Once only dark energy remains, empty space still won’t be completely empty. Imagine, if you dare, the very end of the Universe. The stars — past, present, and future — have all burned out. […]
Enough mass in one location will always create a black hole. But not all masses are possible. If you take enough mass and compress it into a small enough volume […]
We cannot deduce laws about a higher level of complexity by starting with a lower level of complexity. Here, reductionism meets a brick wall.
If you’ve ever struggled with the strong force, this explanation is a life-saver. If you ask someone to think about some physical phenomenon that’s responsible for any sort of force […]
The Hubble Space Telescope, 32 years after its launch, broke the all-time record for most distant star. It won’t do better.
An optical telescope with a massive 20-foot (6-meter) mirror has an eye-popping price tag of $11 billion.
While many imagine terrifying futures run by AI, Rohit Krishnan is quietly identifying real problems and solutions.
Galactic archaeology has uncovered a spectacular find: the Milky Way already existed more than 13 billion years ago.
Two new studies examine ways we could engineer human wormhole travel.
Today’s young people are intelligent and kind, but they are overworked and burned out.
The odds are slim, but the consequences would be literally world-ending. There really is a chance of a black hole devouring the Earth.
The answer may depend on your lifestyle.
Science can teach us so much about our planet, but something more must compel us to take care of it. If you want to understand our planet, the best way to […]
Willpower alone likely isn’t enough to replace a bad habit with a good one.
There’s a lot to get rid of if we want to get only our Universe out of String Theory. A lot of people, when they learn about String Theory for the […]
Is science absolute? Its truths and discoveries guide us toward the nature of reality, but we must always remain open-minded to revisions.
The concept of ‘relativistic mass’ has been around almost as long as relativity has. But is it valid? No matter who you are, where you are, or how quickly you’re moving, […]
The size of rabbits and hares has long been evolutionarily constrained by competitors roughly their size.
Asking science to determine what happened before time began is like asking, “Who were you before you were born?”
Journaling helped Marcus Aurelius cultivate the emotional intelligence necessary to steer Rome through turbulent times.
Is the “big freeze” our inevitable fate, or can dark energy save us? When we look out at the Universe today, we see sources of light practically everywhere we look. In […]
Company culture is always evolving — sometimes for the worse.
You’ve heard of Stephen Hawking. Ever heard of Renata Kallosh? Didn’t think so.
Scientists at Washington University are patenting a new electrolyzer designed for frigid Martian water.
A new study proposes mysterious axions may be found in X-rays coming from a cluster of neutron stars.
With ~400 billion stars in the Milky Way and 6-20 trillion galaxies overall, that makes for a lot of stars. But not as many as you’d think.
The pulse took just 35 hours to cover the whole world.
Pokémon has people wandering the world to enslave wild and magical creatures so they can fight in painful blood sports. What’s fun about that?
American students are being compelled to specialize earlier and earlier. Here’s what it takes to build a successful physics foundation.
