Is science close to explaining everything about our Universe? Physicist Sabine Hossenfelder reacts.
If stars don't go supernova at first, they can get a second chance after becoming a white dwarf. But can their companions survive?
The road to intelligent life is a series of hard steps.
As improving biotech offers us longevity, we can prepare to live much better as we age.
In our Solar System, even the two brightest planets frequently align in our skies. But only rarely is it spectacularly visible from Earth.
Lonely humans will become infatuated with AI-fabricated personas.
All human development, from large cities to small towns, shines light into the night sky.
Deep underwater, temperatures are close to freezing and the pressure is 1,000 times higher than at sea level.
If you're a massless particle, you must always move at light speed. If you have mass, you must go slower. So why aren't any neutrinos slow?
Darwin missed an amazing example of evolution.
In a state of "hyperwar," accidents or unexpected AI decisions could lead to widespread devastation before humans could intervene.
The body uses its own electricity to repair wounds. Faster healing may be possible with additional electrical stimulation.
Unless you confront your theory with what's actually out there in the Universe, you're playing in the sandbox, not engaging in science.
The Black, Caspian, and Aral Seas are the last surviving fragments of a body of water that stretched from Austria to Turkmenistan.

We are ~99% genetically identical to chimpanzees. But there are three key traits that separate us.
JWST's revolutionary views arrive in high-resolution at infrared wavelengths. Without NASA's Spitzer first, it wouldn't have been possible.
Using shaped ultrasound, researchers can 3D print objects in one shot.
Baby mice can regenerate damaged hair cells — and now that we know how they do it, maybe we can, too.
Would you want to live in any of these places?
The Fermi paradox (along with the subsequent Drake equation) is so difficult that even brilliant thinkers can make little dent in it.
