The view from way out there really puts things in perspective.

It’s been spectacularly confirmed by observation, but theoretically, it couldn’t have been any other way. If the Sun were to spontaneously cease emitting light, we wouldn’t know about it for about […]
If we could see in three dimensions instead of two, we’d never have thought otherwise. Perhaps the most famous sight of a dying star is the Ring Nebula, discovered in […]
The light we observe isn’t the same as the light that gets emitted. Here’s what causes it. The light you see, when you look out at the stars and galaxies that […]
A study at the University of Oregon puts a longstanding myth to rest.
A mind-bending physics theory may explain why we have one reality instead of many.
If economic growth knowingly increases mass-scale suffering, can we stop chasing it?
Black holes are regions of extreme gravity, but dark matter barely interacts at all. Do they play well together? Black holes are some of the most extreme objects in the […]
There are a lot of unsolved mysteries in the Universe, but dark energy is the most confusing. Here’s why. The majority of the energy in our Universe went completely undiscovered until […]
Astrophysics has probed a test of a fundamental law, ‘Lorentz invariance,’ well beyond the LHC’s limits. Einstein is still right. The greatest scientific legacy that Albert Einstein left us is this: […]
The Planck length is a lot smaller than anything we’ve ever accessed. But is it a true limit? If you wanted to understand how our Universe operates, you’d have to examine […]
Immigrants add way more to the American economy than they take.
You might think that we live in a three dimensional Universe based on space alone. But you cannot leave time out of it. If you were asked to describe how you […]
There’s real, straightforward science behind the destruction of an Alderaan-sized planet. In all of science fiction, perhaps the most iconic moment of destruction occurs in 1977’s Star Wars: A New […]
No one has seen an equinox this early since the 19th century. And you’d better get used to it. This year, on March 19, 2020, the equinox will occur. For a […]
Remembering a 1972 symposium gathering of the world’s greatest physicists.
It’s not impossible according to physics, but we truly don’t know how this object came to exist. Out in the extremities of the distant Universe, the earliest quasars can be found. […]
Few scientific ideas have been as polarizing as string theory. There are good reasons to both love it and hate it. String theory is perhaps the most controversial big idea in […]
They experience reality differently than we do.
The farther away they get, the smaller distant galaxies look. But only up to a point, and then they get magnified. Here’s how. Intuitively, we all know that when we see […]
Stronger than the LHC and faster than anything except light, the world’s cleverest particle detector sees the particles we could never create on Earth. It might be true that there’s an […]
The small step that one man took would never have happened without this narrow escape. On July 20, 1969, history was made as humanity set foot on the Moon for the […]
Want to eat better but feel like you don’t have the money?
The discovery could lead to improved treatments for chronic pain.
Observations have been ruined; scientific satellites with the right-of-way have had to alter course. Here’s a how-to guide to doing better. In any field of business or industry, the prevailing rule […]
What strategies do you use to push through a tough challenge, be it a run on a treadmill or a stressful phone call with your boss? Perhaps you remind yourself […]
Our Universe cannot be described by normal matter alone. Vera Rubin’s work led the way. Ask an astrophysicist what our Universe is made of, and you’ll likely receive a shocking surprise. […]
