What If: Science, Theory, and Possibilities

Explore the true scale of the cosmos as we journey from our home star to some of the largest known objects in the universe. While our sun dominates our solar system, accounting for 99.86% of its total mass, it is surprisingly small compared to other stellar giants. In this episode, we compare the sun to several massive stars. Ever wondered what would actually happen? Dive into our biggest What If scenarios and go deeper with the What If community.

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?

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. Ever wondered what would actually happen?
