Absolute hot facts for kids
Absolute hot is the highest possible temperature that anything in the universe can reach. Imagine the hottest fire you can think of – absolute hot is way, way beyond that! It's measured at about 1.416785 × 1032 kelvins. This is an incredibly huge number!
Absolute hot is the complete opposite of absolute zero. Absolute zero is the coldest possible temperature, where everything stops moving. Absolute hot is where everything is moving as fast and as much as it possibly can. When something reaches this extreme temperature, the normal rules of physics completely change.

What is Absolute Hot?
Absolute hot is also known as the Planck temperature. It's a theoretical temperature, meaning scientists believe it's the highest temperature possible, even if we can't create it easily. At this temperature, particles would be so energetic that our current understanding of physics, like quantum mechanics and general relativity, would need new rules to explain what's happening.
How Hot is Absolute Hot?
To give you an idea of how hot 1.416785 × 1032 kelvins is, let's compare it.
- The surface of the Sun is about 5,778 kelvins.
- The center of the Sun is about 15 million kelvins.
- Even a supernova explosion, which is one of the most powerful events in the universe, only reaches temperatures around 100 billion kelvins.
Absolute hot is many, many times hotter than all of these!
Why Can't Things Get Hotter?
Scientists believe there's a limit to how hot something can get because of the way energy and gravity work together. At absolute hot, the energy of particles would be so extreme that they would create tiny black holes. These black holes would then quickly evaporate, releasing even more energy. This cycle suggests a natural limit to temperature.
Absolute Hot and the Big Bang
Scientists think that temperatures close to absolute hot might have existed for a tiny fraction of a second right after the Big Bang. The Big Bang is the event that started our universe. In those first moments, the universe was incredibly hot and dense. As the universe expanded, it cooled down.
What Happens at Absolute Hot?
At absolute hot, the four fundamental forces of nature – gravity, electromagnetism, the strong nuclear force, and the weak nuclear force – might all become one single force. This is something scientists are still trying to understand with theories like string theory and quantum gravity. It's a very exciting area of physics!
