They may have arisen less than 200 million years after the Big Bang, but the Universe was a very different place back then. When you look out beyond the Milky Way […]

In a breakthrough for nuclear fusion research, scientists at China’s Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.
Every object in the Universe is constrained by the laws of physics. Does this mean there are any black holes that shouldn’t exist? When it comes to the objects that […]
If you think you have problems today, be glad you’re not moving at the speed of light. Special relativity, even though it’s over 100 years old, is still one of the […]
It’s a rare occasion for orbits to align so perfectly. Enjoy the sights this Tuesday. On Tuesday, February 19th, the Moon will reach perigee, its closest point of approach to planet […]
As one of the biggest manmade structures in the sky and at a cost of over $100b, it’s the place where the space age dream is still alive.
The line between science and pseudoscience is imperceptible to most. Here’s how you can catch it in yourself. When it comes to science, the first principle is that you must […]
Jim Peebles, Michel Mayor and Didier Queloz just won the 2019 Nobel Prize in Physics. It couldn’t be more well-deserved. Every year, the Nobel Prize reminds all of humanity to […]
The hallmark of a good scientist is changing your mind when new evidence arises. Here’s what that looks like. Science, like many things in life, is always a work-in-progress. While a […]
Doomsday prophesies have never once come to pass, but they’ve never had science on their side like this before. Every year, the Earth completes an orbital revolution around the Sun, returning […]
The result validate Einstein on a whole new scale, and pose serious problems for alternative, modified theories of gravity. In 1915, Albert Einstein put forth a new theory of gravity: General […]
Astronauts aren’t floating in space, they’re free falling—and so are you. Here’s the amazing science behind so-called zero gravity.

In 2015, Ed Witten, the greatest living string theorist, wrote a piece on why. Here’s the version for everyone. It’s one of the most brilliant, controversial and unproven ideas in […]
Famous inventors and scientists submission to the daily grind
The dream of multi-messenger astronomy is to seen an event with gravitational waves, neutrinos, and light all together. The newest candidate just might get us there. When it comes to cataclysmic […]
If spacetime is like a fabric, and mass bends it, what flattens it back out again? Matter tells space how to curve, and curved space tells matter how to move. That’s […]
Our planet is rare, precious, and fragile. It’s up to all of us to be its steward. With the advent of rocketry and spaceflight, our cosmic perspective changed forever. The very […]
Our motion through space is undeniable. So why can’t we feel it? Our planet isn’t the stationary place we feel it to be beneath our feet, but rather moves in an […]
Even if we don’t destroy ourselves, we always have the Universe to contend with. Wiping out all life on Earth is hard, but causing mass extinctions is easy. The 1991 eruption […]
After Kepler but before James Webb, TESS is preparing astronomers for the coming exoplanet revolution. There are always new discoveries and achievements occurring in science, and certain fields have experienced […]
If you accept cosmic inflation and quantum physics, there’s no way out. The Multiverse is real. Look out at the Universe all you want, with arbitrarily powerful technology, and you’ll never […]
What happened 4.56 billion years ago is the most important part of the cosmic story ever to happen to us. If you were to look at our Universe at the time […]
For perhaps 100 million years, there were no stars in the Universe. What was it like then? The earliest stages of the Universe were extraordinarily eventful in bringing us about. Cosmic […]
There are rules absolutely forbidding it from happening. But some particles do it anyway. All the matter we know of in the Universe is made up of Standard Model particles. Photons […]
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, […]
Feel like traveling to another dimension? Better choose your black hole wisely.
The eruption quickly killed those caught in its intense wake.
NASA’s Cassini spacecraft taught us more than we ever imagined about Saturn. Could we do something similar for Uranus and Neptune? From where we are in the Solar System, looking out […]
We often think only of grown ups taking pills, this study reminds us children can take them too.
The world’s greatest clockmaker sent a clock to the new world, and everything went haywire. The reason why will shock you. For millennia, humanity’s one-and-only reliable way to keep time was […]
