I’ll be back at the Ri on October 4th, talking about all things dark matter-y. Come along!
Dark Matter appears to have shaped the cosmos from its earliest moments. Yet despite its profound influence, Dark Matter has never been directly detected.

Well done Matt
It was so great to speak at Cheltenham Science Festival (in one of the biggest venues I’ve ever spoken in!). Hundreds of super keen students came to talk all things extraterrestrial life, as part of the Great Alien Hunt book tour 👽🧪🔭

Why Putin has to completely lose his war against Ukraine and his dictatorship in Russia.

If Europeans can unite around a common cause, Putin is more vulnerable than he seems. ✊🇪🇺

A call to Labour to Rejoin the EU.

"It’s nine years since the UK voted to quit the European Union. It has proven to be a disaster, and a disaster made greater by the election of Donald Trump.

The world is at a pivotal moment. Stark political reality faces us."
Labour needs to stop being so afraid about rejoining the EU
Rejoining would revive our economy and boost our security
