Study Notes
Panspermia Overview
- Panspermia is the hypothesis that life exists throughout the universe and is distributed by meteoroids, asteroids, comets, and space dust.
- It suggests that microorganisms or their precursors can survive the harsh conditions of space travel and subsequently initiate life on other planets.
Criticism of Panspermia Theory
- A major criticism is the lack of evidence supporting the survival of organisms in space and the means of eventual colonization of other planets.
Focus of Panspermia Studies
- Research in panspermia primarily investigates the viability of microorganisms in extreme space conditions, including radiation and vacuum.
- Studies aim to understand how life could spread from one celestial body to another and the implications for the origins of life on Earth.
Pseudo-Panspermia
- Pseudo-panspermia, also known as "directed panspermia," refers to the idea that advanced extraterrestrial civilizations intentionally spread life to other planets.
Lifeforms Proposed by Panspermia
- Panspermia proposes that resilient microorganisms, such as bacteria and spores, are capable of enduring the harsh conditions of space, including radiation and extreme temperatures.
