Could We Actually Detect Life on Other Planets?

The video explores the possibility of extraterrestrial life, discussing the odds of life evolving elsewhere and the challenges in detecting it due to vast distances. It covers methods to search for intelligent life, such as looking for megascale engineering like Dyson spheres. The video also delves into detecting simple life forms through biosignatures like biofluorescence and chemical disequilibrium in atmospheres. However, it highlights the ambiguity in confirming life due to abiotic processes, using the example of Tabby Star, where dust was mistaken for alien activity.

Explain the concept of chemical disequilibrium and its relevance to detecting life.

What recent observations raised questions about the existence of a Dyson sphere?

Why is it important to continue refining methods in the search for extraterrestrial life?
