None of that is really true. The stars are not at all hard to get to … at 300 km/s. Gotta be patient, and have a way to be stored or bored in transit.

Time frames are everything and in a million years or so a species could in theory spread out across the galaxy at sub light velocities. However in the threat scenario envisioned, our signals would take decades to reach them and an automatic hunter killer ship dispatched to dispatch us would take a long time to arrive. Objects can indeed travel between the stars over eons and one has to both accelerate to a reasonable fraction of light velocity, as well as match velocities with the system and orbit you wish to visit. Now if you could travel at a fast enough velocity time dilation could take effect and shorten your subjective time considerably after months of acceleration at 1G

I’d hate to encounter a golf-ball-sized rock at relativistic speed.

Or a grain of sand would at those velocities. An iron or gold ion passing through yer brain on the way to mars at near light speed would make an impression too and such things are spit out by cosmic forces losing their remaining electrons on the way to become a cosmic ray!

i don't think we're alone, but i think the speed of light is a brick wall, we're not going to go faster than the speed of light.
that would require either VERY long lived species, or generational ships, which pose hosts of problems, both technological and sociological.
we're in a pretty remote part of the universe, relatively speaking. i think the best we might ever do is radio communicate with other species, but if they've been listening to what we've been broadcasting, i could see why they're not that interested in communicating with us.

I think the answer is simpler. It doesn’t require we be aware or active on the long slow trips. Store life and mind in digital form, and send a few von Neumann machines along to build the physical substrate. The necessary ships would be quite small and robust, and quiet.
also, I imagine the big boys communicate using a tech we have not yet even imagined.

i don't know, i can imagine a lot...
what i usually have trouble imagining is why anyone with that kind of technology would want to come stare at violent hillbillies killing each other and shitting where they eat?

… the same reason people get into ant farms and pet reptiles? (or, for a scarier metaphor, bonsai?)

Maybe quantum entanglement, but ya would have to move one of the entangled particles or a bunch of them to where you wanted to send or receive the message. Even then I don't think theory will allow information to travel faster than light. But what is information? It contains no mass as in a laser beam carrying communication in space. Anything with mass cannot approach the speed of light with out being on an atomic level and being pushed and or pulled very hard by cosmic forces. Anything like a spacecraft would need a tremendous amount of energy to get to a small fraction of light speed, we are talking about matter antimatter levels of power density, not mere fusion.

that's a long way to go to look at ants...
i can't even guess what the motivation would be to go to a minor arm of the milky way in the middle of nowhere, just to observe us...if you could go anywhere, why in the hell would you come here? human vanity, we just think we're so fucking interesting...

you find our antics amusing? i'm disappointed and disgusted, for the most part.

It is not beyond imagining that, for reasons not known to us, our little corner might be the stuff of galactic postcards and glossy calendars. And that the garish stuff (gamma-ray bursters, supernova imposters and colliding magnetars) occupy the margins of their kids’ notebooks in the same way that human boys will draw supersonic attack sharks and T-Rexes with machine guns.
well whaddyaknow.

Sounds like evolution to the internet..only government, tech and corporate..a monitor with movement 1991 Radio Shack at the mall..1995 you've got mail at AOL.2000 tap, tap and more tapping of Palm Pilot..if only we could put all these devices together? Sometimes you have to be careful what you wish for..2007smart then FB and now it's all weaponized.Someone stupid is in very deep shit with the FAA, no pilot's license either I'll bet. This is why there are crippling regulations on the hobby and industry, they can be used as weapons of war too. It used to be you had to build your own, then commercial ones became available and they were easy to fly with flight control computers making them accessible to morons too.

A big city New York lawyer went duck hunting in rural Texas. He shot and dropped a bird, but it fell into a farmer's field on the other side of a fence. As the lawyer climbed over the fence, an elderly farmer drove up on his tractor and asked him what he was doing.
The litigator responded, "I shot a duck and it fell in this field, and now I'm going into retrieve it."
The old farmer replied. "This is my property, and you are not coming over here."
The indignant lawyer said, "I am one of the best trial attorneys in the U.S. and, if you don't let me get that duck, I'll sue you and take everything you own."
The old farmer smiled and said, "Apparently, you don't know how we do things in Texas. We settle small disagreements like this with the Texas Three Kick Rule."
The lawyer asked, "What is the Texas Three Kick Rule?"
The farmer replied, "Well, first I kick you three times and then you kick me three times, and so on, back and forth, until someone gives up."
The attorney quickly thought about the proposed contest and decided that he could easily take the old codger. He agreed to abide by the local custom.
The old farmer slowly climbed down from the tractor and walked up to the city feller. His first kick planted the toe of his heavy work boot into the lawyer's shin and dropped him to his knees. His second kick landed square on the man's nose. The barrister was flat on his belly when the farmer's third kick to a kidney nearly caused him to give up.
The lawyer summoned every bit of his will and managed to get to his feet and said, "Okay, you old coot, now it's my turn!"
The old farmer smiled and said, "Naw, I give up. You can have the duck."
The litigator responded, "I shot a duck and it fell in this field, and now I'm going into retrieve it."
The old farmer replied. "This is my property, and you are not coming over here."
