About 5% of the reported unidentified anomalous phenomena — or so-called UFOs — can’t be explained and should be thoroughly investigated by mainstream scientists according to Etienne Caron (Canada). Together with Massimo Teodorani, astrophysicist at the Italian National Institute for Astrophysics (INAF), he tells us why, how and where mainstream scientists can play an active role in understanding the anomaly. In essence, they are not saying that UFOs are carrying intelligent beings from outer space, but do recognise the importance of monitoring the events in a more rigorous and deterministic way.
