Why deep sea maps are SO BAD (and how to fix it)... Subscribe for more optimistic science and tech stories. Our maps of the ocean are surprisingly bad! On Google Maps it looks like we know so much… but we know less about the ocean floor than we do the surface of Mars. And that’s a big problem, because we are using the ocean all the time: We’re laying internet cables across it, we fight wars in it, we search it during a crisis - like the imploded OceanGate Titan submersible or the missing Malaysia Airlines Flight 370. 71% of the surface of the Earth is water! And yet we have a surprisingly limited view of what’s below it.

Honestly, with all the jargon and hype (VR! AR! Spatial computing! Metaverse!), I’ve been tuning out the news about these devices for a while. But now, I think it’s time to turn the volume back up and pay attention. There is a deeply optimistic future that’s possible here. Not Ready Player One, but something else entirely. I’m going to try to show you what it might really look and feel like. If the Apple Macintosh helped unlock personal computing, and the iPhone unlocked computers in our pockets, what is this device supposed to unlock? My optimistic take is that this kind of tech is the most direct path to a totally sci-fi ability I never thought I’d see in real life. Something physically impossible in the real world… but maybe not in a digital one…

Right now, we’re living through one of the most pivotal moments in food history… and most people have no idea it’s happening.

You’ve heard about quantum computers. Maybe you’ve seen the “race for quantum supremacy” between governments and companies, or read that quantum computers will break all encryption, or heard terms like “qubits” or “superposition” or “quantum mechanics” in a confusing tv segment. But you might be wondering… what does a quantum computer actually DO? And how could it actually affect my life?

Imagine, it’s 2034, and a rock the size of a mountain, far off in our solar system is on a direct impact course for Earth. How would we know? And what would we actually DO about it? In this video, we play out a fictional asteroid headed for Earth – with help from my friend and former NASA engineer Mark Rober and rare access into a remote facility where they discover NEW asteroids – to show you all the real science and tech we would use to defend our planet if an asteroid is about to hit Earth!

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.

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.

The first all electric Ferrari, the Ferrari Luce, isn't what you think... (feat. Apple legend Jony Ive and Ferrari Chief Designer Flavio Manzoni) For more optimistic science and tech stories, subscribe to HUGE*! You’re about to see the first ever all electric Ferrari. A car Ferrari said they’d never make, that will probably be the most controversial car they’ve ever made. Above all, it will definitely be a massive risk – new tech and new design that will impact all of us, whether or not we ever drive a Ferrari. I’m at a secret track in Italy to get a first look before it launches. And talk to the two people most responsible for it: Apple legend Jony Ive who showed me the crazy details inside this car. And Ferrari Chief Designer Flavio Manzoni who told me the real reason they made it, and why it matters – for Ferrari, electric cars, and you and me.

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.

Have you ever thought, “what if I just dug a really really deep hole?” Well, the USSR actually did. The hole they dug is deeper than the deepest part of the ocean. It’s deeper than Mt. Everest is tall! They began digging it in the 1970s as part of a space race, but down. The United States only got to 600 ft before pulling funding. But the USSR kept going for 20 years. They made it about a third of the way through the Earth’s crust and then STOPPED.
