It’s been just a few short years since astronomers made the first ground-breaking detection of gravitational waves, which are the ripples in space-time that propagate outward from especially violent ...

New SP3 Paper Proposes Cosmic Microwave Background Reflects Past and Ongoing Hum as Activity of Real Cosmic Medium ...

In the last decade, astronomers made a major discovery, confirming the existence of gravitational waves. These long-theorized ripples in spacetime are created when extremely massive bodies such as two ...

In September 1977, Voyager 1 was launched to space on a journey to visit Jupiter and Saturn, before heading out to the stars. NASA’s robotic explorer reached the heliopause — leaving the solar system ...

The waves, including some that slowly undulate as they pass through our Milky Way galaxy, occur at different frequencies and oscillate for decades. This discovery could help scientists better ...

Gravitational waves play a cosmic symphony as they pass through our galaxy. Today the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) Physics Frontiers Center released the ...

An in-depth analysis of this background hum is already unraveling the mysteries surrounding the growth and merging of supermassive black holes. June 28, 2023, Mountain View, CA – Gravitational waves ...
