Harvard Professor believes Earth (in 2017) was visited by alien artifact

Harvard Professor of Astronomy Avi Loeb has written a book, Extraterrestrial: The First Sign of Intelligent Life Beyond Earth that theorizes that Oumuamua which sailed through our solar system in October 2017 was actually an artifact from an alien civilization, and not an comet as the majority of scientest believe.

In his book (scheduled to be released 26 Jan 2021) Loeb looks at why he thinks the Oumuamua was from an alien civilization and what implications it could have.
 
Such a cool thing to read about. The trajectory looks far from accidental.

They missed Matt Damon on Mars, but swung past the rest of the Small Kids on the Block. ;)
 
I don't doubt for a minute there are extraterrestrials and there are parts of the galaxy far older than ours. If they have come to visit/study earth it means that FTL space travel is relatively easy and cheap when you have the right technology, as we are not exactly in a centre of the galaxy and not lot else out here.
 
Maybe they found the readings sent back by the first too bizarre and are sending a follow-up.

'They can't be that nuts, can they? Act cool and keep the doors locked.'

I have to believe that there are advanced civilizations out there. The Drake Equation (admittedly flawed now, especially as discovery of the variability in the universe and the number of known systems with exo-planets rises) predicted large numbers of potential sentient species (well >1000) in our galaxy alone. The Fermi Paradox attempted to find out why we haven't heard anything from them yet. To me, the probable answer is that there's a good chance nobody knows we are here. The first radio signals with enough strength to leave our atmosphere and radiate outwards started in the 1940s. That means at most, they could be ~80 light years distant, but probably with such little energy as to be indistinguishable from background noise.

The Sci Fi nerd in me wants to see some sort of answer, but I doubt it will be in my lifetime.

They've been here all along. At first they tried to find about us by individual contact/abduction and "probing". But as they found it inefficient to compile a database in that manner, they introduced a more efficient and surreptitious method - colonoscopy. From initial use in 1969 to the mid-1980s, it was just a trial. Then they started the campaign in earnest aided by a fellow traveller in the White House; the publicity surrounding the 1985 colonoscopy of Ronald Reagan removed the hesitancy of many to voluntarily submit to the procedure.



Why do you think that the recommended age has been decreasing from 60s with an underlying clinical requirement to age 45 as a screening procedure.

I would generally agree that there may be extraterrestrial life, but I think that once you examine the proposition by way of the Fermi paradox, the likelihood becomes astonishingly small. Additionally, for any civilization to have visited us in any practical sense, would require travel at superluminal speeds, which according to our understanding of science, breaks Einstein's theory of special relativity, which establishes the speed of light as the maximum. That is not to say that I don't consider the prospect of non-relitavistic physics that allow for increased speed without increased passage of time (external to the traveller), just that I consider it unlikely.
