Dark-energy evidence suggests the universe will end in a “big crunch” roughly 20 billion years from now. The universe is nearing the halfway point of what may be a 33-billion-year lifespan, according ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

Tel Aviv scientists predict ancient radio signals from the early Universe that could reveal how dark matter shaped stars and ...

Distance scales from the Planck length to a 93-billion-light-year observable universe expose extreme limits of physics and hint at unknown phenomena where current laws break down.

In the quest to unravel the mysteries of the universe, physicists are revisiting a 150-year-old theory that could illuminate ...

Why did they form at that time? Astronomers know from observing distant exploding stars that the size of the universe has ...

Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter.

MIT researchers have devised a new molecular technique that lets electrons probe inside atomic nuclei, replacing massive particle accelerators with a tabletop setup. By studying radium monofluoride, ...

Modern multiverse fiction incorporates real physics equations and string theory principles rather than relying on pure ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, ...

Russell was one of the people that established the reputation of Princeton Plasma Physics Lab as the place to do plasma ...

Scientists achieved a milestone in quantum research by using Google’s quantum processor to simulate the interactions of ...
