    I think that cockroaches are extraterrestrial. Thats for sure. If you cut their head off, they died by inanition in a few days. That is horrible! And also they are intelligent, they leaves you in peace when they want, not when you want no matter you use poisson or not. :smile:

    The best proof of extra terrestrial intelligence is that they never contacted us...

    Energy shortage?

    Any advanced alien civilization which had enough excess energy to build a 'Dyson Sphere' would certainly not need to build one to get more energy.

    You may mistake a Dyson shell for a Dyson "swarm" of satellites. The later could start in the near future. One could argue that the first satellite using solar power were the first part of a Dyson "swarm".
