 When we say our observable universe or just our universe for short, we don't mean all of space, we mean this, the region of space from which light has a time to reach us during the 13.8 billion light years since our big bang. Meaning there is plenty more outside of this that we have yet to have the light come to us. Yeah, probably. We haven't seen it yet. But every time we wait one more minute, light reaches us from another light minute away when more stuff comes into view. We've never suddenly had come into view a sign saying space ends here. So our observable universe is constantly opening up. Yeah, it is. So what we need first of all is hefty dose of humility because we humans have again and again made this mistake of thinking that everything we knew about was everything that existed. Just to discover that that was just a small part of a much grander structure, a planet, a solar system, a galaxy, our universe. That we were the center and then we weren't the center. We weren't just the star. We have a long track record of hubris. Hubris, yeah. So humility is all good. Yes. Now, how much is there actually? Well, pretty much all of my physics colleagues think that space is a lot bigger than this. And again, every minute we wait, we see in fact more. The most popular theory we have for what made our space in the first place, made it so big, called inflation actually predicts in the simplest versions of space goes on forever. And if that's true, then you can fit infinitely many other universe-sized regions into this where there will also then be galaxies. And ultimately, if you roll the dice and things start at randomly copies of us having all sorts of variants of this combination, this is what I call the level one multiverse. And if it sounds weird, it's only the simplest four levels. And I want to make sure this is explained. So Max is saying we are at the very center of this sphere. Not because there's anything magical about this edge. It's just that if you're walking in the fog and the visibility is 100 meters, you'll feel that you're in the center of your own little fog sphere. Yes. And that the extension of the universe goes in all the directions in infinite amount from here. And that the reason why there is this red ring around the center is because this is where are the disc of our galaxy. Yeah, this is just a photo of the edges of the part of space that we can see taken with microwave cameras on this NASA satellite WMAP that's taking baby pictures by looking at the light that's been traveling for 30.8 billion years to us, seeing that when a universe was 400,000 years old, it was super hot. And it only cost us each 20 pens, as you said. 40 cents per American to make these tremendous discoveries. So next time you think about the money that's being allocated towards science, give those big thumbs up. Yeah, I've never met anyone who would forfeit one bite of a burger for these deep secrets about the cosmos.
