The Fermi Paradox
Enrico Fermi questioned why we haven't encountered extraterrestrial life given the vast number of stars. Possible explanations include the rarity of life-supporting conditions or the propensity for intelligent life to self-destruct.
Drake Equation Estimations
The Drake Equation estimates the number of active, communicative extraterrestrial civilizations in the Milky Way. It incorporates factors like star formation rates and the likelihood of life-supporting planets.
UFO Sightings and Research
Unidentified Flying Objects (UFOs) have been reported for centuries. Governments and private organizations have investigated these phenomena, often attributing them to natural or man-made causes.
Astrobiology's Growing Field
Astrobiology studies the potential for life elsewhere in the universe. It examines extremophiles on Earth that survive in harsh conditions, suggesting life's possible resilience on other planets.
Exoplanet Habitability Studies
Thousands of exoplanets have been discovered. Scientists assess their habitability based on factors like distance from their stars, composition, and atmosphere, seeking Earth-like conditions.
SETI's Listening Efforts
The Search for Extraterrestrial Intelligence (SETI) uses powerful telescopes to scan for signals from advanced civilizations. Despite extensive searching, no definitive extraterrestrial signals have been confirmed.
Breakthrough Initiatives
Breakthrough Initiatives, funded by Yuri Milner, include Breakthrough Listen, to detect alien signals, and Breakthrough Starshot, aiming to send probes to nearby star systems.
