Ancient corridors below the French capital have served as its ossuary, playground, brewery, and perhaps soon, air conditioning.

The power of play: our forgotten lifehack.

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 […]

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 […]

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 […]

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.

In one of the ocean’s most lifeless places, scientists discover and resuscitate ancient organisms.

You’ve likely heard of solar energy, but what is osmotic energy?

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 […]

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 […]

The Russian mindset is characterized by cynicism and distrust.

Olive oil leads to the discovery of a law that applies to atoms, superconductors, and even high energy physics.

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 […]

Planet Earth has been around for over 4.5 billion years, but humans? For 99.998% of our planet’s history, humans were nowhere to be found.

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 […]

New experiments find weird quantum activity in supercold gas.

Objective reality exists, but what can you know about it that isn’t subjective. According to some neuroscientists, not much.

A school lesson leads to more precise measurements of the extinct megalodon shark, one of the largest fish ever.

“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. […]

The credibility problem facing the biomedical and public health establishment is, at least in part, a product of its own making.

The closest star system to Earth, just over 4 light-years away, has three stars and at least one Earth-sized planet. Is it time to go there?

The newly discovered galaxies are 62 times bigger than the Milky Way.

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 […]

Neptune holds records in our Solar System, but the Universe gets even faster. Here on Earth, extreme weather events can cause dramatic wind speed spikes. When hurricanes are at their most […]

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 […]

Researchers discover strange behavior in magnetars, ultra-powerful magnetic stars.

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 […]

While Mars is known as a frozen, red planet today, it has all the evidence we could ask for of a watery past, lasting for approximately the first 1.5 billion […]

A recent study tested how well the fungi species Cladosporium sphaerospermum blocked cosmic radiation aboard the International Space Station.

You’ve spent almost a decade gaining extremely specialized skills. But that’s ok; your value is greater than you realize.
