    What I want to know is how these things would communicate over such large distances. Radio? Laser? Would you need a string of relay stations to boost the signal? It seems impossible to me to get a reasonable bit rate with a 1 gram spacecraft!

    My recollection is that we have an old thread on just this point. The plan is to relay but the bit rate is awfully low for any sensible power scenario..

    What if another civilization did the same thing and sent these tiny probes here and they are in our solar system monitoring us, we would never know.

    Well from the POV of the communication problem, THEY wouldn't know it either.

    Maybe the answer could be found in some type of sacrificial barrier in front of the craft? I know they touched on that with the beryllium, but I'm thinking something in front of, not attached to. Or maybe a nano technology that repairs the damage as it occurs?

    How would water stand up to these impacts?

    Just my thoughts.
    In that case Stephen Hawking's belief that we should keep our heads down to avoid detection is wrong. And yet he believes in this technology, which seems rather inconsistent to me!

    Water would stand up fine but not be as effective as other shielding.

    Nanotechnology repair delivered in a circulatory system might be good. Hmm. Maybe a bug?
    chas53, helicon64 and Murphy625 like this.
