Here's a concise summary of the seven things you didn't know:
1. **Pizza.com**: Chris Clark bought the domain "pizza.com" for $20 in 1994 without knowing what he'd do with it. He later sold it for $2.6 million after reading about someone who sold "vodka.com" for $3 million.
2. **A Body in Space**: If a corpse were placed in space, it would dry out quickly, neutralizing decomposition. Depending on its location, it might burn up, collide with satellites or debris, or last for thousands of years before being destroyed by radiation and micrometeorites.
3. **The Life of the Sun**: The sun will eventually die, but it's not massive enough to explode in a supernova. Instead, it will expand, cool, and dissipate, forming a white dwarf that will eventually become a black dwarf.
4. **A Murderer's Confession**: In 2012, a murderer voluntarily submitted a DNA sample 13 years after committing the crime, solving the case. This raises questions about the perpetrator's motivations and the power of remorse.
5. **Unsolved Mysteries**: A website called "Unsolved Mysteries" has helped solve around 70 cold cases and find hundreds of missing people through crowdsourcing and volunteer efforts.
6. **The Oldest Person**: Jeanne Calment holds the record for the longest human lifespan, living to 122 years. Her lifestyle, which included playing sports, eating chocolate, and not working, has been studied to understand the secrets of her longevity.
7. **The Oldest Being on Earth**: Endoliths, organisms that live in extreme conditions within rocks, have been found to have a reproduction cycle of around 10,000 years and can live for up to 250 million years, making them the oldest known living beings on Earth.
