They say that atoms are mostly 99.99999% empty space. But quantum physics says otherwise. If you were to look at what your body is made of, at smaller and more […]

The images and our best computer models don't agree.
Scientists used CT scanning and 3D-printing technology to re-create the voice of Nesyamun, an ancient Egyptian priest.
The expansion rate is dropping, but distant galaxies are accelerating. Here’s how. If you take a look at any galaxy in the Universe that isn’t gravitationally bound to our own, we’ve […]
Here are the best answers science has to a myriad of commonly asked questions. Over the past 12 months, the status of humans on planet Earth has changed dramatically. The […]
How a controversial study on psychic powers caused a revolution in psychology research.
Map shows oldest buildings for each U.S. state – but also hints at what's missing.
Complex organisms and living worlds couldn’t exist without these transitions. You couldn’t make the Universe we have today if everything were always the same. Although many philosophically favored the idea […]
It’s fundamentally different from space. Here’s how. Here’s a question that most of us have been asked at some point in our lives, “what’s the shortest distance between two points?” By […]
The double-slit experiment, all these years later, still holds the key mystery at the heart of quantum physics. When we divide up matter into the smallest possible chunks that it’s made […]
It doesn’t propagate at infinite speeds, and that’s a problem for Newton. When you look at the Sun, the light you’re seeing isn’t the light that’s being emitted right now. Instead, […]
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 […]
Unbelievably enough, it all comes back to Pythagoras. One of the first theorems anyone learns in mathematics is the Pythagorean Theorem: if you have a right triangle, then the square […]
How can we save humanity from ourselves? In this life and this Universe, there will always be questions beyond the capabilities of humanity to answer. There’s so much that we’ve […]
The first Earth-sized planet without a parent star has just been discovered. For countless millennia, planets beyond our Solar System were mere speculation. Today, we know of over 4,000 confirmed […]

Two stellar mass black holes, if they merge in the vicinity of a supermassive black hole, could have their gravitational wave signal affected by the strongly curved space around them. […]
Could this finally be the clue we’ve hoped for in uncovering the truth about dark matter? In the physical sciences, theory and observation are supposed to work hand-in-hand. Theorists work out […]
We might live in a quantum Universe, but we’ll violate the principle of relativity if space is discrete. If you try and divide matter into smaller and smaller chunks, you’ll […]
Using atoms to probe the Universe reveals the complete Standard Model. If you wanted to uncover the secrets of the Universe for yourself, all you’d have to do is interrogate […]
If the electromagnetic and weak forces unify to make the electroweak force, maybe, at even higher energies, something even greater happens?
It doesn’t have to be a science-fiction dream. For as long as human beings have been watching the night sky, we’ve dreamed of visiting other worlds and truly seeing what’s […]
Delaying or refusing vaccines for non-medical reasons is literally a killer choice. When it comes to issues at the intersection of science and society, there are all sorts of things that […]
Of all the injustices in Nobel Prize history, her 1957 Nobel snub is the most egregious. One of the biggest scientific revolutions of the 20th century was the discovery of […]
The inevitable long, slow decline is accelerating, and there’s nothing we can do. The Universe, as it is today, is less active, is forming fewer stars, and is creating fewer chances […]
The Universe’s idea of a ‘typical star’ has changed dramatically over time. When you look out at the Universe today, you’re not seeing it exactly as it is at one particular […]
The Universe, according to our best understanding, just doesn’t add up. The Universe, according to our best understanding, just doesn’t add up. Wherever we look — from tiny subatomic scales all the way […]
California’s Bobcat Fire has reached Mount Wilson Observatory’s doorstep. 100 years ago, our understanding of the Universe was very different from what it is today. Einstein’s General Relativity, our theory […]
All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
We still don’t know how the information encoded onto it gets out. No matter what you do in the Universe, its overall entropy always increases. Even when we put things in […]
