- Life Origins? What Is Life? What Is To Be Alive?
A series of Conversations / Podcasts between Carl Zimmer and eight leading thinkers on the question of what it means to be alive.
What Is Life? was recorded at Caveat in New York and is supported by a grant from Science Sandbox, a Simons Foundation initiative.
'Panspermia'...
Panspermia (from Ancient Greek πᾶν (pan), meaning 'all', and σπέρμα (sperma), meaning 'seed') is the hypothesis that life exists throughout the Universe, distributed by space dust, meteoroids, asteroids, comets, planetoids, and also by spacecraft carrying unintended contamination by microorganisms. Distribution may have occurred spanning galaxies, and so may not be restricted to the limited scale of solar systems.
Panspermia hypotheses propose (for example) that microscopic life-forms that can survive the effects of space (such as extremophiles) can become trapped in debris ejected into space after collisions between planets and small Solar System bodies that harbor life. Some organisms may travel dormant for an extended amount of time before colliding randomly with other planets or intermingling with protoplanetary disks. Under certain ideal impact circumstances (into a body of water, for example), and ideal conditions on a new planet's surfaces, it is possible that the surviving organisms could become active and begin to colonize their new environment. At least one report finds that endospores from a type of Bacillus bacteria found in Morocco can survive being heated to 420 °C (788 °F), making the argument for panspermia even stronger. Panspermia studies concentrate not on how life began, but on methods that may distribute it in the Universe...
