Sobre o podcast
An epic exploration of possibilities. What If is a Webby Award-winning science web series that takes you on a journey through hypothetical worlds and possibilities, some in distant corners of the universe, others right here on Earth. Each scenario examines a scientific theory, research or fact through a hypothetical question.

What would happen if every glacier on Earth melted instantly? Explore a hypothetical world of rising seas, flooded cities, disrupted rivers, and cascading climate disasters.
Compare three scenarios: the sudden loss of alpine glaciers, the melting of Greenland and Antarctica's vast ice sheets, and the disappearance of floating sea ice. Discover how ice loss could reshape coastlines, alter gravity's influence on ocean levels, and accelerate global warming through the albedo effect.
From a potential 65-meter (215-foot) sea level rise to the physics of hypothetical tsunamis, this episode examines which places might survive, what civilization could face, and whether glaciers could ever return.

What if Earth's continents had never split apart? Imagine a modern-day Pangea: one massive supercontinent where the air is hot, thick, and heavy with the scent of wet mud and pine. Your lawn is a dense fern jungle, and a massive, toothy relative of the crocodile waits where your driveway should be.
Explore what this alternate Earth might look like, which creatures could rule it, and whether humans would ever have evolved.

What if Earth's oceans boiled away in an instant? Explore how vaporizing the oceans could transform our planet—and ask how long it would take for the sky to catch fire.
In about 5 billion years, the Sun will exhaust the hydrogen in its core and expand into a red giant. As it grows, the intense heat could vaporize Earth's oceans. But what would happen if that distant scenario unfolded right now?

What would happen if Earth's oceans instantly boiled away? Explore a world of crushing atmospheric pressure, runaway greenhouse heating, supercritical water, and a potentially molten crust.
Our Sun will eventually exhaust the hydrogen in its core and expand into a red giant, dramatically heating Earth. But what if the oceans vaporized today? Could the sky really catch fire, and how would the planet's atmosphere change?
This episode explores hydrogen physics, Earth's thermal equilibrium, atmospheric loss, deuterium, and what a Kardashev Type 1 civilization might do with planetary-scale energy.

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?

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.
