Gravitational Wave Background

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense."

'They died long ago.'

In today's bite, we look at a paper that investigates if self-interacting dark matter can accelerate the inspiral of supermassive black holes binaries, and if we can detect this with gravitational waves.

With the confirmation of gravitational waves less than a decade old, scientists are barreling ahead with new detectors to pick up ever more elusive ripples in spacetime

Researchers are trying to figure out what kind of collision made a unique wave signal from 650 million light-years away

Aliens made headlines in 2023, but are we really any closer to finding life beyond Earth? A recap of the best new evidence, and other remarkable stories from the year in space.

The Chinese Pulsar Timing Array (CPTA) collaboration has identified evidence of nanohertz gravitational waves using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST). Despite their shorter data set, their high sensitivity yielded results comparable to other international groups. This

It also torpedoed student debt relief, a decision Biden should undermine with all the executive authority he's got.

It's literally a whole new way to look at the universe.

Several groups around the world are reporting evidence that the cosmos is filled with a background of gravitational waves that is slowly stretching and compressing spacetime

Well… not everything. But also, not not everything

A new study helps solve the "final parsec problem" that has made supermassive black hole formation impossible to explain, pointing to a strange form of dark matter as the key.

The U.S. National Science Foundation's Physics Frontiers Centers program renewed a grant to the MIT-Harvard Center for Ultracold Atoms for $3.6 million per year for six years to fund exploring, understanding, and harnessing mysterious phenomena at the frontiers of physics.

Jocelyn Bell-Burnell: "He happened to be a very observant person."

In eight new papers, the North American Nanohertz Observatory for Gravitational waves (NANOGrav) presents evidence for a gravitational wave background. In this bite, we provide an overview of their results and their implications

Compared to the chaos of Earth, outer space can seem serene. But, thanks to a recent discovery, we now know that the very fabric of the cosmos is being pushed and pulled by gravitational waves — waves powerful enough to distort space-time.
