Could our universe have been born inside a collapsing star? That idea recently made headlines, and I got a lot of questions about it. The paper behind them describes a new solution to Einstein's equations in which a collapsing star expands on the inside and never forms a black hole. Let's take a look.

A group of astronomers say they've spotted more than twenty giant unidentified objects racing around the Moon, some of them forty kilometres across, and that the Moon serves as a base for them. The daily mail loved it. My bullshit meter did not survive it. But underneath all this nonsense there's a serious question that almost nobody is looking into. Let's take a look.

You've probably heard that quantum mechanics is spooky, that measuring one particle instantly affects another across any distance. A physicist now says there's a reason: the universe doesn't have one dimension of time, but two. It sounds absurd, but he's got the maths and even a way to test it. Genius or nonsense? Let's take a look.

The origin of life is one of the biggest mysteries left in science. Now a group of researchers says there wasn't just one origin, there were two. And I want to explain why, despite how impossibly long ago it all happened, I'm actually optimistic that we'll one day work out how life began. Let's take a look.

How special is Earth? It's one of those questions that runs through all of science, and here's a version of it most people have never thought about: why does our planet even have continents? A group of geologists now says the answer lies somewhere unexpected, in the shape of the Milky Way itself. Let's take a look.

The underground of New York is almost a city within a city. We kind of get used to having all these utilities and services that it’s easy to forget the physical space they all take up and the work that goes into installing and maintaining them.

What happened in New Orleans in August 2005 wasn’t a natural disaster. A number of engineering errors made the hurricane far more deadly than it would have been otherwise. And I built a model to show you why.
