In the short term, that is what happens.

Think long term.

Where do the CEO's get their money? By selling products. Where do the products come from? The robots.

So who is buying the products?

Oh whoops, it can't be the general population - none of them have any jobs!

Capitalism (The current form, at least) is going to shoot itself in the head as it embraces autolabor. I've got the popcorn ready. It's going to be a wild ride.

If you're for equal rights, then you're an egalitarian.

I guess people just prefer 'feminism' because it flows better than 'egalitarianism'.

The tube is not completely filled. The mercury sloshes around inside of it.

You sound like my kind of girl.

What we should do is increase automated labor and put everyone out of a job.

The problem with eugenics is that it very quickly and commonly devolves into "Anyone who is not like me should be exterminated".

>a power supply (The Moon takes too long to rotate -- Land on the Peaks of Eternal Light?),

Not a terribly difficult issue, actually. Solarsats in orbit would be good enough, just beam energy down to the surface of the moon at a rectenna. Don't even have to worry about any atmospheric losses or cooked birds.

Space is able to expand faster than the speed of light.

Mass doesn't change, density changes.

You could collapse the Earth into a black hole, the schwartzchild radius is something like the size of a hamburger. It wouldn't change the Moon's orbit or anything else though, because the mass is still the same.

>Couldn't you store an equal amount of both anti-matter and matter and then annihilate them on demand,
Yes, indeed you could.

>and then store the resulting energy with a battery for use?
No. Well... you *could*, but let me paint you a picture: 0.5 grams of matter coming into contact with 0.5 grams of anti-matter would produce an explosion with an approximate yield of 15 kilotons. We're talking, nuclear bombs here.

Needless to say, this isn't something easily stored. Sure, you could scale down to something manageable (micrograms, nanograms), but there are other issues, not least of which that just storing the matter/anti-matter is lighter and more efficient than whatever battery and energy extractor you might want to use instead.

>Wouldn't the enormous energy density of anti-matter allow you to power very power-hungry devices in a light package? Could this 'anti-matter reactor' be placed in a small vehicle?

Yes. This is one of the big things about matter-antimatter that makes it so attractive, especially for spaceflight. You can do some very crazy things with anti-matter drives that are simply not practical with other engine systems.

Giant hoola hoops in space

Furthermore, it's illegal in the states because of Jimmy Carter.

The issue is that reprocessing plants can be used to create weapons-grade material. So Jimmy Carter made these plants illegal.

France currently utilizes a wide range of different Nuclear Reactors to burn and reprocess their waste.

It's called Nuclear Reprocessing

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

You take dangerously radioactive 'waste' from one reactor, and burn it in another reactor.

Keep doing this until you can no longer get enough energy out of the 'waste'.

What's left is a small fraction of the waste you started with, and it will only be dangerously radioactive for a couple hundred years instead of thousands or millions. Because there's so little waste, it's also easier to store.

If we uplift them to human levels of intelligence, we'll let them vote, right?

Same for robots with human level intelligence, right?

An enlightened society like ours wouldn't treat them like slaves and cattle, would we?

This isn't psychohistory.

Psychohistory was taking what was known about humanity, how people in general tend to act and behave, and then making predictions and mathematical models based on that.

This is running a pile of RNG's and correlating odd results to specific events.

I do pretty much the same. Just basic bodyweight exercises every day.

It's not much, to be honest, only 10-15 minutes worth.

Most forms of mercury you'll come across are safe enough to ingest.

The body does not absorb mercury very well.

This is where I live.

Perpetual motion does not work because it involves violating the laws of thermodynamics.

These laws can be summed up thusly:
You can't win, you can only break even.
You can only break even at absolute zero.
You can never reach absolute zero.

That is what caused the program to be canceled in the first place. You make it sound like this is a new thing, but it isn't. We haven't been legally able to detonate nuclear bombs in space since 1963.

Project Orion, by the way, started in 1958.

>The summary is (if I am not mistaken) that us humans are not fit enough to go into space. We must first fix our Earthly problems first and later consider going deeper into space.

No, that's just trolls and logical fallacies.

We do not need another 20 billion dollars to keep the world fed and cure cancer. That is not how reality works.

Not me. I love NASA, but I'm glad to see the waste of money that was the space shuttle go.

I suppose that really depends on how you'd define a planet. There's already a dwarf planet in the asteroid belt called Ceres, and it comprises about 1/3rd the total mass of the belt.

Nuclear bombs when detonated in space still emit an incredible amount of electromagnetic energy. Detonated close enough to an asteroid, or any other object, they will flash vaporize the surface of said object, it may even create enough thermal stress to crack the material or cause thermal shockwaves within it. The flash vaporization essentially pushes the object away from the nuclear explosion.
