What If: Science, Theory, and Possibilities

What would happen if you dove into the Mariana Trench? Explore the intense conditions of the deep ocean and discover rare footage from Earth's deepest point. Reaching the Mariana Trench is harder than landing on the Moon. Fewer people have visited Earth's deepest point than have walked on the lunar surface.

How deep does the ocean go? Explore the Mariana Trench, home to Earth’s deepest known point, and discover how its depths compare with Mount Everest. If Mount Everest were placed in the Mariana Trench, more than 2 km of water would still cover its peak. In a hypothetical ocean without water, a fall to the trench’s bottom would take roughly 3.5 minutes. The ocean covers about 71% of Earth’s surface, yet much of its seabed remains unexplored. Discover the extreme pressure, strange life, and vast depths beneath the waves.

War, environmental destruction, global warming, species extinction... Spaceship Earth is being trashed by its crew. It seems humanity needs a Plan B. Fast. And the obvious candidate? Mars is staring down at us every night. Mars has a total surface area almost equal to Earth's entire land area, offering plenty of room. With large sums of money directed to space exploration, it's not so far-fetched to ask: What if we moved all 8 billion humans to Mars? Ever wondered what would actually happen?

This isn't the first time you've pondered this question. Imagine the Universe not expanding but shrinking, with spacetime contracting until it forms a singularity smaller than a YouTube Like button. After collapsing, there's a possibility it could explode outward, similar to a supernova, creating a new universe. This could be the 'Big Bounce' instead of the Big Bang, potentially occurring countless times. Explore if the Universe starts shrinking and understand the implications on cosmic phenomena.

Our planet is hiding something remarkable from you. The ocean is vast, and if you dropped Mount Everest into the Mariana Trench, there'd still be over 2 km of water above its peak. Imagine if the ocean were devoid of water and you leapt down to the trench's bottom—it would take 3.5 minutes of free-falling to reach it. But water is abundant. Earth is 71% water, yet we know little about its seabed. It's a high-pressure, alien landscape, deeper than our tallest mountains. Today, we reveal just how deep the ocean goes.

What would happen if humanity decided to unleash nuclear weapons on every planet in our Solar System? From the scorching surface of Mercury to the icy edges of Neptune, this thought experiment pushes science, physics, and imagination to their limits. In this exploration, we examine how nuclear explosions would behave in diverse environments, such as the crushing atmosphere of Venus, the gas giants without solid surfaces, and the frozen worlds beyond. Would nukes even detonate the same way in space? Could they alter entire planets or barely leave a mark? 00:00: Nuking Every Planet in the Solar System00:58: Mercury03:14: Venus07:40: The Moon09:35: Earth12:24: Mars13:55: Jupiter17:52: Saturn19:01: Uranus19:44: Neptune20:46: Pluto Ever wondered what would actually happen?
