    He's basically right. The universe is so large, and so old, and the chemistry of life is literally spread between the stars - of course there is life out there, and intelligent life too.

      @@VaraLaFey The amount of head start and the speeds necessary to catch up greatly exceed anything we have currently done or even have on the drawing board, and would require nuclear power. I fully support nuclear power in space, but it has problems (mostly social caused sourcing difficulties, but that's another problem).
      What it MIGHT be able to do is get in a position to be able to see it, if it's were its last known trajectory indicates it should be. If it's not there -- most likely -- it will probably because of all the known and unknown gravitational influences. We've known since Sir Isaac Newton's time the 3-body problem is insolvable and space is infinitely more complex than a mere 3 bodies.
      If we can get it in our sights, with our improved optics maybe we will finally at last know what it looks like.
      The money such an effort would require could be spent sending a bunch of small, programable (hopefully nuclear powered) voyager-type craft to patrol the asteroid belt. The next time an interstellar visitor is seen approaching, the nearest asteroid-patroller would be sent to get close -- perhaps even land on -- the incoming object.
      If we officially know of 2 interstellar rocks within the first 20 years we have been able to reliably identify and see them, there must be many such. Asteroid patrols have a nearly 100% success probability.

      ​@sentientflower7891 I almost said, "If it takes them thousands or millions of years to get here, their time here could be considered a visit even if they stayed here for for a long time in human terms." But even the New Horizons spacecraft could get to Alpha Centauri in 80,000 years, so the minimum time for interstellar travel for an advanced civilization would certainly be less than 1,000 years. But yes, some trips could take millions of years.

      @@stevedwyer8333 New Horizon cannot get to Alpha Centaur in 80,000 years. That's not how visiting another star system works. If you want to attain orbit around Alpha Centauri you can get there in a thousand years but you will have to slow down in order to attain orbit around the star and that maneuver alone will take 100,000 years.

      @@realsydney7327 Your first remark was a fallacious appeal to ignorance. You conclude that life external to Earth is not possible because it hasn't been proven conclusively true. Loeb's arguments are largely probabilistic based on possible interpretations of accepted evidence. That doesn't make them true, but he is a scientist hypothesizing and looking for additional evidence. Your second response is also fallacious reasoning. You cannot conclude that absence of evidence is evidence of absence.
