How to Approach the Problem of ‘Oumuamua

Abraham Loeb: Galileo Galilei taught us through experimentation that despite our gut feeling, heavy objects do not fall faster than light objects. Similarly, experiments have taught us that “spooky action at a distance” is a feature of quantum mechanics, despite Albert Einstein’s gut feeling that such a thing was impossible. The lesson from these historic examples is that in questions of science, we should base our inferences on evidence and not prejudice. Before the truth becomes evident, there is a long period of uncertainty with some “gut feelings” being misguided. How can we gather more data on the population of ‘Oumuamua-like objects, so as to shorten the period of uncertainty about their origin? The simplest approach would be to seek new interstellar objects in surveying the sky.
