According to Phys.org, a paper published in the Journal of Cosmology and Astroparticle Physics theorises that life on Earth may be premature. Reportedly, there is a greater chance of life developing on any planet in the distant future than right now, particularly if the planet is circling a long-living red dwarf that is, unless they prove to be too deadly to near-by planets. The paper can be read online.
Life as we know it first became possible about 30 million years after the Big Bang, when the first stars seeded the cosmos with the necessary elements like carbon and oxygen. Life will end 10 trillion years from now when the last stars fade away and die. Loeb and his colleagues considered the relative likelihood of life between those two boundaries.
The dominant factor proved to be the lifetimes of stars. The higher a star's mass, the shorter its lifetime. Stars larger than about three times the sun's mass will expire before life has a chance to evolve.
Conversely, the smallest stars weigh less than 10 percent as much as the Sun. They will glow for 10 trillion years, giving life ample time to emerge on any planets they host. As a result, the probability of life grows over time. In fact, chances of life are 1000 times higher in the distant future than now.
