Cosmos:elementary | SPACE IS NOT COLD! From the Big Bang to Earth @Cosmos_elementary | Uploaded December 2023 | Updated October 2024, 30 minutes ago.
Many believe that space is cold. In movies, they sometimes show a person freezing instantly when exposed to open space without a spacesuit. But would that actually happen? In this video I will answer that question as well as talk about the coldest places in the universe, interstellar and intergalactic space, cosmic microwave background radiation, and absolute black bodies.
