Why is there something rather than nothing? Well the answer may be found in the weakest particle in the universe: the neutrino. For over half a...

Black holes are awesome - but how about black holes being captured by the screaming vortex of a quasar, where they merge and grow like some monstrous...

The three body problem is famous for being impossible to solve. But actually it's been solved many times, and in ingenious ways. Some of those...

In particle physics we try to understand reality by looking for smaller and smaller building blocks. But what if that has been the wrong philosophy...

If the universe goes on forever, does that mean there are infinite versions of you out there?

What does the strong nuclear force, the fundamental symmetries of nature, and a laundry detergent have in common? They’re all important parts...

It’s not surprising that the profound weirdness of the quantum world has inspired some outlandish explanations - nor that these have strayed...

Why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many...

If we can’t ever peer into these other realities that are used to explain quantum mechanics, how do we know they exist? In order to understand...

In quantum world things are routinely in multiple states at once - what we call a “superposition” of states. But in the classical world...

If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators,...

Normal maps are useless inside black holes. At the event horizon - the ultimate point of no return as you approach a black hole - time and space...

In astronomy we talk about billions of years like it’s no big deal. But how can we be sure about timescales so far beyond the capacity for...

The Milky Way galaxy is relatively calm by the destructive standards of the rest of the Universe, and compared to its own very violent past. But just...

From Stargate to Interstellar, wormholes are our favorite method for traveling across fictional universes. But they are also a very serious field of...

The universe is precisely 13.8 billion year old - or so our best scientific methods tell us. But how do you learn the age of the universe when...

As the 19th century came to a close, physicists were feeling pretty satisfied with the state of their science. The great edifice of physical theory...

This is a map of the multiverse. Or in physics-ese, it’s the maximally extended Penrose diagram of a Kerr spacetime. And in english: when you...

It’s been 120 years since Henry Cavendish measured the gravitational constant with a pair of lead balls suspended by a wire. The fundamental...

With the global pandemic of Covid 19 still encompassing the word, we are generally not big fans of viruses right now. But we sure are thinking about...

Conformal Cyclic Cosmology is a story of the origin and the end of our universe from great mathematical physicist Sir Roger Penrose. It’s goes...

Black holes are about the worst subjects for direct study in the universe. But at this stage, it’s all we can do to convince ourselves of their...

Black hole singularities break physics - fortunately, the universe seems to conspire to protect itself from their causality-destroying madness. At...

The most precious substance in our universe is not gold, nor oil. It’s not even printer ink. It’s antimatter. But it’s worth every...

When we detected the very first gravitational wave, a new window was opened to the mysteries of the universe. We knew we’d see things...

Our galaxy is full of dysfunctional stellar relationships. With more than half of all stars existing in binary orbits, it’s inevitable that...

If you wanna make an omelet you gotta break a few eggs. And by omelet I mean a theory of everything, and by eggs I mean a billion billion subatomic...

Pin-pricks in the celestial sphere, through which shines the light of heaven? Or gods and heroes looking down from their constellations? Or lights...

The great physicist Hermann Weyl once said: "My work always tried to unite the true with the beautiful, but when I had to choose one or the other, I...

One of the most bizarre proposals for life not as we know it doesn’t even use atoms. It proposes that fundamental kinks and defects in the...

Your extensive posting history on r/birdswitharms and your old fanfiction-heavy livejournal are both one tiny math problem away from becoming public...

If you rank the most habitable places in our solar system Venus lands pretty low, with surface temperatures hot enough to melt lead and sulphuric...

Is all that exists just whatever exists right now? Is the past erased and the future a void yet to be filled? Well, the answer lies in between the...

Einstein’s special theory of relativity combines space and time into one dynamic, unified entity - spacetime. But if time is connected to...

The Nobel prize in physics this year went to black holes. Generally speaking. Specifically, it was shared by the astronomers who revealed to us the...

Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces. But...

Physicists have a long history of sticking our noses where they don’t belong - and one of our favorite places to step beyond our expertise is...

Ever wish you could travel backward in time and do things differently? Good news: the laws of physics seem to say traveling backward in time is the...

The laws of physics don’t specify an arrow of time - they don’t distinguish the past from the future. The equations we use to describe...

Good news everyone: it looks like the universe is going to end with a series of catastrophic explosions. The very, very long story short is that the...

We often think of quantum mechanics as only affecting only the smallest scales of reality, with classical reality taking over at some intermediate...

The Bell System Science Series consists of nine television specials made for the AT&T Corporation that were originally broadcast in color between...

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

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...
