- Researchers say lifetime of a star is crucial to formation of planet and life
- High mass stars will die long before life can evolve on nearby planet
- Those with low mass can survive for 10 trillion yrs, allowing enough time
- But, they say low mass stars may create too hazardous an environment
Scientists have long searched for proof of alien life, yet it remains unknown if other beings have ever existed outside of our planet, or if life on Earth is truly alone in the universe.
Now, researchers say Earthlings may just have arrived early.
On a cosmic timeline, a new study argues that life on Earth may be premature, and say other potentially habitable worlds could one day produce life given enough time – roughly 10 trillion years.
