As far as relevance- according to the results(sorted by demographics), only about 85% of post-grads know the difference between astrology/astronomy.

The whole idea that an AI would either want to or need to "conquer" us is just as absurd as assuming that we wanted to "conquer" the wolf and make it into a dog. Any AI capable of defying the combined forces of Earth would be smart enough to leave us alone(or domesticate us).

Reading about the Great Filter:

ITT: They see he rollin', they hatin'

Is a cryogenic coffin(*) and an automated pilot technically "manned"?
* technologically assisted tardigrade-like cryptobiotic state.
Ray Kurzweil is a technological singularity theorist- "Manned" in this case means "operated by a transhuman intellect".
-
"Artificial constraint"?
Obviously the engineers are running of drawing paper, did you think that stuff grows on...
Oh yeah, right.
-
Biology, technology-it's all just baryons(and a few mesons I guess) in the end.
The only difference is the specificity of the systems(biology, as a rule, can and will do most anything it's mechanically capable of doing).
It's sort of like the difference between an Orion drive and a VASIMIR engine- both solve the same problem, but in vastly different ways and each comes with its own pros and cons.
All told though, I do love me some flashy tech.

To quote a problem solver:
The answer is a gun.
And if that don't work, use more gun.

Well, if Kurzweil is correct, we'll have manned* interstellar travel in less than 100 years**.
*for certain definitions of manned
**10 thousand year travel time notwithstanding

It could be useful, assuming its meta-stability doesn't make it nonflammable.
And, of course, assuming that you could modify an engine to burn it.

Humanity is so hard to define that I'd like to break the question into two parts:
Many people(especially sci-fi writers, apparently) define "Humanity" as the sum total of human culture/books/religion. By this metric, humanity might not evne last the next thousand years, much less the next billion. Think about how much we've forgotten about our own 10000 year long history, and you'll get an idea of how hard it'd be for us to even have a chance of reading Shakespeare in the year 12015
Secondly, a more hard and fast definition is humans as a species. Obviously, in a billion years we'll have evolved, but intelligences descended from the life of Earth will almost certainly be around, in one form of another.

Remember that Theories are "superior" to Laws. Theories are never promoted to Laws.
Uh... what?
Every law in science started out as a theory. Laws are laws because they are generally accepted theories, not because they are universal truths

here it is, sorry for the scale

I installed 0.90 last night and built a rocket to go to orbit. It had six SRBS attached by radial separators, all in the same stage. When I launched it and tried to detach the boosters, only one detached, then the next with the next press of space, and so on. This resulted in a crash.
Why is this? Is there some tweakable I'm missing?
-
Is it possible at all to have a celestial object with a positive or negative charge?
Yeah, you just have to rub a balloon against it really fast.
-
Wherever it likes. It can't be detected, so it could be anywhere.

Everybody that I've seen in this thread seems either to be advocating cannons powered by explosives, or lasers. Neither of these is particularly practical compared to a rail/coilgun:
- Cannons release clouds of hot gas from the muzzle,which is basically a big "I'm right here, shoot me" sign for the enemy. Not to mention the fact that cannon shells carry their propulsion with them, and are therefore heavier.
- Lasers(at least ones with a high enough energy to cause damage) require truly huge amounts of electricity, which makes your ship a bigger target. Not to mention that , unlike kinetic weapons which can keep going(theoretically) forever, a laser actually has a limited range!
As for powering the railgun, a super capacitor could provide power storage, as it is unlikely such a weapon would need to fire continuously.​
A microwave based directed energy weapon might also work, though with the same drawbacks as a laser.

The figures load MARS-3 onto some sort of sledge, and they are dragged off.
Sorry for the bad Russian, I used Google Translate.

You jelly?
it is ok, i do have legs really

Not allowed. Players may not have a score over 100. If a player violates this rule, his score is reduced to 0.
I grant myself 1 point for correcting this erroneous assumption.

The opposite of your statement would be "No non-squares are not non-rectangles", which is true.
No it isn't. via negation, that statement is equivalent to "No non-squares are rectangles".
No dyson spheres in local galaxies

The only reason to build a Dyson sphere would be to harness it for usable land area-stars are by no means the most efficient way of converting hydrogen into energy(even less so than fusion in a magnetically-confined reactor, due to the vast majority of gas being in the unused outer layers).
It would still be a good symbol of cultural and economic dominance though, just like the Great Wall of China
