The old idea of running with springs on your feet gets a high-tech makeover.
A fascinating mathematical structure exists that goes well beyond our common experience. Could it revolutionize physics? Perhaps the most remarkable fact about the Universe is that every particle within it — at […]
And how it might ensure that future generations won’t have to face anything like this ever again. As of April 6, 2020, more than 1.3 million people worldwide have tested positive […]
The university model needs to evolve.
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 […]
The inevitable long, slow decline is accelerating, and there’s nothing we can do. The Universe, as it is today, is less active, is forming fewer stars, and is creating fewer chances […]
Somehow, the Universe began with just the right mix of cosmic ingredients to make life possible. It sure doesn’t seem likely. When you take stock of what’s in the Universe on […]
The strongest tests of curved space are only possible around the lowest-mass black holes of all. One of the most mind-bending concepts about the Universe itself is that gravity isn’t due […]
As time goes on, every galaxy beyond our local group will speed away from us faster and faster. And yet, more will keep appearing. The farther away a galaxy is […]
Small sample size? No underlying theory? Conflicts with all other results? It checks all the boxes. There’s nothing that’s special, on a cosmic scale, about our place in the Universe. Not […]
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 […]
Is information the fifth form of matter?
Light cannot escape from a black hole, no matter what. But when two black holes merge? They just might. On September 14, 2015, history was made as the NSF’s twin LIGO […]
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 […]
It’s true that we have a thermodynamic arrow of time, and entropy always increases. But that can’t explain what we perceive. One of the enormous conceptual ideas that came along […]
The Planck length is a lot smaller than anything we’ve ever accessed. But is it a true limit? If you wanted to understand how our Universe operates, you’d have to examine […]
It doesn’t propagate at infinite speeds, and that’s a problem for Newton. When you look at the Sun, the light you’re seeing isn’t the light that’s being emitted right now. Instead, […]
Sure, cosmic inflation has its detractors. But it also has something no alternative possesses: predictions and tests. Perhaps the most compelling part of any remarkable story is its origin: how it […]
It isn’t just a day that comes every four years; it’s everything we need to keep our calendar aligned with Earth’s orbit. Once every four years, at least under most circumstances, […]
It’s one of our five major personality traits, and arguably, it’s the worst one. Why are some human beings neurotic?
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 […]
In physics, anything that isn’t forbidden must occur. So why don’t the strong interactions violate CP-symmetry? If you ask a physicist what the biggest unsolved problem facing the field today […]
In General Relativity, the fabric of space doesn’t remain static over time. Everything else depends on the details we measure. If there’s one thing we’ve experimentally determined to be a constant […]
When you hear ‘quantum,’ you probably think of splitting everything into discrete, indivisible chunks. That’s not necessarily right. If you want to learn what the Universe is made out of […]
Thankfully, there are ways to combat mental and physical fatigue, even in isolation.
And, even with all we know, what still remains unexplained? At a fundamental level, our Universe is made of particles, forces, interactions, and the fabric of space and time. Spacetime […]
Focusing on the present moment has some strange effects on how people estimate stretches of time.
A new paper claims that scientists might be wildly mistaken about the density — and therefore, the shape — of our universe.
As more data comes in, the puzzle gets deeper and deeper. Whenever you set out to solve a problem, there are a series of steps you have to take in order […]
