The idea of gravity waves was theorized then, that's hardly proof considering that's what your whole point. Concrete proof.
Your opinion is totally fine and might be accurate, its just interesting that we both consider there is life out there, but the species that sucks at space travel lay down all the ground rules of what's possible for space travel. lol.
It's the bizarre mix of ignorance and arrogance and how we refuse to look at how wrong we've been over and over and over again.
I dont think we have ever said we know all of the answers and know everything about space travel to even start laying down the rules of space travel, however, we do experiments every day testing theories, looking for new methods, increasing our knowledge and we can only go off the results of those tests as to what 'we' deem as possible at this time.
It isnt arrogance its the not knowing part (yes, scientific ignorance) and we are constantly learning more and more about how everything works through science. And so far theoretically NOTHING can come even close to the speed of light (a large object such as even a drone) using the knowledge we have. Is it possible, yes, is it improbable? using current knowledge, yes.
Its all well and good saying but thats our knowledge not some theoretical extra terrestrial species with knowledge 1 million years beyond our own, yeh, great, and that knowledge is pathetic compared to the mystical space whale which can instantly appear at any place in space time through manipulation of time and space through its blow hole.
Until extra terrestrials appear and share knowledge of how to travel faster than light or bend space time through localised worm holes (or we eventually figure it out ourselves) then we can only go off of what we know through constant theories, experimentation and testing.
And like I said, its not beyond the realms of possibility that we are indeed unique (not saying we are by the way, just that it is possible, it goes both ways this opening you mind thing)
Anyway, keep them coming, very interesting conversation, we usually have these conversations at 2am slightly inebriated.
