Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
100+ years ago, General Relativity came along, and Einstein gave the Universe a cosmological constant. Here’s why that was a mistake. Back in the 17th century, Isaac Newton put forth the […]
It’s been spectacularly confirmed by observation, but theoretically, it couldn’t have been any other way. If the Sun were to spontaneously cease emitting light, we wouldn’t know about it for about […]
If this newfound galaxy is just the tip of the iceberg, the entire Universe may fall into place. One of the greatest challenges for a scientist is that every time you […]
The origin story for our Universe got a major revision nearly 40 years ago. Time to catch up. 13.8 billion years ago, all the matter and energy contained within our Universe […]
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 […]
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 […]
Simply getting into grad school isn’t enough. The answers to these three questions can make all the difference. It’s time. You’ve done all your research into schools, completed your undergraduate […]
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 […]
If you think that the Moon is only good for reflecting sunlight, you’ve got another think coming. To human eyes, the Moon is the second brightest visible object, trailing only the […]
It’s much more complex a question than dividing its mass by the volume of the event horizon. If you want to get a meaningful answer, you have to go deep. If […]
There’s an enormous evolutionary advantage for flamingos to stand on one leg, but only physics explains why. Of all the natural marvels unique to planet Earth, the diversity of the living […]
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 […]
It’s not about whether speculating theorists are right; it’s about looking where humanity has never looked before. The Large Hadron Collider, located at CERN, is the most powerful particle accelerator and […]
A recent headline claimed they could. But if gamma-rays are just a form of light, don’t they have to travel at light-speed? There’s an ultimate speed limit in the Universe: […]
Even though it was the crowning achievement of Einstein’s career, he was only a small part of the full story. If you were a physicist in the early 20th century, there […]
We know a lot about what else is out there, but we still don’t know everything. In the quest for life in the Universe, it makes sense to look at […]
There’s so much we don’t know about fast radio bursts and galactic halos. Combined, we get a unique window on the Universe. Deep in space, mysterious signals known as Fast […]
A fully programmable quantum computer that can outperform any classical computer is right at the edge of today’s technology. Earlier this month, a new story leaked out: Google, one of […]
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 […]
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 […]
