Why doesn't NASA, now with its high and mighty objectives, re-uptake and revive project Orion?

It seems like the only good way to get to Mars and the moon and start colonizing right away to me. For those of you who do not know what project Orion was:

http://en.wikipedia.org/wiki/project_ori...

A 1950's project of using nukes for space propulsion.

It was not used due to the cold war and the tensions it would cause. The secondary reason is fallout. However, my reasoning is as follows: If you launch just 2 of these vehicles, you have all the material to start independence from earth and colonization activities in space…so…the amount of fallout from just two vehicles…would just amount to a few nukes…which have been dropped throughout the 20th century….

This would not put that much extra radiation into the environment, but supply enough of a payload to start large-scale activities in space…catch my drift? It may even cost less than slowly putting material through hundreds of rockets…

why can nothing go faster than the speed of light?

i understand Einsteins theory of relativity, how its impossible to travel faster than light because the energy used is leading up to infinity, but why is it that 2 objects traveling towards each other at the speed of light only pass at the speed of light rather than twice the speed of light?

Why does SETI seek radio signals when advanced civilizations would surely not use them to communicate?

Truly advanced civilizations would have unravelled the mysteries of quantum physics and communicate over that medium, not using primitive radio signals. The chances that we would happen to catch another civilization which happens to be in the few hundred years of their evolution where they are using radio signals are very slim indeed.

No wonder we hear nothing. If we had a device however that could hear transmissions over the quantum medium, we would likely hear endless chatter and be able to watch alien TV shows.

Thoughts?
