I believe there is a plan to build a self-repairing solar sail underway, which will provide a possible form of propulsion for our future probes.  Whilst a great idea, I believe this highlights a problem we are going to have ourselves, as a species,  that the ability to build better spaceships is possibly going to outstrip the ability to develop trans-galactic communication systems, which will ultimately defeat the concept. There is no point in sending stuff across the cosmos if we cannot get anything out of it.

So, we will either have to develop communication relay-stations, or spaceships that come BACK with information, both of which will be a major drain on our current interstellar resources.

To go back to the original discussion though, I think that the other possibility, of motherships capable of supporting a species in its entirety, is a more rewarding way to explore the universe. Once a species has evolved means to both anticipate and deal with the potential hazards of space-travel whilst building and repairing at will, then there is almost no limit to what they are able to do. It's one possible solution, I think.

The other solution is the one we have not yet discovered, thought of, or perhaps never envisaged - the easier way to get around space, whatever that is. :D  Although the human species is currently stuck in the realm of thermo-nuclear physics and various other forms of propulsion, I'm assuming that within another 1000 years we will have other options, many of which no one has yet thought of.

That's assuming we are still here of course. At some stage one race on earth is going to have to pull their weight and become top dog to avoid a complete meltdown of everything on the planet,  and I do not think that is either going to be pretty or leave a lot behind that will be of use to a species.

Maybe for the exact same reasons you listed in your previous post?

The more simple the drone, the less likely there will be errors in reproduction.

Here at Intel we make processors on 12 inch wafers. And, the individual processors on the wafers are called die. And, I am employed to check these die. That is why I am the DieChecker.

We have been in the situation where ships were our only means of communication between the mother country and her colonies.  It is for this very reason that the bttle of new orleans took place, six weeks after the war was over.

There are other mormons on this site. So if I have misspoken about the beliefs. I welcome their input.

If an alien civilization did create self replicating probes I sure hope they didn't give them the ability to make self improvements.  It is not hard to imagine that going horribly wrong if those probes became self aware and decided that biological life posses a threat to their existence. :no:

When you throw in the exponential growth factor, it would not be long before they became stronger, smarter and faster than anything we can imagine or have any hope of defending ourselves against.

true Badeskov, it's more of an immediate inference than a paradox,
as it only references its own answer rather than attacking it, but i guess "that thing that Fermi bloke said about aliens" didn't have the same ring to it!

I think if you sent probes out into space, you would want them to evolve for new situations Unknown facters.  Self programing drones.

This could be a good idea, too. Wouldn't whoever sent out the drones want to gather as much information as possible about a distant planet's biology? That biology may be of an unexpected order, and the drone may have to alter its expectations of what it considers life to be.

The way I see it.... We can barely detect a quarter mile asteroid flying by, much less some silent, small alien probe that might be watching us with superior optics.

Here at Intel we make processors on 12 inch wafers. And, the individual processors on the wafers are called die. And, I am employed to check these die. That is why I am the DieChecker.

If there is a system that is so harsh it destroys the drone, it is probably too harsh for colonization anyway, and thus mostly useless. I'd keep a drone simple. I'd even use very primitive technology, the bare minimum, as I'd not like good technology to fall into the hands of anyone out there who happened to capture it.

Or give it selfdestruct option if it is picked up. The five drones that we have leaving the system has out of date tech on them.  New horizen has the most advanced tech on it.  The other four have traveling since the seventies.

Ask almost any astrophysicist you might happen to find walking down the street and the first you will hear from them is, "Fermi's Paradox."  (If you want a real expert you will need an exobiologist, but as these are getting rare they can nowadays and be found only with difficulty on campus).  

The whole idea is now pretty much rejected except among a few die-hards that have forgotten the first rule of the Scientific Method (check the literature) and the idea of all the visitors is pretty much laughed at now in academic circles and we are close to alone out there and that the universe is ours for the taking.

Sorry, it seems much less exciting at first but in the long run it will make for a far more interesting universe to see how we evolve, and maybe we will run into a few others that we can learn from and cooperate with.

Or as the traveler on next generation said, we aee just not interesting.  Also in first contact,the vulcans only stopped by because of the warp test, ie our tech was good enough to interest them.
