Huge If True

This machine found something scientists thought was impossible… In the middle of the desert, miles from any city, are two HUGE concrete tubes. They’re part of a giant machine running the most precise experiment humans have ever built… Each tube is 4 kilometers long, and inside there’s a big metal pipe. And at the end of each pipe, scientists place some of the smoooooothest mirrors ever made. And then they fire a powerful laser that gets split down each tube, bouncing it back and forth… building up more and more power… until… they bring those beams back together… to discover something that just 100 years ago scientists thought was impossible to find! Finding it took hundreds of scientists and over a billion dollars. But what did we find?? And what’s the cutting edge we’re finding NOW that makes those scientists want to build… AN EVEN BIGGER ONE? Let me show you…

This is the craziest Olympic sport by far. Trust me. Every four years, people lose their minds over one Olympic sport. They make fun of it! But the more I learned about it, the more obsessed I got… and I realized that all these people making fun? They’re getting this totally wrong. This is the coolest Olympic sport by far. The sport I’m talking about is… CURLING. From stones so unique they all have to come from one tiny island, to a tech doping scandal nobody wants to talk about. It’s a game with strategy so complicated it’s called “chess on ice”. And a physics mystery that’s gone unsolved for over a century that could one day help us design robots for space. And that’s just the start… Trust me, you don’t know enough about Curling…YET. So I’m going to take you onto the ice at the Olympic Trials… to show you what everyone’s missing and why Curling is the Olympic sport you should be watching.

The deeper you go, the weirder it gets... Gigantic, monstrous, beautiful creatures thrive in the cold dark depths of our oceans. Until now though, most of our discoveries have just required decades of work for the chance to just get… lucky.

Something's hiding below the ice in Antarctica…. In 1970, a team of Soviet scientists started drilling. For 28 years, they kept going… until after nearly 4,000 meters… they suddenly stopped. Because they’d found something unimaginable: Liquid water. A secret lake, down below all this ice, that had been completely sealed off from the rest of the world for 15 million years. How? And… is there something alive in there? Creatures that have been evolving separately from the rest of the planet for 15 million years? Scientists started searching for more of these secret lakes, and as they did, they realized there is way more going on under Antarctica than we ever thought. I needed to know the truth about Earth’s most remote continent. So I've come all the way to Antarctica to show you what's really happening down below this ice. And exactly what they discovered when they finally broke inside…

Most people think of diamonds as expensive jewelry, or maybe as super-hard drills. But everyone’s missing the coolest story here… We’ve built giant machines that can recreate the conditions inside our planet. And found new ways to make diamonds way cheaper, now unlocking the hidden potential of this super material. People are sending diamonds into space, adding them to massive computers, and using them to help solve one of the biggest technological problems we’re about to face. This is about pushing the limits of material science to benefit all of us. So in this video, we’re getting rare access inside a lab where they make diamonds to see how they actually do it… And we’re gonna shrink down inside your computer to show you why diamonds are not what you think.

Off the coast of Sicily, there’s a massive underwater machine. It looks like a forest of floating spheres… And on the surface, hidden in an abandoned winery, a computer watches them and waits. And in 2023, they saw something… Something WAY smaller than an electron tore through that forest, setting off a signal nearly 30x more powerful than anything like it we’ve seen before, which means something HUGE must have happened way out in space. This crazy experiment is not alone! Down in Antarctica, buried deep in the ice, are over 5000 more of these mysterious spheres. Together, these two machines – called KM3net and Ice Cube – are part of a massive global effort to give us a brand new way to find and look inside the biggest, most extreme, cosmic events in our universe. But to do it, they need to catch the most elusive particle in all of physics.

This is ANTARCTICA. And in 1985, it became the center of a global crisis… Directly over Antarctica, high up in the stratosphere was a massive hole. And if we hadn’t done anything about it, today, we’d be living in an alternate world. By now, a hole would be forming over the North Pole as well. By 2040, the “hole” would be over the entire planet. By 2065, skin cancer rates would be soaring. Kids wouldn’t play outside much anymore… But that’s NOT the world we’re living in! In fact, you’ve probably stopped hearing this story altogether. That wasn’t by accident. It was a choice. Two choices, both of which dramatically changed the course of human history for the better. So let me show you how that happened and what's about to happen next. Because it turns out, the little sliver at the bottom of the map is actually the center of everything/our whole planet. And you need to see this now, because scientists say we need to make the next big choice.
