In the middle of a great cosmic void, a single, isolated galaxy persists amidst the darkness. It’s about to get a lot lonelier. Here in our own cosmic backyard, the […]
We can go to deeper and deeper levels, finding more fundamental quantities as we do. But is there a truly fundamental quantity? What is the Universe, at a fundamental level, […]
Red, green, and blue? What we call ‘color charge’ is far more interesting than that. At a fundamental level, reality is determined by only two properties of our Universe: the quanta […]
These photos of scientific heroes and accomplishments inspire awe and curiosity.
Just because you can design an experiment to test for something doesn’t mean you should trust the results. Is there another Universe out there? The Universe we know and inhabit, the […]
From the inflationary state that preceded the Big Bang to our cold, lonely, dark energy-dominated fate, the Universe goes through six different eras. We’re living in the last one already. The […]
Synthetic biology is changing the way the planet works.
To explain the origin of everything, science needs to explain itself.
Somehow, the Universe began with just the right mix of cosmic ingredients to make life possible. It sure doesn’t seem likely. When you take stock of what’s in the Universe on […]
Cognitive psychologist Donald Hoffman hypothesizes we evolved to experience a collective delusion — not objective reality.
Despite what Hawking told you, it really isn’t about particle-antiparticle pairs at all. Nothing in the Universe lives forever. All the stars that will ever form will someday burn out; distant […]
With the right material at the right temperature and a magnetic track, physics allows you to never lose energy. The idea of levitating off the ground has been a staple of […]
Many people, including some scientists, fear that the coming 5G WiFi revolution will harm humans. Here’s why that’s unfounded. Over the coming few years, a new set of infrastructure will […]
Results are among the strongest evidence yet for “spooky action at a distance.”rnrn
For decades, one of the Big Bang’s greatest predictions was shrouded in doubt. The answer was always there on Channel 3. When it comes to the question of how our Universe […]
And if the data is good enough, we can determine that it’s accelerating directly, too, silencing the last remaining doubters. If you want to understand what the Universe is made […]
Do you have a magnetic compass in your head?
The coin depicts a black hole and one of the late physicist’s most important formulas.
Not building one means giving up on brute force. We’re not yet ready to do that. There’s a problem with the field of high-energy physics, and it’s the biggest one imaginable. […]
It’s exotic, incredibly cold stuff.
100+ years ago, General Relativity came along, and Einstein gave the Universe a cosmological constant. Here’s why that was a mistake. Back in the 17th century, Isaac Newton put forth the […]
Theoretical work tells you where to look, but only experiments can reveal what you’ll find. There are fundamental mysteries out there about the nature of the Universe itself, and it’s our […]
If we find the earliest signal from the Universe’s birth, how can we be sure we aren’t fooling ourselves? When it comes to the origin of the Universe, the Big […]
Even though it was the crowning achievement of Einstein’s career, he was only a small part of the full story. If you were a physicist in the early 20th century, there […]
Some of the world’s most prestigious universities aren’t in America.
