One truly elegant hypothesis of physics is the "zero-energy universe" hypothesis. It proposes that the net sum of the energy in the universe perfectly equates to zero. According to the idea, if you ...

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the ...

Coupled climatemodels are prone to “drift” (long-term unforced trends in state variables) due to incomplete spinup and nonclosure of the global mass and energy budgets. Here we assess model drift and ...

A new estimate of the ghostly particle’s maximum possible mass brings physicists a tad closer to understanding the universe. By Katrina Miller Katrina Miller studied neutrinos in graduate school, but ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics. In the fall of 1915, the foundations of physics ...

During the 2026 Winter Olympics, athletes will leap off ramps, slide across ice and spin through the air. These performances ...

The quantum physicists Sandu Popescu, Yakir Aharonov and Daniel Rohrlich have been troubled by the same scenario for three decades. It started when they wrote about a surprising wave phenomenon called ...

Current theories suggest that W and Z bosons acquire mass from interactions with the Higgs scalar field, but a new study suggests that the higher dimensional structure of spacetime could be the actual ...
