Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
After a generation, we’re finally getting another close-up view. With the science we’re learning, we just might solve its mysteries. “Jupiter instead cooled down below the threshold for fusion, but […]
With quantum teleportation now occurring from Earth to satellites, how long is it before we can teleport a human being? “There would be no Star Trek unless there were transporter malfunctions.” –LeVar […]
Falling into a black hole is forever… but could a tether to the outside pull you back out? “Nobody ever did, or ever will, escape the consequences of his choices.” –Alfred A. […]
Why does the Universe have the properties it has? There may be no natural reason at all. “When you listen to a lecture, you should not have any idea of yourself. […]
‘Let there be light’ isn’t just biblical. It’s science. “By its very nature science knows no boundaries. Walling off any group, for any reason, from full participation damages the entire enterprise […]
Did they perform their analysis sub-optimally? Maybe. But gravitational waves were seen no matter what. “We hope that interested people will repeat our calculations and will make up their own minds […]
How to stay safe and prepare yourself for the show of a lifetime! “Nations, like stars, are entitled to eclipse. All is well, provided the light returns and the eclipse […]
Brown dwarfs are the ultimate failed stars, but they might not remain as failed forever. “[Brown dwarfs] appear to live a more exciting life than we presumed. They are too big […]
Meet LISA, the Laser Interferometer Space Antenna. Yes, it’s giant LIGO, in space, and it’s happening! “Einstein’s gravitational theory, which is said to be the greatest single achievement of theoretical […]
A new planet, bigger than Earth, could be lurking in the outer solar system. But new evidence says ‘probably not.’ “Although we were initially quite skeptical that this planet could […]
The Omega Nebula, the Eagle Nebula and Sharpless 2–54 all line up in space. Here’s a never-before-seen view of them all together! “It shows you exactly how a star is […]
A new podcast, to cover an incredible story of why we can exist at all. “Already in my original paper I stressed the circumstance that I was unable to give a […]
How the Universe’s expansion rate continues to baffle us. “In expanding the field of knowledge we but increase the horizon of ignorance.” –Henry Miller It’s the most fundamental law of special […]
The smart money is still on LIGO, but there sure looks like something funny is happening if the new group is correct. This article was contributed by Sabine Hossenfelder. Sabine […]
Now we know, on every scale. “There is no such thing as perpetual tranquillity of mind while we live here; because life itself is but motion, and can never be without […]
Never heard of SKA, the square kilometer array? Once it starts taking data, you’ll never forget it. “Not all chemicals are bad. Without chemicals such as hydrogen and oxygen, for […]
Gravitational waves and electromagnetic ones don’t need to go together. But physics says it’s possible; what do the observations say? “The black holes collide in complete darkness. None of the […]
Some say it’s more than all of humanity emits in a year. But people say a lot of things. What does the science say? “One volcano puts out more toxic gases — one […]
Every star must eventually run out of fuel and die… but did you know the galaxy itself will come to an end someday? “Unless one says goodbye to what one loves, […]
Constant? Not-a-constant? Or is there a fundamental flaw in the way we’re doing business? This article was written by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in quantum gravity […]
