Back when Comet Holmes unexpectedly flared while in "Perseus' arm"
[actually in the asteroid belt area]... I emailed my brother [NASA
scientist/comet expert] about it and received two puzzling responses.
His first response was that he knows nothing [his typical government
response.] His second response over a week later [RE: Comet Holmes]
cced other NASA people and contained only a brief message to note the
second half of the essay and a link to a SETI article that had nothing
to do with Comet Holmes... but did [jokingly] mention aliens playing
havoc in Perseus' arm.
Here is that SETI article... it relates to your post.
btw... I also asked him about UFOs... all he would say is that I should be
more interested in what NASA did with all the elaborate quarantine equipment
used for Apollo.
a good link thanks, I read it all! The last sentence sums it up nicely and I quote:
" So while the cosmos could easily be rife with intelligent life – the architecture of the universe, and not some Starfleet Prime Directive, has ensured precious little interference of one culture with another".
