Summary:
- According to a supercomputer simulation, life on Earth will likely end in 1 billion years due to the gradual increase in the Sun's brightness.
- As the Sun ages, it will become hotter and brighter, causing the Earth's surface temperature to rise to the point where it becomes uninhabitable for most life forms.
- The simulation suggests that complex life on Earth will likely go extinct in around 1 billion years, although some simple lifeforms may be able to survive for a few hundred million years longer before the planet becomes completely inhospitable.
