It’s often said that every element was made in a star, but there’s more to it than that.
If you understand gravity well enough, you might not even need a telescope to revolutionize astronomy. In science, advances arise at the intersection of theory and real-world observation. One of […]
The Red Planet, the God of War, and important life lessons for us all.
Hubble has been operational for nearly 30 years, and still produces the most spectacular images of all. Here are this year’s best. Hubble, astronomy’s revolutionary observatory, narrowly survived last year’s gyroscope […]
Matter can indeed sprout out of nothingness, causing the universe to expand.
Hawking radiation should really be happening, but black holes are farther from decaying than ever before. Black holes are, in many ways, the most extreme objects that will ever exist in […]
If parallel Universes or the multiverse are real, we might someday encounter a visitor who hails from another one. Here’s what to do. There are a lot of things that are […]
In the mid-20th century, ‘physical cosmology’ was considered an oxymoronic joke. Today, it’s Nobel-winning science. Imagine you wanted to know everything you could about the Universe. You’d want to find […]
There are places in our solar system where you can fly.

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 […]
When you emit gravitational waves, they have to pass through the Universe. But do they gravitate, too? When you travel through the Universe, it isn’t just a free ride through […]
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 […]
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 […]
They experience reality differently than we do.
NASA astronomer Michelle Thaller will be at Big Think’s studio on May 16th to answer YOUR questions! Here’s all you need to know to submit your science-related inquiries.

The flying rotorcraft drone is set to land on Saturn’s largest moon in 2034.
We’ve put so much together about the Universe. Could it all come tumbling down? We’re always on the lookout for the next big thing, and even our best guesswork is often […]
It’s one of cosmology’s biggest unsolved mysteries. The strongest argument against it may have just evaporated. The ultimate goal of cosmology contains the greatest ambition of any scientific field: to […]
Gravity gets weaker as the distance squared. But gravitational waves only get weaker as the distance. Why? One of the things we often just accept about the world is that […]
Elon Musk took issue with recent ideas for space exploration from Jeff Bezos.
Einstein’s explanation is the only one that works. When Newton first proposed the law of universal gravitation, it marked the very first time that we realized the same rule governing how […]
Documentary explores astrobiology, astronauts, and the awe of it all.

When the supernova occurs, a whole slew of signals will arrive at once. But there’s one hint that could successfully warn us in advance. As Betelgeuse continues to vary in brightness […]
It’s been over 100 years since Einstein, and over 300 since Newton. We’ve still got a long way to go. From measuring how objects fall on Earth to observing the motion […]
The Apollo 11 astronaut was recently awarded the Stephen Hawking Medal for Lifetime Achievement.
When it comes time for humanity to pick a new home, where will we go?
And why Einstein’s quest for unification was doomed from the start. If you wanted to answer the question of what’s truly fundamental in this Universe, you’d need to investigate matter and […]
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 […]
We’ve never seen an image of a black hole’s event horizon before. Here’s what we’re expecting, based on what we already know. For hundreds of years, physicists have hypothesized that the […]
