I saw a TV program where Americans were trying to make a danger sign that civizations in the future (after the collapse of our own) would understand after nuclear waste was to be buried in an underground salt mine. Did they make one. If so what was it.

From what I've read, there seems to be some contriversy as to whether or not the Oort Cloud is actually out there. I guess it would make sense that something like that could exist (afterall comets have to come from somewhere) but shouldn't we at least be able to detect it somehow? I know that (if it exists) it would be very far away from Earth and would be very very faint, given the fact that it would just be a loose band of comet-like objects. But still, with all the powerful telescopes and infrared devices we have at our disposal, why haven't we been able to authenticate it's existance?

Why i put it under science cause its a respond to will teachers eventually catch thier students using yahoo answers to cheat?
where mr jeffy said,"The students who 'cheat' by having others do their entire homework assignment for them online don't learn anything"

Why do people like mrje(youknowwho) think that its useless that you get answers and understand the concepts from there?

I feel that its an important step of learning which copying and by that understand the concepts of the questions which should be present in a normal question. Every question has a concept and I feel that by even copying, he or she learns something out of it instead of not doing and I don't understand mrjeffy's viewpoint so can anyone explain to me?

Ok I must state again that I am not insulting mrje(youknowwho).
