At just 3 solar masses, it eliminates the “mass gap.” Searching for black holes is one of the most difficult astronomical games a scientist can play. Emitting no light of their […]
Can quantum computers do things that standard, classical computers can’t? No. But if they can calculate faster, that’s quantum supremacy.
Despite the Sun’s high core temperatures, particles can’t quite overcome their mutual electric repulsion. Good thing for quantum physics!
When the average person has a “theory,” they’re just guessing. But for a scientist, a theory is the pinnacle of what we can achieve.
A well-known psychology trick called the “rubber hand illusion” could be useful for treating patients with obsessive-compulsive disorder.
The Universe isn’t just expanding, the expansion is also accelerating. If that’s true, how will the Milky Way and Andromeda eventually merge?
You don’t need to ride into the danger zone to take advantage of TOPGUN’s life and career lessons.
Travel half the distance to your destination, and there’s always another half to go. Despite Zeno’s Paradox, you always arrive right on time.
Scientists put the most mysterious force in the Universe to the ultimate test. When it comes to the Universe, it’s easy to make the incorrect assumption that what we see is […]
Metal really does sometimes stick to some people’s skin. Here’s the science of why. Every once in a while, a claim comes along that wildly challenges the mainstream scientific narrative. These […]
Success can be measured in different ways. When it hinges entirely on our careers, we fall victim to a devastating addiction.
When we satisfy our curiosity, the brain has a particular way of rewarding us.
Some scientists believe that DMT could revolutionize the treatment of depression.
How quickly is it expanding today, and how does that expansion rate change over time? What is the Universe made of? How quickly is it expanding today, and how does that […]
There are many theories of gravity out there, and many interpretations of wide binary star data. What have we really learned from it all?
Dr. Tyson explains where we might find aliens, why “dark matter” is a misleading term, and why you can blame physics for your favorite team’s loss.
The smallest and faintest stars of all, even the failed stars that didn’t make it, are hiding some fascinating secrets. You might have thought that if we were going to […]
The highest-energy particles could be a sign of new, unexpected physics. But the simplest, most mundane explanation is particularly iron-ic.
65 million years ago, an asteroid strike caused the 5th great mass extinction. Could we save Earth, today, from a similar event?
It turns out, letting your partner know you appreciate them leads to a stronger relationship. Who’d have thunk?
When the Universe was first born, the ingredients necessary for life were nowhere to be found. Only our “lucky stars” enabled our existence.
Yes, “the laws of physics break down” at singularities. But something really weird must have happened for black holes to not possess them.
Even 13.8 billion years after the Big Bang, we can reconstruct the first 3 minutes. About 100 years ago, we began to truly understand the nature of the Universe for the […]
Although human beings arrived on Earth just ~300,000 years ago, we’ve transformed the entire planet completely. Here’s how we did it.
Nobel Laureate Roger Penrose, famed for his work on black holes, claims we’ve seen evidence from a prior Universe. Only, we haven’t.
In Sun-like stars, hydrogen gets fused into helium. In the Big Bang, hydrogen fusion also makes helium. But they aren’t close to the same.
Measuring a person’s movements and poses, smart clothes could be used for athletic training, rehabilitation, or health-monitoring.
With JWST, Chandra, and gravitational lensing combined, evidence has emerged for the earliest black hole ever. And wow, is it a surprise!
The first world that humans should inhabit beyond the Earth is the Moon, not Mars. Here’s why terraforming our lunar neighbor is so appealing.
