The controversy over the universe’s expansion rate continues with a new, faster estimate.
In one of the ocean’s most lifeless places, scientists discover and resuscitate ancient organisms.
Is that required for detectors like LIGO and Virgo to work? Whenever any two things in the Universe interact at the same location in spacetime, one thing always remains true about […]
Not nearly well enough. And we should all be concerned. In 1859, the science of solar physics truly began with the largest eruption in recorded history: the Carrington event. Prior […]
Anxiety can be good or bad. It turns out that it’s really up to you.
You’ve likely heard of solar energy, but what is osmotic energy?
Named M51-ULS-1b, it’s certainly a curious astronomical event. But the evidence is far too weak to conclude “planet.”
A famous thought experiment from the 1970s is more relevant today than ever before.
The theoretical reasons to expect it are compelling, but the technology required to detect it is unfathomable. All throughout our galaxy, millions of black holes of a variety of masses […]
During World War II, Nazi engineers allegedly tried to create UFO-shaped military aircraft.
One man studied apes for 50 years. He says nature isn’t as cruel as you think.
Some scientists believe the lightning-produced frequencies may be connected to our brain waves, meditation, and hypnosis.
When we look out at the Universe, even with Hubble, we’re only seeing the closest, biggest, brightest galaxies. Here’s where the rest are.
Olive oil leads to the discovery of a law that applies to atoms, superconductors, and even high energy physics.
Even if you remove everything you can from the Universe, some energy will still remain. Here’s what that means. Imagine, if you can, what it would mean to have a Universe […]
A new survey, the DESI Legacy Imaging Survey, has found more lenses than all others put together. One of Einstein’s most revolutionary predictions is that mass bends light. During a […]
Ancient corridors below the French capital have served as its ossuary, playground, brewery, and perhaps soon, air conditioning.
An interview with filmmaker Jason Sussberg about his new film about Stewart Brand and the importance of culture in achieving progress.
New experiments find weird quantum activity in supercold gas.
And after years of mystery, we finally know where they come from. Here on Earth, thunderstorms and accompanying lightning strikes represent tremendous releases of energy. It was way back in 2011 […]
From exoplanets to supermassive black holes to the first stars and galaxies, Webb will show us the Universe as we’ve never seen it before.
With just a few more neutron star mergers, we’ll have the best constraints of all-time. How fast is the Universe expanding? Ever since the expanding Universe was first discovered nearly […]
With three colors and three anticolors, there aren’t actually nine gluons; only eight. One of the most puzzling features of the Universe is the strong nuclear force. Inside every proton or […]
Since 1957, the world’s space agencies have been polluting the space above us with countless pieces of junk, threatening our technological infrastructure and ability to venture deeper into space.
According to the Standard Model, the leptons and antileptons should all be separate, independent particles from one another. But the three types of neutrino all mix together, indicating they must […]
The power of play: our forgotten lifehack.
There was less than a 2 second delay between gravitational waves and light, but that’s incredibly meaningful. There’s an important rule in relativity that — as far as we know — all objects must […]
A recent study tested how well the fungi species Cladosporium sphaerospermum blocked cosmic radiation aboard the International Space Station.
We’re still not sure what the ultimate question is. Here are 5 excellent candidates. One of the most amusing stories in all of science fiction is Douglas Adams’ The Hitchhiker’s […]
