I always like you say that dark matter was one of the most begrudgingly agreed on theories in all of science.

If you want to get direct evidence, you need to make some dark matter in the lab, I think.

Dark energy. We know that it makes up roughly 70% of the universe. How do we know that?

Hello, and welcome to the supermassive podcast from the Royal Astronomical Society with astrophysicist, Dr. Becky Smith, and me, science journalist Izzy Clark.

Now, for those keen beans who listen to the very end of every episode, we appreciate you, by the way. You might have been expecting an episode on

the sun, but there's been a little bit of a change of plan. Yeah. So we have spent the last

all that stuff only makes up 5% of our universe. And quite frankly, that

makes my head spin. So earlier in July, the European Space Agency launched a space telescope

called Euclid, which is set off to give us important new insights into that remaining 95% of the

universe that's missing, namely dark matter and dark energy.

So that's given us a perfect opportunity to talk about all this stuff we've been just

ignoring the past three years. And so, you know, we just, we bumped the sun. Sorry, son.

Yeah, sorry. We'll get back to you at a later point. But before we get onto that big old search for the rest of our universe,

can I just say thank you to who?

Say thank you.

I'm so excited.

Can I just say thank you to everyone who has ever reviewed, rated or followed this podcast recently?

It really helps us keep that shiny number one spot as the best astronomy

podcast in the UK. And if you haven't done that yet, then please do, because all of that good stuff

really helps us keep making these episodes. Okay, that's my little rant done. Let's get on with it then.

So obviously, Dr. Robert Massey, the deputy
