The Race To See The Black Hole At The Center Of Our Galaxy
We've never observed a black hole directly, but with a wild collection of telescopes, these astronomers are determined to be the first. What Can Giant Telesc...
3D graphene has 5% of the weight and 10x the strength of steel
A team of MIT engineers has successfully designed a new 3-D material with five percent the density of steel and ten times the strength, making it one of the ...
Boeing: Lightest. Metal. Ever.
Microlattice is the lightest metallic structure ever made. At 99.99% air, it's light enough to balance on top of a dandelion, while its structure makes it st...
Vera Rubin, Astrophysicist Who Confirmed Existence Of Dark Matter, Dies At 88
The astrophysicist's groundbreaking research on spiral galaxies provided evidence of invisible dark matter. She was a pioneer in an era when women were excluded from many astronomy programs.
Researchers use world's smallest diamonds to make wires three atoms wide

Photos: Inside the Oakland 'Ghost Ship' Warehouse Building Before It Caught Fire
Images from inside the warehouse commonly referred to as the "Ghost Ship" that was the site of one of the deadliest fires in Oakland history.
Was Einstein WRONG about the speed of light?
A duo from Imperial College London and the Perimeter Institute in Canada have developed a model that could help to show that the speed of light fluctuated in the early universe.

NASA Mystery: Electron 'Superhighway' Traveling at Speed of Light Discovered Just Outside Earth's Magnetic Field
"This is a puzzling case because we're seeing energetic electrons where we don't think they should be, and no model fits them," said David Sibeck, co-author and THEMIS project scientist at NASA Goddar...
Quantum Physicists Probe Fabric of Spacetime to Solve Mystery of Dark Energy
One of the great mysteries of the cosmos is why it is expanding at an apparently accelerating rate. Physicists have suggested an outward force, dubbed "dark energy," causes this expansion, but they ha...
We May Have Found a Way to Cheat the Second Law of Thermodynamics
Physicists created a new quantum theorem for entropy, and included is a possible exception.
The case for black holes being nothing but holograms just got even stronger
If anything can sum up just how little we truly know about the Universe, it’s black holes. We can’t see them because not even light can escape their gravitational pull, we have no idea what they’re ma...
