The hottest known temperature in the universe is the Planck temperature, which is:
🔥 Planck Temperature:
~1.416808(33) × 10³² Kelvin (K)
🌌 What Is It?
- It’s the theoretical maximum temperature where known physics breaks down, especially gravity and quantum mechanics.
- Above this temperature, current physical theories, including general relativity and quantum field theory, no longer apply.
- Thought to occur immediately after the Big Bang, during the Planck epoch (10⁻⁴³ seconds after time began).
💥 Hottest Real Events Observed
Here are some actual high-temperature phenomena observed or created:
| Event | Temperature | Description |
|---|---|---|
| Big Bang (earliest moments) | ~10³² K | Universe's beginning, likely reached Planck temperature. |
| Large Hadron Collider (CERN) | ~5.5 trillion K | Created in heavy ion collisions (quark-gluon plasma). |
| Supernovae cores | ~1 billion K | Core-collapse explosions of massive stars. |
| Neutron star mergers | ~100 billion K | Extreme collisions observed via gravitational waves. |
