Well that's interesting.
The reason we havent heard from any other intelligent life in the universe remains a perplexing problem, known as the Fermi Paradox, considering how abundant planets are thought to be. What if, though, Earth was simply incredibly early onto the scene? What if we are among the first sentient life in the universe?
Thats a theory proposed by new research, using data from the Hubble and Kepler space telescopes, which suggests that 92% of potentially habitable planets in the universe are yet to be born. Based on the slowing rate of star formation, but the huge amounts of interstellar dust and gas remaining, researchers at the Space Telescope Science Institute (STScI) in Maryland suggest that the vast majority of Earth-like worlds that will ever exist simply havent formed yet.
Compared to all the planets that will ever form in the universe, the Earth is actually quite early, study co-author Peter Behroozi of STScI said in a statement.
Well that's interesting.
