Physics

Unlike most articles that are titled with a question, the answer isn’t automatically “no.” Announced on January 6, 2020, NASA’s TESS mission has just discovered its first Earth-sized, habitable zone […]
The images themselves will take your breath away, but the science we can extract from them is truly revolutionary and spectacular. Dark matter may be one of the most mysterious […]
It’s a pipe dream that violates the laws of physics, and not even quantum mechanics can give us a way out. One of the most fundamental rules of physics, undisputed since […]
It’s a supergiant star in the final stage of its life, and it just dimmed by an enormous amount. What’s going on? When you take a look at the stars in […]
We all have obstacles to overcome in pursuit of our goals. For Santa Claus, it’s clear that science is the key. Of all the challenges we face in our work, perhaps […]
A fascinating mathematical structure exists that goes well beyond our common experience. Could it revolutionize physics? Perhaps the most remarkable fact about the Universe is that every particle within it — at […]
The hot Big Bang occurred 13.8 billion years ago, and there’s no other possible answer consistent with what we know today. Conceptually, it might seem like the simplest idea in existence […]
We speak with cosmologist Dan Hooper, and ponder the literal edge of what we know about the Universe. Have you ever wondered what the first moments of our Universe were […]
Even extremely simple configurations in General Relativity cannot be solved exactly. Here’s the science of why. It’s difficult to appreciate how revolutionary of a transformation it is to consider the Universe […]
If this discovery came in a pre-LIGO era, maybe it would have been a surprise. But in 2019, there’s no mystery at all. Did you hear that astronomers had recently […]
In science, breakthroughs don’t always begin with a ‘eureka’ moment. Sometimes, the true story is absolutely unbelievable. When it comes to our Universe’s origin story, many competing ideas once thrived. […]
If an AT-AT walker (or something even larger) wanted to walk across a frozen lake, how thick would the ice have to be? Each winter, one of the most spectacular phenomena […]
The Leonid meteor shower peaks today. Its parent comet taught us where meteor showers come from. Every year, as Earth regularly orbits the Sun, meteor showers repeatedly recur. While August’s Perseids […]
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 […]
When you hear ‘quantum,’ you probably think of splitting everything into discrete, indivisible chunks. That’s not necessarily right. If you want to learn what the Universe is made out of […]
If you think about the way a gravitational wave detector works, you might encounter a paradox. Here’s the solution. One of the greatest scientific achievements in all of human history […]
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 […]
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 […]
Traveling interstellar distances in human lifetimes is an amazing dream, but it won’t ever be achieved like this. For centuries, ever since we realized that every star we can see in […]
If you think that the Moon is only good for reflecting sunlight, you’ve got another think coming. To human eyes, the Moon is the second brightest visible object, trailing only the […]
Many deserving potential awardees were snubbed by the Nobel committee. But this takes the cake. Every October, the Nobel foundation awards prizes celebrating the greatest advances in numerous scientific fields. Alfred […]
It’s not about whether speculating theorists are right; it’s about looking where humanity has never looked before. The Large Hadron Collider, located at CERN, is the most powerful particle accelerator and […]
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 […]
As soon as you start thinking about energy and gravity, you’ll realize the need to go beyond it. When it comes to a science like physics, theoretical expectations must always be […]
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 […]
It’s perhaps the most famous equation of all, with lessons about reality for every one of us. If you’ve ever heard of Albert Einstein, chances are you know at least one […]
Many of them are spinning at nearly the speed of light. When you do the math, there’s no other way it could have been. Take a look out there at the […]
When you’re trying to peel back the veil obscuring the fundamental nature of matter, you have to look absolutely everywhere. Sometimes, the solution to a puzzle you’ve been stymied by […]
General Relativity has nothing to do with light or electromagnetism at all. So how to gravitational waves know to travel at the speed of light? There are two fundamental classes of […]
From explosions to their unique and vibrant colors, the fireworks displays we adore require quantum physics. This Thursday, July 4, 2019, is remarkable for a number of reasons. It happens to […]
