Grim Jim Posted December 10, 2019 Share Posted December 10, 2019 Quote Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space. Quote Link to comment Share on other sites More sharing options...

Obviously we haven't observed any yet, but the numbers mean that there are an unbelievable amount of chances for life to form. It would be mathematically surprising (to say the least) if Earth was the only place it happened. One of the key factors for intelligent life or advanced scientific civilisations though, is how long they'd last. Would it be in the nature of these societies to destroy themselves? Let's face it we've come close and we could only consider ourselves in that category for less than 100years. Quote Link to comment Share on other sites More sharing options...

I'm not convinced that the definition of intelligence is correct if allows us to destroy ourselves. Maybe we get a wee inkling and then just think, "fck it".

biffer Posted December 25, 2019 Share Posted December 25, 2019 Incidentally, wrt the Fermi Paradox, there's a whack of interesting stuff about the great filter online if you go and have a look. Have we passed through it, are we yet to approach it, where in the evolutionary chain would it hit. It's worth remembering that it took two and a half times longer to go from single celled life to multi celled life than it did to go from the first multi celled life to us now.

biffer Posted January 22, 2020 Share Posted January 22, 2020 24 minutes ago, Dave78 said: What, you mean like Skynet? Fortunately, no. It might turn out to be something called an instrument artefact, which is basically a way of saying 'this machine does that sometimes'. Although it seems fairly unlikely in this case, given the signal was detected on all three LIGO instruments in separate locations. The exciting thing is that there's been nearly a hundred years of people proposing mechanisms for producing gravitational wave signals (black holes collapsing, supernovae, neutron stars merging) and none of them have predicted a signal that looks like this one.

thplinth Posted February 4, 2020 Share Posted February 4, 2020 A heap of balloons all tied together into a ball is my usual go to explanation so it is definitely possible here. Also it is hard to tell if it is moving that fast or whether it is the plane passing it. Quote Link to comment Share on other sites More sharing options...
