At least 3 million years are required to form a geological strata (of say 7 ft?). What
remanents of a culture might survive? Plastic pieces; or nothing at all? Our world has
hundreds of tons of plutonium; plus all reactors forming plutonium. The halve life of
plutonium is very long; so it would survive on our planet, and in our broader stellar system
if for example we diverted an asteroid by nuclear warhead means. Likewise for exploration of
terrestrial planets of habitat zone of another stellar system, might the only trace of
civilization be that of plutonium? Stars form in multiple; so therefore our Sun has sister
stellar systems, very close, and ascertainable via dedicated infrared telescope detection of
'cold' gas giants. In addition to spectroscopic detection of oxygen (sign of photosynthesis)
in the atmosphere, might search for plutonium be of interest?
