Ah, but following your logic the time traveller would influence infinite futures by changing that one frame, creating an infinitely high probability of affecting the future we live in.

Close your eyes. Take a deep breath. Relax.

I'm pretty sure that the Planetary Resources guys got it right. The only way to really lower cost for all these projects is to produce all heavy mission components as well as fuel in space, outside of earth's gravity well.

What is Helium 3 good for without a viable fusion reactor to process it?

That's the spirit.

You must have a very tolerant work environment.

Probably domesticated in Afghanistan, some sort of co-evolution or something.

Cats are weird, aspirin is toxic to them too.

No clue what you are talking about, your comment has nothing to do with what I wrote. Building strawmen might be entertaining to you, but answering them? Not so much.

So that oil is basically fish-food, correct? Maybe it even has electrolytes!

What are you trying to say with 'oil is an organic substance'? If you mean 'organic compound' then plastic is just as organic.

That makes no sense whatsoever, do you realize that? How would one measure a quality against the variation of same quality in the total sample? Your result will always be '1'. Level of human stupidity compared to average human stupidity? 1.

'Xactly. Thanks for the link.

We are the only species that knows better. Actually we are the only known species pondering moral and ethics or caring for other species. We might not be perfect in that regard, but we get better constantly.

Compared to which other species?

i remember a very reasonable proposal to do colonization missions to Moon or Mars as one way trips, with 60+ years old crew. Could dramatically lower costs, no return infrastructure, radiation shielding not so critical, etc..

It's not about risk/no risk, its about resources vs. risk profile. In other words, how much resources are to be invested in order to lower risk. It's an exponential function, you'll never achieve 100% safety, but the safer, the more expensive, exponentially so.

I didn't 'call Americans a race', guess you misread. The whole race-concept is extremely dubious anyhow, not only in terms of political correctness, but as a classification system.

Just curious, how does that quip get any more racist by substituting 'Americans' with 'Irish'?

You're kidding, right?
