Time crystals just broke a law of physics – and the strange thing is that it shouldn’t exist. For decades, science has told us that perpetual motion is impossible. Energy runs out. Systems settle down. Everything in physics, from your coffee cooling off to stars burning out, follows that rule. But in the strange world of quantum mechanics, not everything plays by the same rules — and now, a bizarre new kind of matter is challenging what we thought was possible, and it’s about to change the way we see the laws of physics.
How time crystals emerged
Time crystals first emerged as a theoretical concept — something that could exist on paper but not in reality. These structures would pulse or shift in a regular rhythm, over and over, without losing energy. In most systems, motion fades unless something keeps pushing. But these crystals don’t need a push. Once active, they keep going.
Over the last few years, researchers have moved from theory to practice, building early versions of these crystals using quantum processors. Each new attempt brought better control and more stability — but even then, most versions only lasted a handful of cycles before breaking down.
Time crystals don’t behave like regular crystals. While ordinary crystals repeat their structure in space — like the patterns in a snowflake or a diamond — these crystals repeat in time. Their internal state shifts in a steady rhythm, flipping back and forth without using energy. That’s not how most physical systems work. Normally, motion fades. Energy drains. But time crystals break that pattern.
The discovery was made at a University in Germany
Back in 2021, Google’s Quantum AI team built a 20-qubit time crystal using their Sycamore processor. A year later, researchers in Melbourne took that further with a 57-qubit version. Around the same time, a team in Hamburg created something new: a continuous time crystal, one that didn’t need external nudges to keep going. That made it more stable — less prone to falling apart.
Now, researchers from TU Dortmund University have taken a major step forward. Their new time crystal didn’t just pulse for a few cycles and fade away. It stayed active millions of times longer than previous versions, making it one of the most durable time crystals ever recorded.
They pulled this off using a series of controlled pulses on a tightly isolated quantum system. By keeping outside interference away and carefully managing the energy flow, the team kept the crystal from absorbing energy — a key rule for these systems to survive. That setup also helped shield it from disturbances, which are one of the biggest challenges in quantum experiments.
The first tests made the crystals collapse
For years, these types of crystals existed only as a wild theoretical concept. Then researchers started building them – first shaky prototypes, then increasingly stable versions. But even the best early attempts barely lasted a few cycles before collapsing in on themselves.
What makes these crystals so strange? Normal crystals repeat in space – think of the geometric perfection of a diamond. Time crystals repeat in time, flipping between states like a metronome that never winds down. They keep ticking without energy input, defying everything we know about how physical systems behave. Normally, things slow down and energy dissipates.
Some compare them to superconductors or magnets — systems that form spontaneous order. But the difference here is key: time crystals don’t settle down. They stay in motion. They don’t reach equilibrium, and that’s exactly what makes them so strange — and so promising. In fact, some magnets can also be used in the search of the cosmos, as NASA found out that it can help read some cosmic waves coming to Earth.
