Two of the greatest mysteries in cosmology are the nature of dark energy and the apparent conflict in our measurements of the expansion rate of the...

From hoverboards to flying cars to cloud cities, anti-gravity is a staple of science fiction and our dream of a less Earth-bound future. But in the...

This is what we astronomers call a blob, or a smudge, if you want to get really technical. It may not look like much from here, but what do you...

It's not too often that a giant of physics threatens to overturn an idea held to be self-evident by generations of physicists. Well, that may be the...

EMPs aren’t science fiction. Real militaries are experimenting on real EMP generators, and as Starfish Prime showed us, space nukes can send...

In 1974 we sent the Arecibo radio message towards Messier 13, a globular cluster near the edge of the Milky Way, made up of a few hundred thousand...

Space seems fundamental. To build a universe, surely you need something to build it on or in. Many, maybe most physicists now think that the fabric...

There are four fundamental forces - the strong and weak nuclear forces, electromagnetism, and gravity. Except maybe gravity is no more fundamental...

Of all the astronomical phenomena you can witness, the total solar eclipse has to be the most visceral--the most in-your-face reminder that our...

The Moon has been one of the most important theoretical stepping stones to our understanding of the universe. We’ve long understood that it...

Meet Alice and Bob, famous explorers of the abstract landscape of theoretical physics. Heroes of the gerdankenexperiment—the thought...

In the far future we may have advanced propulsion technologies like matter-antimatter engines and compact fusion drives that allow humans to travel...

Black holes are inevitable predictions of general relativity—our best theory of space, time and gravity. But they clash in multiple ways with...

Cern's Large Hadron Collider routinely collides particles at energies equivalent to a fraction of a second after the Big Bang. If this worries you,...

So you’ve decided to jump into a black hole. Good news: as long as the black hole is big enough you can sail through the event horizon without...

Solar activity is still increasing in a sunspot cycle that is proving way more intense than scientists predicted. Just how much stronger is it going...

All particles belong to two large groups: fermions like protons and electrons make everything we consider "matter", while bosons like photons and...

Warp drives may or may not be possible, but if they are then could a distant alien civilization’s warp fields produce gravitational waves that...

Nobel laureate Roger Penrose is widely held to be one of the most brilliant living physicists for his wide-ranging work from black holes to...

The primary characteristic that defines black holes is in the name. Black holes are black. The gravitational pull at the event horizon is so powerful...

Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered some...

The holy grail of theoretical physics is to find the long-sought theory of quantum gravity. But what if this theory is as mythical as the grail of...

If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple theories that claim...

If you track the motion of individual stars in the ultra-dense star cluster at the very center of the Milky Way you’ll see that they swing in...

Here’s the story we like to tell about the beginning of the universe. Space is expanding evenly everywhere, but if you rewind that expansion...

We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard...

Neutron stars aren't dark matter--we figured that out a while ago. But new research is telling us that they may be dark matter factories. They may...

Imagine a world where humanity masters every planetary resource available to it—our first step on the famous Kardeshev scale of technological...

There are cosmic events so powerful that they leave permanent marks on the fabric of the universe itself. Imagine two colossal black holes spiraling...

Every good nerd knows that E=mc^2. Every great nerd knows that, really, E^2=m^2c^4+p^2c^2 Want to know what that even means? Sure, I’ll tell...

Is there a limit to how much energy you can cram into, or pull out of one patch of space? Well, we thought so, but the James Webb Space Telescope has...

What does an electron really look like? I mean, if we zoom in all the way. Is it a sizeless speck of charge? Is it a multidimensional vortex of...

What do you get if you take something that’s infinitely massive and combining with something else that’s negative infinitely massive? You...

Engineering enthusiasts battle to create the most ingenious contraption using everyday objects. Teams are challenged to fabricate and demonstrate a...

From the planets to the stars and out to the edge of the unknown, history and science collide in a wondrous yet deadly adventure through space and...

Explore the impact of A.I. and how it is transforming the way we live and work -- both now and in the future, featuring some of the brightest minds...

Hawking gives us the ultimate guide to the universe, a ripping yarn based on real science, spanning the whole of space and time -- from the nature of...

Join Stephen Hawking and other renowned thinkers as they explore the revolutionary new ideas that have evolved since the publication of his...
