A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

Robotic-assisted solar construction moves from pilot to production through deep field integration Robotic-assisted installation lets experienced crews scale without burnout, improving speed, ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

Dark matter keeps getting blamed for the universe’s big patterns while staying stubbornly out of reach. You cannot see it, touch it, or capture it.

Deep inside a nearby galaxy cloaked in thick clouds of gas and dust, astronomers have uncovered a surprising treasure trove ...

A new study suggests that dark matter may consist of particles with different masses. By introducing a two-component self-interacting dark matter model, the researchers show that both the low-density ...

Study Identifies Systematic Instabilities in Quasar Dipole Measurements. New Analysis Challenges "Lopsided Universe" ...

Astronomers have spotted a heart in the cosmos — not Cupid's doing, but a dying star shedding its layers — just in time for Valentine's Day.

A 1 Gw orbital data center would cost roughly $42.4B—almost three times its ground-bound equivalent.

Something genuinely strange has just happened in fundamental physics: an underground neutrino telescope in the Mediterranean ...

NASA's new SPHEREx observatory has released its first all-sky cosmic map. This map uses 102 infrared wavelengths to reveal the universe in unprecedented detail. Scientists can now study cosmic ...
