We cannot build one of those either. We do not what would give it a stable ecology and we do not know enough about biology to know how to keep anything healthy in space long term.Generational ship.

Not now, of course, but physics doesn't prevent it.The fastest thing we have ever made is the (unmanned) Parker Solar Probe which reached 0.064% of c.
We ain’t going anywhere at 99% of c.
If there ever is a generation ship, it will probably be a stable asteroid colony that we then strap a solar sail and some fusion drives to.We cannot build one of those either.

Maybe maybe not, who knows what the future holds but I think if we get stable asteroid colonies then we will get Oort Cloud colonies and then hopping to a neighbouring system may not need much in the line of special technology.If there ever is a generation ship, it will probably be a stable asteroid colony that we then strap a solar sail and some fusion drives to.
I also would not order contact but not for the reasons you provide. I am reasonably that human civilisation will survive, perhaps not any current one.So let's pretend for a moment that this is in fact the signature of life AND it turns out there there is a reasonably advanced civilization present. Knowing that it will take 124 years for a directed signal to reach them, and another 124 years to receive a reply, if any, would YOU, if put in charge, order contact? If so, how so and to what degree?
For example, given the serious nature of our impending environmental collapse, I wouldn't just order contact, I would start sending as much of our history and literature and art to them as possible (let's assume we could figure out how, including some sort of mathematical Rosetta stone) just to ensure that something of our civilization might survive us.
The Oort cloud is exceedingly empty, far more so than the asteroid belt. There is a lot of stuff there but it is a HUGE area.Maybe maybe not, who knows what the future holds but I think if we get stable asteroid colonies then we will get Oort Cloud colonies and then hopping to a neighbouring system may not need much in the line of special technology.
Probably, although that is why you want a hollowed out asteroid for a ship -- it can take a lot more high velocity impacts. Interstellar space is very empty, too. The chances of colliding with something larger than a grain of sand are essentially nil.I really doubt there will be high C starships, too much stuff in the interstellar medium and hitting a rock at that speed would be catastrophic.
But it is the current one -- you know, the one I live in -- that I want to preserve for posterity.I also would not order contact but not for the reasons you provide. I am reasonably that human civilisation will survive, perhaps not any current one.
This is a good idea, too. Also, there are a few geologically super stable points on earth that we should build massive monuments on for future civilizations.If you want aliens to learn of us, put the archive on the moon and perhaps other moons where they aliens that come here will find it.
If they have the capacity to get here, they don't need anything from us.Beaming messages into the void may annoy the neighbours. No one likes the neighbours playing loud music.
