spacetime crystals collapse into tiny black holes explained by new analytical formula, offering insight into early‑universe black hole formation – read the key
A team from Goethe University Frankfurt and TU Wien has published an exact analytical formula describing how a “spacetime crystal” can tip into a microscopic black hole, a breakthrough that could reshape theories of primordial black‑hole formation [1].

Physicists have long relied on computer simulations to explore critical collapse—the delicate threshold where gravity can either dissipate or form a black hole. In 1993, Matthew Choptuik’s simulations revealed a self‑similar pattern that hinted at a crystal‑like state of spacetime [2]. The Frankfurt‑Vienna team now derived a closed‑form solution by extending Einstein’s equations to an infinite‑dimensional limit and then mapping the result back to our four‑dimensional universe [1]. This “large‑D” trick makes the otherwise intractable equations tractable, allowing systematic refinements for higher precision [1].
The formula shows that once a spacetime crystal reaches the critical point, adding an arbitrarily small amount of energy can drive the system into a black‑hole state. Such microscopic black holes could have formed in the extreme density fluctuations of the early universe, offering a plausible mechanism for primordial black‑hole production—a candidate for dark matter [1]. The researchers stress that the crystal is an unstable intermediate; without the extra energy it would simply dissolve back into ordinary spacetime [2].
The study provides the first exact mathematical description of a spacetime crystal’s fate, turning a long‑standing computational curiosity into a concrete analytical tool and opening new avenues for probing the universe’s earliest moments.

It is a constant flux of low‑frequency gravitational waves generated by numerous supermassive black‑hole mergers throughout cosmic history, which subtly stretch and squeeze spacetime.
By precisely tracking the relative positions of quasar pairs, any tiny apparent motions induced by passing gravitational waves can be identified against Earth's own motion.
A spacetime crystal is a regular, lattice‑like configuration of spacetime that can arise during critical collapse; a small addition of energy can destabilize it, causing it to collapse into a microscopic black hole.
They represent a possible outcome of early‑universe critical states and could explain the existence of primordial black holes, offering insight into fundamental aspects of gravity and quantum physics.
