SAS Lecture: Are we Alone...
About this event :

Whether humanity is alone in the universe is currently unknown, though many scientists consider it statistically unlikely given the trillions of galaxies, stars, and planets in the cosmos.
While no definitive evidence of extra-terrestrial life has been discovered, ongoing searches are focused on finding habitable exoplanets, atmospheric biosignatures, and potential techno signatures.
Key Perspectives and Scientific Context:
- Vast Potential for Life: With over 100 billion stars in the Milky Way, many hosting planets, the sheer number of possible environments for life makes total isolation improbable.
- The Fermi Paradox: This paradox highlights the contradiction between the high probability of extra-terrestrial life and the complete lack of evidence (or contact).
- Ongoing Exploration: Projects, such as SETI, or the UCLA SETI team, utilize advanced telescopes to scan for radio signals. Astronomers are also using the James Webb Space Telescope to study the atmospheres of exoplanets for signs of life.
- Unknown Odds: Despite the high probability, the precise conditions required for life to arise remain unknown, and Earth could be a unique anomaly.
The search continues, and finding life—even microbial—would fundamentally change our understanding of the universe.
