The first image of an Event Horizon is here. Here’s what it means. Variety isn’t just the spice of life, but a natural consequence of living in our Universe. Gravitation, obeying […]

The expanding Universe really is accelerating, and no dusty scenario can explain it. 20 years ago, our understanding of the Universe underwent a revolution. For generations, we had known the Universe […]
When scientists claim that an unexplained phenomenon might be due to aliens, they’re giving up on science. Whenever science discovers a new, unexpected phenomenon, it represents a tremendous opportunity to learn […]
It’s the ultimate way to go… and yet, it still isn’t what you’d expect. There are many terrifying ways that the Universe can destroy something. In space, if you tried to […]
When you have the opportunity to take gravity away from the human body, the results are pretty fasninating.

Two of our biggest science-fiction dreams might not remain fiction for much longer. Here’s how 21st-century science could make it real. For as long as human beings have looked up at […]
To explain the origin of everything, science needs to explain itself.
It might seem puzzling, in a Universe bound by the speed of light, that this could be true. Here’s the science behind it. If you look out into the distant Universe, […]
And do they fundamentally describe our entire Universe, or do we require something else? The Universe we perceive and view, all around us, isn’t representative of what actually exists at […]
If our current laws of physics can’t predict what will happen, even probabilistically, we need something new. There are two theories we have that explain all the particles and their […]
Faraday’s law of induction was set forth in 1834, and was the experiment that led Einstein to discover relativity. When we think about Einstein and the theory of relativity, all […]
A theory from cosmology claims the Universe could rip apart to shreds.
When we split something into its most fundamental, indivisible components, are we truly seeing something that’s point-like, or is there a finite minimum size? Imagine that you wanted to know what […]
A new study may change the face of astrophysics.
Who would prefer a 30-hour work week? A lot of people, it turns out.
Venus: Hot, toxic, hellish… home?
If you look everywhere between the numbers 1 and 2, you’ll never find 3. Let’s say you have an idea about how our physical reality might be different from how we […]
The Flynn effect shows people have gotten smarter, but some research claims those IQ gains are regressing. Can both be right?
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 […]
She’s not a scientist, an expert, or even an adult. But she’s got one good lesson to teach us all. Like most people on Earth, Greta Thunberg is not a climate […]
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 […]
These cosmic behemoths were enormous from very early times. Here’s how they came to be. One of the biggest challenges for modern astrophysics is to describe how the Universe went from […]
If we don’t push the frontiers of physics, we’ll never learn what lies beyond our current understanding. At a fundamental level, what is our Universe made of? This question has […]
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 […]
Every physical theory has constants in it. The gravitational constant is remarkably uncertain. When we first began formulating physical laws, we did so empirically: through experiments. Drop a ball off […]
Dark matter feels fake. MOND sounds plausible. What should you conclude? Imagine I told you that everything you ever saw, touched, or experienced — in this world and in the Universe beyond — was […]
If they saw us as we were before the recent industrial revolution, would there be any reason to particularly care about us? All across the Universe, trillions of galaxies can be […]
Earth wasn’t the only potentially habitable planet in the early Solar System. What happened to Mars? If you could travel back in time to the early stages of the Solar System, […]
