Event Horizon Telescope and M87*

2:19So, our first story comes from the Event Horizon Telescope. Um, I'm sure you remember back in 2019 they imaged a black hole for the first time and there were so many memes, cat memes. Um, it was the first black hole that was ever photographed. I think the first image actually is the cat meme that I want to show everyone. It's it's the black hole and then as you zoom out it's it's it's the cat eyes. I thought that was pretty funny. It was all over social media because it's such a big deal, right? Um, for the longest time, black holes are things of theory. It's confined to the theory departments in physics,

But what I mean by that is they were really imaging the stars around the black hole, right? And they were they were looking at the star trails and you could see that there was some mass that was massive, millions of times the mass of the sun that was ringing these stars around in these capillarian orbits. And so there had to be a black hole in there. But to actually image a black hole, right, where you've got an event horizon, you've got the accretion disc around it, that is going to take an insane amount
