All scientific theories, at some level, are wrong. That’s why consensus is so vital. There are two important and common words that, when used scientifically, have a very different meaning than […]
The theoretical reasons to expect it are compelling, but the technology required to detect it is unfathomable. All throughout our galaxy, millions of black holes of a variety of masses […]
There are exposed planetary cores orbiting stars, and we may have already found them. When we take a look at the planets in our Solar System, there’s a pretty clear difference […]
Our Universe is 13.8 billion years old, and our Sun formed about 2/3rds of the way through. Here’s what came before it. When it comes to the great cosmic question 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 […]
There’s no such thing as a theory that’s too beautiful to be wrong, if it doesn’t agree with experiment. The history of physics is filled with great ideas that you’ve […]
We always assume that dark matter is particle-based, and we just need to find which particle it is. But what if it isn’t so? Everything we’ve ever detected in the Universe, […]
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 […]
All of this has happened before… but not like this! As the year draws to a close, we approach a very special time of year, at least from an astronomical perspective. […]
If nature makes equal amounts of matter and antimatter, how are we here? When you look out at the vastness of the Universe, at the planets, stars, galaxies, and all there […]
Oregon, Idaho, and Wyoming are all on fire, and simply driving your car can be the most dangerous thing of all. “I’d rather fight 100 structure fires than a wildfire. With […]
This isn’t an XZibit joke; it’s a real scientific question. And the answer may be that it’s possible after all. “People who work every day are kind of scared of things […]
If you thought our galaxy was just the luminous matter within it, think again. “Things need not have happened to be true. Tales and adventures are the shadow truths that […]
Gravitational waves and electromagnetic ones don’t need to go together. But physics says it’s possible; what do the observations say? “The black holes collide in complete darkness. None of the […]
Where liquids are impossible, science gets really interesting! “You can’t cross the sea merely by standing and staring at the water.” –Rabindranath Tagore If you brought liquid water into outer space, […]
But that doesn’t mean it actually works as advertised. “All of the books in the world contain no more information than is broadcast as video in a single large American […]
There are strict scientific standards a new ‘claimed discovery’ needs to meet. Has cold fusion gotten there? “Between cold fusion and respectable science there is virtually no communication at all. …because the […]
It’s the ‘nightmare scenario’ for some. But for Sabine Hossenfelder, it might be a dream come true. This article was authored by Sabine Hossenfelder. Sabine is a theoretical physicist specialized in […]
Einstein’s most famous equation didn’t have to be this way, but it is, all the same. “Science is global. Einstein’s equation, E=mc^2, has to reach everywhere. Science is a beautiful gift […]
13.8 billion years is a great number. But how sure are we of this, and how did we get there? “Nobody grows old merely by living a number of years. We […]
More than a million times what we make at the LHC, these could be the ultimate keys to nature. “Energy is liberated matter, matter is energy waiting to happen.” –Bill Bryson […]
A live blog event from Nobel Prizewinner Art McDonald. “It’s ironic: in order to observe the Sun, you need to go kilometers underground.” –Art McDonald In the 1960s, a huge […]
They’re judged to be “standard candles” and the greatest cosmic distance indicators. What if they’re not so standard? “It’s everywhere, really. It’s between the galaxies. It is in this room. […]
If they shoot out straight lines of high-energy particles, why do they carve bubble-like shapes? “When a person starts to talk about their dreams, it’s as if something bubbles up […]
It’s a wonderful potential technology for going interstellar. But in your lifetime? Don’t hold your breath. “Greatness is not in where we stand, but in what direction we are moving. We […]
A live-blog event of a fabulous public lecture given by Katie Freese on the unseen components in our Universe. “If you take everything we know… it only adds up to […]
If there is a quantum theory of gravity, is String Theory the only game in town? “I just think too many nice things have happened in string theory for it to […]
An incredible live-blog of an incredible event. “It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new […]
Throwback Thursday: How Dark Matter’s #1 Competitor Died The only way out is to modify the laws of gravity, and our best observations rule those modifications out. “The discrepancy between […]
