would unironically be the best thing to happen to america in decades. i think we need a collective bad guy in china so we can stop being faggots and fighting with each other. right now nobody gives a fuck because it's all projections about how they're going to overtake us in the future and we're mostly shortsighted retard monkeys that don't care unless it's happening right now

>How would we go about terraforming Mars?

Can't. Atmosphere's too thin, there's not enough gravity to sustain one if you somehow built it up, and no magnetic field to protect it from the solar wind blowing it away.

Leave that sad-ass little planet alone, like it belongs. It sucks.

>....because they have existed much longer in human evolutionary history, Africans have more mutations in their genomes than other races.

What the shit?

>And the mutation loads significantly decrease physical attractiveness...

So this asshole literally makes shit about by saying Africans have more genomic mutations and then goes on to say genomic mutations and physical attractiveness are negatively correlated.

Reminds of the time when I was taking a psychology course (forced) and the prof went on about how western societies were more civilized than african ones.

So what? An extremely small amount, thorium reactors are extremely safe and self restrictive.

Better than Uranium reactors, and more achievable than fusion and renewable.

OP there is already the Venus Project movement with Zeitgeist, this is the best and largest resource based economy movement.

So, I hear that the universe will eventually freeze over because of the fact that there will be no more heat left due to expansion. Doesn't that make everything we are doing now a bit futile? Is there a conceivable way we could "escape" the particular universe we are in before that happens?

simple geometry for you /sci/

you have 3 noncollinear points.

how many planes can those 3 points be on?
keep in mind you need 3 points for a plane.

answers:

a) 1
b) ∞
c) neither

First part of my question, is salt water healthy for your skin?

Whenever I take a vacation down to the Adriatic Sea, I'm spending like two hours a day (for a month or so at a time) in salt water. By the time is over, all of my skin problems are gone, and my skin just looks and feels healthier, as opposed to when I'm on vacation and not in salt water, my skin isn't any different that in the middle of winter while in school. Well, except tanner.

Now for the second part, why don't we just use salt water, instead of wasting fresh water, for washing and showering?
