The New Case for Panspermia

The idea that the seeds of life are ubiquitous throughout the cosmos goes back to Anaxagoras, a Greek philosopher. In the 1800s, French chemist Louis Pasteur proposed that spontaneous generation of life could not have occurred on Earth. British physicist Lord Kelvin and others jumped on Pasteur’s bandwagon and suggested that life might have come from space. But modern-day panspermia advocates have been the Rodney Dangerfields of science. In fact, just two leading researchers carry the bulk of the panspermia torch. The renowned Sir Fred Hoyle, known for his studies of star structure and the origin of the chemical elements in stars, has worked with Chandra Wickramasinghe over the past three decades to pioneer the modern theory of panspermia.
