The constancy of the speed of light is a pillar of modern physics, but questions persist about its absolute universality.

In a study published in Physical Review Letters, physicists have demonstrated that black holes satisfy the third law of ...

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

The Universe is the stage for titanic collisions between massive objects, generating waves that propagate through the fabric ...

The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could ...

CEA Institute of Research into the Fundamental Laws of the Universe (IRFU) has the following research output in the current window (1 August 2024 - 31 July 2025) of the Nature Index. Click on Count to ...

An artistic illustration of the mechanism proposed by Professor Stefano Profumo where quantum effects near the rapidly expanding cosmic horizon after the Big Bang gravitationally generate dark matter ...

By studying the theoretical limits of how light can be used to perform computation, Cornell researchers have uncovered new ...

The Physical Laws Framework (PLF) recognizes that human biology operates according to immutable natural laws — just as gravity governs physics, specific biological principles govern how diseases ...
