Simulations suggest a breakthrough in understanding how turbulence develops

by quasarn01 | Mar 11, 2026 | Latest in Physics

A new study revisits a century-old question about how turbulence starts. The findings could potentially influence not only aircraft engineering but even the design of mechanical heart valves, and treatment of heart disease. The study is published in Scientific...

Fluid simulation at unprecedented scale provides toolkit for fundamental physics and applied fluid engineering

by quasarn01 | Mar 11, 2026 | Latest in Physics

What governs the speed at which raindrops fall, sediment settles in river estuaries, and matter is ejected during a supernova? These questions circle around one, deceitfully simple factor: the rate at which a fluid filled with particles mixes with a particle-free one....

Galaxy-group motion suggests slower expansion in our cosmic neighborhood

by quasarn01 | Mar 11, 2026 | Astronomy

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding cosmic flow. The results indicate that the local universe is expanding...

Astronomers collect rare evidence of two planets colliding

by quasarn01 | Mar 11, 2026 | Astronomy

Anastasios (Andy) Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The star, named Gaia20ehk, was about 11,000 light-years from Earth near the constellation Puppis. It was a stable “main...
