In recent years, there has been an upsurge in reports by the military on sightings of UFOs including detecting the same object with multiple modalities at once (examples: 1, 2).
Avi Loeb proposes to create a network of high-resolution sensors, (just as the military have). But compared to the military their results will not be classified and can be openly analyzed by scientists. The cost of doing this is in the order of millions of dollars.
Knowing if there are aliens has many consequences, including for the longtermism, since if the universe is densely populated, its expected moral value does not depend solely on our decisions.
