When Hurricane Helene hit the southeastern United States last month, it caused widespread power outages and devastating ...

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that ...

High-frequency gravitational waves, like high-frequency light, have shorter wavelengths and are more energetic; low-frequency ...

That gravitational waves event was accompanied by a flash of light spread across many wavelengths, and analysed by multiple telescopes. In contrast, the new detection, made on 25 April last year ...

Halverson develops millimeter-wavelength instrumentation to study the origins of the universe through observations of the Cosmic Microwave Background (CMB). Observations of the CMB can be used to ...

The equation needed when studying waves is: wave speed = frequency x wavelength. A ripple tank allows you to study transverse waves in water. Ripple tanks vary a lot in how they look, but usually ...
