Why is Harvard astrophysicist Avi Loeb working with ardent UFO believers?
Yeah, the idea of Oumuamua as space junk is faintly plausible simply because not enough data is present to determine what it really was. And if somewhat-above-human level technological societies existed, they&#x27;d send out probes that would spend 99.9999% of their time as space junk so this might well the <i>only</i> evidence of alien life humans will <i>ever</i> see.[1]<p>But jumping from there to earth-based UFO is a serious mistake, since virtually all of these have been debunked and their claimed existence generally violates most basic laws of physics.<p>[1] This is just assuming nothing more than somewhat-above-our-level tech exists. And everyone assuming dramatic aliens essentially has assume things absolute impossible for our present tech. And maybe these things are just absolutely impossible.
