truly brilliant .

y'know....I read a great book on quantum theory..and in it was the theory that since we affect change simply by observation at the sub atomic level...and that consequently we also have been affecting the development of our universe around us significantly as well...
and the postulation was that we may very well by our observations be doing far more harm than Dave's misinterpreted Black hole ...on the universe itself...causing cataclysms on uninhabited planets, regions, and inhabited planets throughout the universe...
Freaky....that we may have , are or possibly will be inadvertently destroying alien inhabited civilizations without even being aware of it directly ...
Dave would be so upset by this so don't tell him...

It would explain past Alien sightings ...and the recent "debris" of the light sail called "Oumuamua".....
it may very well have been part of a ship full of alien dignitaries headed to Earth that were inadvertently exploded before arriving ...by some child in South Wales casual glance and thought ...while having an ice cream cone.
