I always thought an interesting experiment would be to fire off a handful of nuclear bombs in space. (Rather deep space, like well out of where they could do any harm to Earth.)
Then pace the time between detonations to different prime numbers...
This is a core point in the Three Body Problem series of books by Liu Cixin (plus a little hand waving sciency signal amplification). As mentioned below it turns out to be a generally bad idea
Relative to the speed of light, where these effects actually become appreciable?
Yes. Hell yes. Basically identical velocities. Signal to noise ratio issues will do in this idea long before relativity has any sort of impact; it's not even close.
Not really that deep at all, it turns out you can fire off nuclear bombs above about 80km up and they are essentially harmless to life, causing only electrical (i.e. EMP) effects.
Wouldnt 'they' have evolved 1000 yrs as well? By that time their own current state of evolution would look even less developed given the exponentiality of evolution.
Perhaps we just need to stop being dangerous to other species and ourselves. Embracing the pursuit of collective goals would be a huge advance in our civilization level. Beyond that point athough less developed we could be accepted for not being harmful anymore.
no.. you're assuming that other species develop technology at a similar rate, and that our current progress will continue at the same rate. Both are things we don't know.
There may be hard limits that stop development of technology past a certain point. Like Moore's law coming to an end, but one day we may not have any viable alternatives.
