Examine life’s biggest questions, from ethics to existence, with curiosity and critical thinking.
We assume that life is ubiquitous in the Universe. But what if it’s just us? When it comes to the question of extraterrestrial life, humans optimistically assume the Universe is prolific. […]
If dark energy is causing the Universe to disappear, how can we still find and see ultra-distant stars and galaxies? In the 1920s, scientists discovered that the Universe was expandingbased […]
The transition across a quantum barrier is known as quantum tunneling, and the amount of time it takes for such a transition to occur had never been measured before. For […]
If you’re careful enough, you can learn more about the Solar System than you ever imagined. This year, on March 20th, the full Moon will illuminate the night sky. With […]
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 […]
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 […]
Yes, life exists in our Universe. No, that statement doesn’t equal science. Imagine you’ve encountered a natural phenomenon you want to understand better, but don’t have the tools to do so. […]
For billions of years, dark energy couldn’t have been detected. Now, it’s everywhere we look. When we look out at the ultra-distant Universe, billion of light-years away, we’re seeing it as […]
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 […]
The heaviest elements in the periodic table have their own unique story. No, they don’t come from a supernova. When it comes to the elements of the Universe, every one […]
Whether you caught or missed the eclipse of January 20/21, 2019, here’s what you need to know for all the ones you’ll ever view again. On January 20/21, 2019, a very […]
The ability to instantaneously jump from one location in space to another clearly violates the laws of physics. Or does it? There are a few rules in the Universe that seem […]
The Earth is getting warmer, and humans are the cause. This is why. Let’s play pretend for a moment. Pretend, if you can, that you’ve never heard about the idea of […]
With 1.6 billion households in the world, how does Santa do it? With a little Christmas magic… and a lot of science! How does Santa Claus do it? In one long […]
It’s okay to be skeptical. That’s why we have evidence. In all of human history, only 24 people have ever flown to the vicinity of the Moon, traveling hundreds of […]
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 […]
The first planets were only gas. The second included rocky ones, but life wasn’t possible. Here’s how we finally got there. Here in the Universe today, potentially habitable planets are practically […]
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, […]
If particles weren’t also waves, the Sun would never achieve nuclear fusion. Without quantum mechanics, life on Earth would never have come to exist. The greatest source of newly-produced energy in […]
At ground zero, Trinitite, the green, glassy substance found in the area, is still radioactive and must not be picked up. The Trinity Site was where the first atomic bomb […]
