, that should unify Quantum Mechanics and General Relativity, seems to be confirmed empirically in this strange world of "warm" superconductors. I already mentioned previous research a year ago.
However opponents seem whinny about the supposed non-demonstrability of String Theory, which actually has to do with some complains regarding the impossibility to falsify it at the "usual" particle accelerator energies. But I suspect that they are rather too inclined to materiality and lack holistic vision, which is necessary for a theory of all, an explanation not just of this universe but of the metaverse itself, of "God" if you wish. Of course, such explanation must also work in this world but there is no reason to think that this universe is the only thing existing, specially because we know it has a beginning, it is finite, hence there must be something else. It is more than probable that to explain some phenomenons at the very edges of this universe, as happens with black holes, the big bang and others, we need to explain not only the 3+i dimensional sub-reality we exist in but all, absolutely all, even what we cannot perceive easily. Only String Theory reaches that far, which is a virtue rather than a defect.
But hyper-materialists are uncomfortable with a reality with more than the usually experimented dimensions and surely they were uncomfortable with relativity and its folding of space and time in the past as well. They prefer particles to be objects, even if they have to be Newtonian non-dimensional points, and that is a psychological barrier. But what's wrong with a string or a brane? Nothing, in fact it's more natural for the relativistically-minded: you don't need anymore an unreal punctual electron immersed in quantum uncertainty but you actually have a most reasonable string that vibrates, which is actually what electrons or photons seem to do, as they are neither here nor there as punctual particles or they are particle and wave at the same time... only brane mechanics, i.e. String Theory, can explain that, it's pure logic... at least for me.
Is it an issue to need more dimensions? Not at all. There must be something else than this universe and therefore there must be further dimensions, maybe infinite. This is also pure logic. I am persuaded that great thinkers of the past such as Spinoza or Einstein would have agreed with this theory. But I learned the basics of these physics from one of the most celebrated geniuses of our time, Stephen Hawkins. So it sounds quite interesting. Authority however is no proof, the proof is in superconductors, it seems.
