You don't need to be an 'investor' to invest in Singletrack: 6 days left: 95% of target - Find out more
I just listened to a long interview with the author of that paper about Oumuamua. If you have time and interest it's well worth listening to the whole thing.
They discuss what we know about the object, the reasons and methodology behind the suggestion of aliens, and why it's worth considering even if it's unlikely. There's also a new telescope due to be operational in a few years which should tell us whether objects like this are common and study them in more detail.
Sits back and awaits the standard meme

Just me?
Just me?
Nope👍
Cant see it or say it any other way.
Oh!
Awesme.
I like this kinda thing, cheers.
I wasn't posting this to claim we're being visited by aliens, you don't need to refute it 🙂
I enjoyed listening to a discussion of the science involved rather than arguments based on the clickbait headlines and unsourced Twitter takes.
I'm fairly certain there's aliens, would be a travesty if we were it. Problem is the size, radio signals have only been going out for 117 years, and the galaxy, never mind the universe, is 100,000 light years in size, so, so far our reach is about the equivalent of a 3 year old trying to hit san Francisco from Tokoyo with a pebble in intergalactic terms(probably even less than that). in universal terms, it's hard to even fathom the distance, 2.5 million lights years to Andromeda...
I've been probed...... ☝
Hope it’s not from Andromeda, Blake’s 7 didn’t fair very well against visitors from there.

but it's also very very old, so old even at low sub light speeds self replicating probes could have traversed the entire galaxy several times over.

Of what?
Alright mr pedantic! 😆 It'd be a bit shit!

I'd say it's more like putting a message in a bottle, throwing it in the sea and expecting someone to find it... and yet...

I know that theory, but couple of things with it, who says the universe is old in terms of life? It's predicted that the heat death the universe will occur in 10^106 years, so in those terms the universe is pretty young. Maybe we've just entered the universes life stage?
And as mentioned the galactic distances insane, so it's entirely possible it's already happened in another galaxy too, we'll just never know it, unless we learn how to fold space/time..

What would? 😆
😆
having seen a UFO I believe in aliens. Saw a strange round yellow light in Heathrow airspace once. Watched it for about 10minutes. It then slowly went into the distance.
I once jumped back in time about 30 seconds.
Standing at window, yellow Polo drives past, age of the train advert comes on telly with Jimmy Saville, look out of window again, same car drives past then advert repeats. Bloody weird and was obviously abducted by aliens, no doubt about it - they dropped me back 30 seconds early. Explains a lot, or so I'm told.
Don't remember much about the sub-light traversing, though I'm sure it happened, but slightly worried about the Jimmy Saville implication.
Went to see Brian Cox lecture tour last year (rock and roll!).
Interesting things to say about why we could be unique, why we probably aren't, and why we are really likely to NEVER know either way.

Shit....may will still be holding out for a deal in that timeframe
"Thanos" may well snap his fingers and half the protons in the universe will have decayed long before then 😀
