Grand-Scale reasons to Explore Space: How we all benefit

[ajn158]

We will go into space, the reason is simple. Entropy & Economics.

We refine minerals to create products, but the products (generally) have a lower concentration of the minerals than the original ore. The lower the concentration of minerals, the higher energy costs to refine the minerals.

It wont be much longer before mining our solar system will be cheaper (use less energy) than recycling (of rare minerals).

I agree, in a country that spends more on "National Defense" than every other country in the world combined, the military budget could be shrunk by anywhere from 10-25% and still suffer no ills and be no worse for it. That money could then be redirected to our education programs and yes space programs too.

Ignorance is a key contributor to a lot of our national and personal problems, education can help fix that.

Excellent point regarding guilt.

There are people starving across the world but decades of foreign aid has only succeeded in making many countries (predominantly in Africa) virtually dependent on US grain excesses.

Birth control pills, condoms and education would be cheaper and have a much more far reaching effect.

It is not up to US or European citizens to solve other country's problems. Help and advise them yes, donate for specific disasters but not year on year, and then quit worrying.

The debate is usually manned space exploration vs unmanned...

Pride in accomplishment for the win!

I think Cameron was making more of a statement about humans, not about technology. Though I haven't seen the movie, I've seen an interview with him and people who liked Avatar generally point to the character played by Sigourney Weaver as a model of a 'good scientist/scholar'. Other than that, great video.
