Every EXTREME Temperature In The Universe Explained in 12 Minutes

In this video, I take you through the most extreme temperatures in the universe — from lightning heating the air to around 30,000°C, to matter being cooled so close to absolute zero that atoms begin behaving like one giant quantum object. We’ll travel inside the Sun’s 15-million-degree core, watch a massive star collapse into a supernova reaching around 100 billion degrees, and see what happens when two neutron stars smash together at a significant fraction of the speed of light. Then things get even stranger. At trillions of degrees, protons and neutrons begin to lose their normal identity, creating quark–gluon plasma. We’ll go back to the early universe, when temperatures this extreme filled all of space, before reaching conditions where even the fundamental forces of nature stop behaving the way they do today. Finally, we reach the Planck temperature — around 1.4 × 10³² kelvin — where quantum mechanics and gravity collide, spacetime itself may behave differently, and our current understanding of physics can no longer reliably tell us what happens next.

Some temperatures and conditions discussed cannot be measured directly and are instead inferred from observations, experiments, simulations or theoretical physics. Certain ideas about the most extreme temperatures — particularly at the Planck scale — remain unconfirmed. Some scientific details have been simplified to keep them easy to understand. The goal is to spark your curiosity, not replace proper research. Bluntly Explained explores the most extreme objects, events and mysteries in the universe — explained simply, visually and without the fluff.
