Science & Tech
Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever. The ultimate goal of physics is to accurately describe, as precisely […]
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 […]
It’s not just for Earth-like planets around Sun-like stars. Not even close. Shortly after Earth first formed first formed, life quickly took hold, thriving ever since. Both reflected sunlight on a […]
It isn’t just that mass and energy are equivalent and interchangeable. It tells us something fundamental about mass itself. Of all the equations that we use to describe the Universe, perhaps […]
A year ago, a puzzling gap existed between black holes and neutron stars. With nearly a year of new data, LIGO solves the puzzle. On Monday, March 16, 2020, astrophysicist Carl […]
And why social distancing, isolation, and sheltering-in-place are so effective, but only if we do them early enough. In any biological system, if you put a living organism into an environment […]
And if you have a friend at the same longitude, you can even measure its circumference. This year’s equinox, on March 19/20 of 2020 (longitude-dependent), is Earth’s earliest in 124 […]
You’d have to throw out a lot of known physics for this to even be a possibility. Here’s why. It’s an undeniable scientific fact that dark matter must exist in order […]
It’s an incredibly useful approximation. But the truth takes us far deeper. Anyone who’s ever taken a physics course has learned the same myth for centuries now: that any object thrown, […]
The full Moon is always a sight worth looking at. This March, the full Worm Moon is a little more “super” than usual. The full Moon is always a spectacular sight: […]
Unbelievably enough, it all comes back to Pythagoras. One of the first theorems anyone learns in mathematics is the Pythagorean Theorem: if you have a right triangle, then the square […]
After the Big Bang, merging supermassive black holes are unparalleled. Here’s how we’ll find the first one. Last week, NASA’s Chandra X-ray observatory made history by announcing the most energetic explosive […]
A black hole punched a hole 15 Milky Ways across in a galaxy cluster’s gas, by far the largest ‘kaboom’ ever seen. The Universe, everywhere we look, is full of cataclysmic […]
It’s not a lack of motivation, intelligence, or capability. Here’s how to open a space. Over the past 20 years, the number of bachelor’s degrees awarded in physics has more than […]
Ever wonder, exactly, how stars form from molecular gas and dust? So do scientists. One of the great challenges for astronomy is to determine, in gory detail, how stars are […]
Scientific surprises are often how science advances. But more often than not, they’re just bad science. When you’re a scientist, getting an unexpected result can be a double-edged sword. The best […]
And how cutting just $1 billion per year in funding from NASA’s budget would be a catastrophe for science. When you think of the great cosmic beyond and what we know […]
Only one dark matter detection experiment ever gave a positive result, in conflict with all the others. This could be why. For multiple generations now, it’s been apparent to astronomers that […]
We’ve come fantastically far in our understanding of the distant Universe. Here’s how we’ll go even farther. Sometime in 2021, NASA’s James Webb Space Telescope will launch, deploy, and begin science […]
It’s been called the biggest conundrum in all of cosmology, and recent measurements just add to the confusion. One of the most puzzling facts about the Universe is that different […]
