Forces have mediator particles. Electromagnetism is mediated by the photons, for example. So most of the decay of this excited dark matter particle would be this unknown mediator. The excited state ...

In November 2024, gravitational-wave detectors recorded the violent merger of two black holes billions ...

Gamma-ray bursts are the most violent explosions in the universe. In a fraction of a second, they can release more energy than the sun will emit across its entire 10-billion-year lifetime. Most are ...

Thunderstorms in the tropics are literally radioactive, according to a team of researchers that recently used a retrofitted spy plane to survey the phenomena. The team’s research was published in two ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Thunderstorms create a lot of wind, rain, and lightning, but many ...

The collision of two lightning-bolts-in-the-making spawned an exceedingly brief but extremely energetic flash of gamma rays. This first-of-its-kind observation may help explain an origin of some of ...

A single particle cut through the Mediterranean in February 2023 carrying an almost absurd amount of energy. Detected deep ...

Radiation is energy that moves from one place to another in a form that can be described as waves or particles. We are exposed to radiation in our everyday life. Some of the most familiar sources of ...

NASA sent a retired Cold War spy plane on a storm-chasing mission, and it discovered that big thunderstorms are very radioactive. Large thunderstorms produce so much gamma radiation that the clouds ...
