For many years, cosmologists have claimed the Universe is 13.8 billion years old. A new paper says no, it's 26.7 billion. How do we decide?
Space planes could radically lower the cost of spaceflight.
The brilliant mind who discovered the spacetime solution for rotating black holes claims singularities don't physically exist. Is he right?
Fermilab's TeVatron just released the best mass measurement of the W-boson, ever. Here's what doesn't add up.
One reason saving is hard: We tend to view our "future selves" as complete strangers, and our decisions in the present moment reflect that.
For some reason, when we talk about the age of stars, galaxies, and the Universe, we use "years" to measure time. Can we do better?
Of the world's 300 honey varieties, none is stranger and more dangerous than mad honey.
The zero-point energy of empty space is not zero. Even with all the physics we know, we have no idea how to calculate what it ought to be.
Every proton contains three quarks: two up and one down. But charm quarks, heavier than the proton itself, have been found inside. How?
Here are five things to know before conducting a training evaluation.
With advanced laser technology and an appropriate sail, we could accelerate objects to ~20% the speed of light. But would they survive?
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at higher energies, something even grander happens?
The future of healthcare may bring powerful collaborations between AI and medical professionals.
When you imitate the speech of others, there’s a thin line between whether it’s a social asset or faux pas.
After more than two decades of precision measurements, we've now reached the "gold standard" for how the pieces don't fit.
Fossil Cycad National Monument held America’s richest deposit of petrified cycadeoid plants, until it didn’t.
When constructed well, post-training survey questions can provide a wealth of information that helps guide future design decisions.
Financial illiteracy can become a significant problem. But it’s a problem with a clear solution.
As particles travel through the Universe, there's a speed limit to how fast they're allowed to go. No, not the speed of light: below it.
A single lifetime is more than enough to take you to the limits of the Universe. Right now, there are only three things limiting how far our spacecrafts can take […]
Move over, IC 1101. You may be impressively large, but you never stood a chance against the largest known galaxy: Alcyoneus.
In the quest to measure how antimatter falls, the possibility that it fell "up" provided hope for warp drive. Here's how it all fell apart.
“Hubble’s Law” is only an approximation, and breaks down when we need it most. From anywhere in the Universe, you can choose to look out at any other galaxy that’s present. […]
Here's your gateway to enjoying the best of literature.
Standard probiotics cannot compare to the diversity that your microbes have.
There's still hope for implicit bias training, research shows.
When cosmic inflation came to an end, the hot Big Bang ensued as a result. If our cosmic vacuum state decays, could it all happen again?
From Brahms to Tchaikovsky, here's a curated list of composers whose music has shaped the classical canon.
There are ~400 billion stars in the Milky Way, and ~2 trillion galaxies in the visible Universe. But what if we aren't typical?
