Our Sun will someday run out of fuel. Here’s what it will look like when that happens. The fate of our Sun is unambiguous, determined solely by its mass. If all […]
It’s much more complex a question than dividing its mass by the volume of the event horizon. If you want to get a meaningful answer, you have to go deep. If […]
Other forms of expression—nude dancing, flag burning, donating to political campaigns—are protected by the First Amendment. Why not computer code?
A new medical imaging device uses technology developed by particle physicists to produce full-color, 3D images of the human body.
Imagine you had perfect technology and unlimited fuel. How far could you go? Human spaceflight has brought us beyond Earth, but we could potentially venture even farther. The very first launch […]
What do the inventions of the future look like?
How can we use the resources that are already on the Moon to make human exploration of the satellite as economical as possible?
Galaxies are found uniformly everywhere in the Universe, except in the Milky Way’s plane. Here’s why. From the time of their very first discovery, the Universe’s grand spirals have puzzled astronomers. […]
The world of particle physics sure does have surprises, even for the most educated of physicists out there. If you ever take a visit to the physical site of CERN, where […]
The Planck length is a lot smaller than anything we’ve ever accessed. But is it a true limit? If you wanted to understand how our Universe operates, you’d have to examine […]
The second in a three-part series on the history of research on the origin of life.
Can we ever be really sure we’ve learned everything about nature?
As time goes on, every galaxy beyond our local group will speed away from us faster and faster. And yet, more will keep appearing. The farther away a galaxy is […]
The Department of Justice has reached a settlement with Defense Distributed in a landmark decision that will enable the controversial organization to publish CAD files of firearms on its DEFCAD website.
And does it require the idea of ‘negative gravity’ in order to work? The biggest question that we’re even capable of asking, with our present knowledge and understanding of the Universe, […]
Millions of people will watch the 2018 FIFA World Cup this week on TVs and computers. But new technology suggests the next World Cup might be watched through 3D holograms.
New software makes lab work go much faster—and hastens the search for cures.
We’d never flown past or imaged a small, isolated Kuiper belt object before. Here’s what we know so far. As 2018 ended and 2019 began, NASA’s New Horizons flew past its […]
General Relativity has nothing to do with light or electromagnetism at all. So how to gravitational waves know to travel at the speed of light? There are two fundamental classes of […]
It’s the ultimate way to go… and yet, it still isn’t what you’d expect. There are many terrifying ways that the Universe can destroy something. In space, if you tried to […]
Like it or not, agreements made between hackers in Germany, Prague, and elsewhere could reconfigure the economy… and a frightening new world.
The cosmic story of us, from before the Big Bang until today, is a story that all of us share. Enjoy it, in just 200 words. In the beginning, there was […]
A team of researchers at Cornell University has developed a revolutionary battery architecture that could someday increase storage capacity while cutting charge times to mere seconds.
A new study may change the face of astrophysics.
A joint study from U.S. and U.K. universities shows promising results in reducing the rate of cognitive decline.
LEGO folks built an actual, full-sized replica of the Bugatti Chiron—and drove it. What’s next, a Mars rover?
Both effects could be responsible for a redshift. But only one makes sense for our Universe. In physics, like in life, there are often multiple solutions to a problem that […]
The third in a three-part series on the history of research on the origin of life.
Future or extraterrestrial civilizations could create megastructures the size of a solar system.
