Strange spacetime crystals could organize the fabric of the universe into regular arrangements, potentially triggering a critical collapse that births microscopic black holes with only a tiny nudge of energy.
New research mathematically describes how spacetime undergoes a phase transition similar to water freezing. These theoretical microscopic black holes might have formed during the Big Bang’s intense density fluctuations.
Scientists from TU Wien and Goethe University used pen and paper to solve complex Einstein equations. Their simple solutions describe an unstable intermediate state that either disperses or collapses.
Understanding strange spacetime crystals could trigger stunning collapse
Strange spacetime crystals could trigger a critical collapse of four-dimensional spacetime into microscopic black holes when nudged by an infinitesimal amount of energy. This mathematical breakthrough describes a phase transition where the cosmic fabric organizes itself into regular, crystal-like arrangements, mirroring how undercooled water spontaneously freezes when shaken.
Researchers from TU Wien and Goethe University have theoretically mapped how spacetime transitions from a fluid-like state into an unstable intermediate crystal, potentially birthing asteroid-mass primordial black holes.
This process mirrors undercooled water crystallizing into ice upon being shaken. An arbitrarily small energy injection is sufficient to initiate this dramatic organizational change within the cosmic fabric.
Phase transitions in the cosmic fabric

Strange spacetime crystals could represent a fascinating intermediate state between empty space and a singular point of mass. Just as water at zero degrees knows about ice, this curved spacetime arrangement is poised for change. Depending on the instability, it either disperses back into radiation or collapses into a tiny black hole.
Primordial origins of microscopic black holes
Strange spacetime crystals could explain how non-astrophysical black holes formed during the early universe. Unlike massive stars collapsing, these objects likely emerged from density fluctuations in the hot, dense matter following the Big Bang.
| Property | Astrophysical Black Holes | Critical Collapse Black Holes |

| Required Energy | Massive / Violent | Infinitesimal Nudge |
| Typical Mass | Millions/Billions of Suns | Medium-sized Asteroid |
Scientific importance and theories
Strange spacetime crystals could solve the mystery of why primordial black holes remain elusive despite their theoretical likelihood. This research provides the first exact “pen-and-paper” solutions to Einstein’s equations of general relativity for these structures, proving that complex numerical simulations aren’t always necessary for profound discovery.
The active stage of general relativity

Strange spacetime crystals could reshape our understanding of Einstein’s active stage. While stars curve spacetime strongly, even small masses create curvature. These crystal structures represent a unique, unstable point in the production of the universe that eventually dictates its physical evolution.
Physical properties of critical collapse
The following takeaways from the study by TU Wien and Goethe University Frankfurt highlight the unique nature of these theoretical constructs:
- Spacetime organizes into regular, four-dimensional, crystal-like patterns.
- Instability leads to either thermal dispersion or black hole birth.
- Resulting black holes are classically stable after the initial collapse.
- Solutions involve only elementary functions, fitting into a few lines.
Implications and what comes next
Future experiments must detect primordial black holes to validate this theory. This would confirm that spacetime crystals played a fundamental role in the cosmic evolution of the early universe.
Even without detection, this work enriches our grasp of general relativity. Understanding critical collapse remains a key goal for researchers studying the behavior of the cosmic fabric’s instability.
