July 21, 2026 What If It Rained Oil?
Black Rain is falling on Tehran and it doesn't stop there. Oily, toxic, and flammable. Roads turn to ice rinks, planes fall from the sky, your tap runs brown, and crops die in the ground. One lightning strike could ignite the world.
Scientists already have a name for what comes after Black Rain. Drop it in the comments if you know.

July 21, 2026 What If You Explored Every Kepler Planet?
Some planets might look promising from a distance, but stepping onto them could turn them into the most dangerous places in the universe. In this episode, we explore the extreme worlds discovered by the Kepler Space Telescope and imagine what would happen if a human explorer tried to survive on them. From crushing gravity and toxic atmospheres to molten lava oceans and massive gas giants, these alien planets highlight the hostility of the universe.
What would it be like to land on Kepler-10b, a blazing lava world hotter than most metals can survive? Could anyone breathe on Kepler-62f, a planet with an atmosphere loaded with carbon dioxide? And what happens if you fall into the endless storms of the gas giant Kepler-16b? Even worlds that seem potentially habitable, like Kepler-22b or Kepler-452b, may hide deadly conditions that render survival nearly impossible.

July 20, 2026 What If You Dove Into the Sun?
You’re traveling through our Solar System when suddenly, you have the opportunity to reach out and touch our biggest and brightest celestial body.
Touching our Sun would require a heat-resistant spacesuit, the strongest sunscreen, sunglasses, and a lot of courage.
The risks of touching the Sun are high. You could be instantly obliterated if you touched the Sun. Could you take the heat?

You can fit over a million Earths inside our Sun, but Betelgeuse, a massive red supergiant, could engulf over a billion Suns. It's in its final fusion cycles, nearing a violent supernova.

If Betelgeuse replaced our Sun, it would consume half the Solar System before exploding. Survival prospects? Not promising. Explore this scenario and more.
