I know this is a long shot but is it possible to detect life on other planets by the metal and trash sphere all modern societies must eventually accumulate around their planet? We have just begun, I can only imagine how crazy it is going to get around our own planet.
- rybosome 10y agoPerhaps, but we are still dealing with the challenge that the light of a star completely dominates the light from planets nearby. Telescopes like the James Webb Space Telescope schedule for launch in 2018 should be able to filter out the starlight and theoretically perform spectroscopy on the planetary light, which could reveal biomarkers like oxygen in the atmosphere.
