The interstellar object 3I/ATLAS is scheduled for its closest approach to Earth on 19 December. Harvard physicist Avi Loeb warns that if it turns out to be alien technology, humanity absolutely has no protocol for a potential encounter.
Loeb speculates that the celestial visitor may not be a natural comet due to its anomalous behaviours. Observers have noted its movements 'could differ from those observed in conventional comets', leading to theories regarding a 'non-natural origin'.
