Newton’s Third Law Holds: Inside the Real NYU Time Crystal Experiment

Newton Stands: The Experiment That Didn’t Break the Third Law

Newton’s third law was broken. Or so the headlines claimed. The reality, as is often the case, is both more tedious and more fascinating. A team from New York University published an experiment with particles that appear to abusa action and reaction, but what they actually broke was the deep fryer of scientific journalism.

The Time Crystal Experiment

The work exists and is serious: Mia C. Morrell, Leela Elliott, and David G. Grier from NYU’s Center for Soft Matter Research published in Physical Review Letters, volume 136, on February 6, 2026. The system is straightforward on paper: two particles, without external periodic forcing, harvesting energy from a static field thanks to the asymmetry of scattering between different sizes. The result is that the system ends up oscillating on its own. This is novel, but it does not break Newton’s laws.

The third law, in its classical form, dictates that forces between two bodies must be equal and opposite. In systems with fields, linear momentum can be stored in the field itself. As in electromagnetism: two moving charges experience non-collinear forces, but if you sum the field’s momentum, conservation is restored. The case of acoustic particles is similar: the reaction lies in the medium, not in a direct response from the other particle.

The Headline That Cited the Wrong Journal

The news that sparked the debate cited a publication called “The Physical Journal Letters.” That journal does not exist. The actual work appeared in Physical Review Letters, one of the most prestigious physics journals. An error that is no small thing: when it comes to science, the journal’s name matters. Sensationalism deflates when reading the fine print: there is no abusa of the law, only a nuance regarding its conditions of application.

The reaction from professionals was swift: “they haven’t broken anything, they’ve nuanced it,” summarized one analysis. The law of action and reaction remains valid; it is just that its conditions of application have become more delicate than we thought. Or, as another pointed out: magnetism had already thrown a spanner in Newton’s works two hundred years ago.

Skepticism, Conspiracies, and the Lack of Scientific Literacy

The media noise generated everything: from those seeing a monumental fraud to those demanding an anti-gravity engine for their cars. The confusion between a physical law and a social norm was evident when someone proposed a decree-law to guarantee Newton’s compliance with retroactive effect. The irony cannot be more cruel: the third law always holds; what fails is the public’s understanding of science.

This gap has economic consequences. When scientific news is misinterpreted, markets can react: funds are invested in technologies that do not exist, or real advances are abandoned due to a misunderstood headline. The case of graphene, cited in the analysis, is a perfect example: monumental hype, public funds thrown into the pool, and then disappointment. Science advances slowly; headlines run fast.

What Remains After the Noise

The experiment is real and significant: it demonstrates that in complex systems, direct interaction is not the whole game. But there is no new physics replacing Newton. It is a reminder that the frontier of knowledge moves through nuances, not ruptures. The next headline announcing the end of a fundamental law should be viewed with a magnifying glass. And with the correct journal in hand.

We will see more headlines like this, because the format sells. But the “everything breaks” tactic has limited time left. When the reader asks for the source, clickbait is left without a net.
