Scientists Propose New Way to Find Aliens: Detect Their Failing Warp Drives
Speculative new research outlines a method for detecting extraterrestrial civilizations: by catching the gravitational waves produced by the collapse, or failure, of their warp drives. Sounds wild, but the concept is grounded in the principles of Einstein’s general relativity. Warp drives, inspired by Albert Einstein’s grasp of cosmological physics, were first mathematically modeled by physicist…

Behold, Our Galaxy Visualised in Gravitational Waves
No space-based gravitational wave observatory exists…yet. But that hasn’t stopped a team of astronomers from demonstrating how the gravitational universe might look, using simulated data to create a “synthetic gravitational sky.” Gravitational waves are perturbations in spacetime that were predicted by Einstein in his theory of general relativity; as Einstein described them, the waves are…

A Space-Based Gravitational Wave Observatory Is a Step Closer to Reality
The planned LISA mission would involve three spacecraft flying in formation over a million miles apart.

Mirrors That Detect Ripples in Space-Time Were Frozen to Near Absolute Zero
A team of physicists say they’ve managed to nearly freeze the motion of atoms across four suspended mirrors. It’s a mind-twisting feat that strains the very definitions of seemingly simple words like “object” and “temperature.” So buckle up.
