"GW241011 and GW241110 are among the most novel events among the several hundred that the LIGO-Virgo-KAGRA network has ...

The findings confirm the presence of rare binary systems and suggest certain black holes are second-generation, forged in ...

Theoretical physicist Alex Lupsasca is pushing for a space telescope to glimpse the thin ring of light that is thought to surround every black hole.

Identifying the gravitational waves from black holes binaries could also make it clearer to detect primordial gravitational ...

Most explanations rely on "dark energy" to explain the Universe's accelerating expansion rate, but a new study takes a different path.

A new paper presents a method for distinguishing between different sources of nanohertz gravitational waves. Pulsars may be revealing faint ripples in the fabric of the universe, ultra–low-frequency ...

A team of cosmologists in Finland and Poland have proposed that the accelerated expansion of the universe, usually explained by dark energy, may actually be the result of "Tardis regions" of spacetime ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

Satellite operator Telesat plans to use Aalyria’s Spacetime networking tech for its Lightspeed satellite constellation. Spacetime tries to find the best route for customer data between any two points ...

What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some ...

In a recent exhibit, the artist wove fantasy and physics to illustrate the temporal funk of living through a pandemic. Early in the COVID-19 pandemic, when New York City went into lockdown, artist ...
