RE: The Von Neumann Problem - Where Are All The Aliens?
"I for one believe that interstellar travel is very difficult"
That was the sum of my thoughts, and I learned something new here, as I never thought about Fermi's paradox. I feel a little slow.
Undoubtedly, there is life out there.
Does the fact that everything has been getting further and further apart since the Big Bang have any relevance? Or is that effect too slow, in comparison to the speeds vehicles could travel through space?
Thinking about Fermi's paradox, it would seem that the wormholes so prevalent in sci-fi, as a means to travel intergalactically, must be impossible to create, and must not exist naturally, at least as a means of facilitating travel.
While I think the human race will ultimately encounter aliens, I doubt it will happen in my lifetime, as if we haven't met for the last 6 million years, the chances are we won't meet for the next 6 million years. :0
Yes and no, yes because distant galaxies are flying away faster than the speed of light, and no because the effect is negligible for closer stars and galaxies, in fact we are going towards Andromeda and will collide with them in about 2 million years I think.
Possibly, or they simply haven't been created in order to visit us; or the aliens that have created them to visit us, are so far in advance of us, that they believe there is zero point communicating with us. Rather like us going back 6 million years and seeing our common ancestor, sure we'd observe, but there would be no point trying to talk to them.
I desperately hope you're wrong, but fear you may be right :-(

Don't lose hope. Maybe Stargate is the literal truth, and the ancient Egyptian Gods were in fact a visit from aliens, who pushed our primitive ancestors about with alien technology.
Perhaps, they'll be back to give everyone a shock lol.
Or perhaps the black monolith from 2001 will turn out to be a thing, and show up again in 2021, and before we're 60, we'll all evolve into Supermen.
Maybe David Icke is more scientist than fantasist. Or perhaps that last suggestion is a step too far. :)
Lolz, I'm just hoping it's going to be like Star Trek First Contact, whereby we achieve some amazing space travel feat and then the aliens say, OK cook, now we'll talk to you.
Damn, where's that straw I was clutching gone?
:-D
