| Future Earths |
Based on Peeples and Behroozi's calculations, only about 8 percent of the planets of this type that the universe has the potential to create had been created when our own planet was born. That leaves a whopping 92 percent that are trailing behind us.Considering the fact that it took hundreds of millions of years for the very simplest forms of life on Earth to show up, and another few billion years for us and our animal friends to evolve intelligence, there's a good chance that the brunt of potentially habitable worlds won't have their day until ours is long over.Then again, there are already an estimated 1 billion rocky, Earth-sized planets in our galaxy alone, many of which may be in the habitable zones of their host stars. So even if the odds are bound to be better in a few trillion years, they're not so horrible today.
So there’s plenty of hope for Earthlings of the future to travel through space to new worlds (if we don’t kill our own earth first through GHG).
