Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
BICEP2 scientist Brian Keating’s new book is honest and insightful, but just as notable for what it fails to recognize. Imagine what it’s like to be a scientist working on […]
In the aftermath of everything we’ve learned about what’s in the Universe, we can make much better estimates of how many alien civilizations are out there. In 1961, scientist Frank Drake […]
Even with nothing new falling into it, our radius is increasing with every second that goes by. It’s no big secret that galaxies grow over time. The force of gravity is […]
The paradox is one that Hawking himself claimed to have a solution to many times, but none of the proposals have held up to scrutiny. The paradox is still unresolved. […]
The same technology that Norway uses to keep its fjords ice-free could literally take the power out of hurricanes as they form. Among all the natural disasters that occur on planet […]
Congress refused the majority of Trump’s proposed cuts to NASA’s budget. But many uncertainties remain. On March 21st, 2018, both branches of Congress passed the United States’ Consolidated Appropriations Act, […]
If everything was hot, dense, and super close-together at the Big Bang, what kept us from collapsing into a singularity? The Big Bang is one of the most counterintuitive ideas […]
Ever hear of Hawking radiation? Or the black hole information paradox? Time to get your fix! In memory of Stephen Hawking’s life, I’ve decided to share the physics behind his greatest […]
In 2016, the number of opioid-related deaths hit 42,000, an all-time record. But gun deaths were nearly that same number, and have been consistently that high. If you want to know […]
With hundreds of billions of stars burning bright, ‘dead’ seems like a bit of an exaggeration. But every galaxy is headed for this fate, including ours. As long as a […]
Even our scientific heroes can’t be right about everything. Let’s learn the lessons that they never did. In the 1960s, a young theoretical physicist named Stephen Hawking rose to prominence as […]
For every planet that orbits a star like our own, there are likely thousands of ‘orphan planets’ wandering the galaxy alone. Here in the Solar System, we can watch our star’s […]
One of the three basic circuit elements just got a lot smaller for the very first time, in what promises to be a trillion-dollar breakthrough. In the race for ever-improving […]
There have been a lot of public advocates from the “no dark matter” camp, getting lots of popular attention. But the Universe still needs dark matter. Here’s why. If you took […]
For most of us, it’s something we just accept every year. But there’s arguably no good that comes from it. Every year on the second Sunday in March, most places in […]
The possibilities were almost limitless, so why does everything line up? Our Solar System is an orderly place, with the four inner planets, the asteroid belt, and the gas giant worlds […]
In the quantum world of the unstable, even identical particles don’t have identical masses. In the microscopic world of the quantum particle, there are certain rules that are wholly unfamiliar […]
If the multiverse is real, why hasn’t our Universe, in a sea of infinite possibilities, run into another one at least once? The Universe we inhabit is vast, full of matter […]
Distances in the expanding Universe don’t work like you’d expect. Unless, that is, you learn to think like a cosmologist. There are a few fundamental facts about the Universe — its origin, […]
LISA, the Laser Interferometer Space Antenna, will not only be the space-based successor to LIGO, but will predict black hole mergers up to years in advance. Across the Universe, innumerable masses […]
