At SciTech Daily: New Theory Suggests That the Origin of Life on Earth-Like Planets Is Likely
According to a recent paper by a math professor at the University of Arkansas, the existence of life on Earth provides proof that abiogenesis is relatively easy on planets similar to Earth, refuting the “Carter argument” conclusion. Does the presence of life on Earth provide any insight into the likelihood that abiogenesis—the process by which life first emerges from inorganic substances—occurs elsewhere? That is a question that has baffled scientists for a while, as well as everyone else inclined to think about it. Astrophysicist Brandon Carter makes the widely accepted claim that the selection effect of our own existence limits our ability to observe. Nothing can be concluded about the likelihood of life existing elsewhere based on the fact that we had Read More ›
