Scott Aaronson's answer has implications for C-3PO, the universe and the odds that you are a Boltzmann Brain.
Dark matter makes up much of the cosmos, yet no one knows exactly what it is. Soon, physicists may finally solve one of science's biggest mysteries.
New observations suggest your jewelry may have originated from colliding stars. Twinkle, twinkle!
In this case, you get a newly observed kind of pulsating star.
Scientists think a nearby collision of neutron stars could explain the undocumented onslaught of high-energy radiation in the eighth century
Observations of distant gassy discs show how giant gas planets form along with their stars.

It's traveling toward us at about 100 kilometers per second, you know
As the Large Hadron Collider readies to be fired up in Geneva, Physicist Brian Cox explains what it might reveal about the workings of the Universe—and why the grandest scientific instrument ever built is well worth the $6 billion investment
The most powerful and complex science experiment in the history of the universe is finally—after 14 years and $10 billion—about to begin. There's no telling what it may find, and that's entirely the point
Scientists are building ultra-cold systems that mimic the most extreme edges of the universe. Can these analogues help solve the big bang's mysteries?
An astonishing look at some of the universe's most violent events: supernovae, gamma-ray bursts, collisions between galaxies and more
We visit operating rooms, observatories, and islands full of slightly-less-than-rational monkeys to find the young geniuses who are shaping the future of science
Betting on Einstein
Astronomy: Timothy Ferris eyes the amateur asteroid-watchers.
Physicists are praying that their 4-mile-long machine will detect a tiny bit of matter so elusive that some consider it practically divine.
