Physicists Created the First-Ever Time Crystals
A time crystal, without going into much detail, is an object appearing to have movement while remaining at its ground state — an idea proposed by theoretical physicist and Nobel laureate Frank Wilczek in 2012.
Time crystals exist as some sort of loophole in the law of physics, by existing in motion without energy consumption — a spontaneous break in time-translation symmetry — now made observable in time. However, in as much as the movement made by time crystals do not use consume energy, neither can it produce any. Also according to Tech Review, “Of course, it would never be possible to extract energy from this motion – that would violate the conservation of energy.”
