The future is dark, and I don’t mean the upcoming US elections, I mean that stars in the universe will eventually all burn out. They’ll clump together and form black holes. The black holes will evaporate, leaving behind nothing but a very thinly distributed, cold, and dark gas. And that’s how it will remain, forever. Game over.
Well, maybe n...

It’s hard to keep track of all the things that will supposedly fix climate change but won’t. Such as hydrogen, veganism, or quantum computing. Wait what? Yes, marketing quantum computers as miracle cure for climate change has not fallen out of fashion despite my many jokes about it.

We’ve heard that space debris is bad and the problem’s getting worse, but here’s a new thing to worry about. It could interfere with the earth’s magnetic field, which is our major protection from the highly energetic particles of the solar wind.
Space debris, aka space junk or orbital debris, comes from stuff like ...

There are a lot of bad arguments against nuclear power. For example, that it’d just be too simple a solution to climate change, we need to make the transition difficult and painful. That’s not a good argument because it’s not actually that simple to prevent further global warming, even with nuclear power. But there are two go...

This video is all about Albert Einstein, yes, that guy again. Einstein is famous for his theory of general relativity. It’s taught us that gravity is not a force. And that’s probably the most misunderstood physics fact, ever. Like, even physicists get it wrong, all the time. Gravity is not a force. And since there’s no force pushing down on you, that means y...

Scientists have long speculated that life didn’t begin on earth but in space. According to a new preprint, life could have come from intergalactic gas clouds, so let’s have a look.

I though, I have a talent for pissing off climate scientists, but I have to bow to Sultan Al Jaber who had climate scientists fuming for saying that there’s no science behind a fossil fuel phase out. He is, of course, entirely correct, which raises the interesting question whether fuming climate scientists emit carbon dioxi...

The Brick is a boxy cloud of opaque dust at the centre of the Milky Way, which has confused scientists ever since its discovery 30 years ago. It just got even weirder.
Astrophysicists originally thought that the Brick was just full of dense gases, which would absorb light. But then it should also have been full of young stars...

Complexity. It sounds very sciency, doesn’t it. Everyone loves to talk about complex problems and complex systems, but no one has any idea what it means.

This is the maybe most surprising development in theoretical physics I’ve seen for a decade or so. A well-renown physicist is saying that there’s a mistake in a proof that dates back half a century, and black holes might not actually contain singularities.
