There's a difference between reinventing the wheel, and building one yourself so that you know how it works. Students should learn to write their own code before they learn to reuse other people's code.
Yes! They did take a car! Try walking any reasonable distance in a spacesuit, 1/6 gravity or not. You'll see why they had good reason to bring a vehicle with them. It's not like they brought a chevy nova with them either. It wasn't much more than seats, wheels, and a motor. Why is it so hard to believe? We are just building a space station now, does that mean the ones that were up 20 years ago didn't exist? I mean, if it's so damn expensive that we keep having to cut the budget for it, how could they ever have done it back then!
The temperature below the surface is almost definitly NOT -200, nor does it wildly fluctuate. It is most likely heated from below by geothermal energy generated by tidal forces, and protected from radiation from above by the layer of surface ice.
I'm sick of this "We never went to the moon" bullshit. Every arguement for the moon landings being fake can be easily debunked by anyone with half a clue. Until someone shows real evidence that we haven't been there, unlike the real evidence that we HAVE, then shut up already.
Actually Jupiter isn't a brown dwarf. In a brown dwarf, there is enough mass for deuterium fusion to occur, which doesn't happen until around 12 times Jupiter's mass if I remember right. Jupiter is just a gas giant.
That first point is stupid, you don't need a pill, just a rock.
Second, who cares about mice. Mice make excelent testers for drugs, and food for snakes. Other than that who cares.
The third point you have makes the first two even worse.. If you think crackheads or mice are more inportant than people with real problems that can benefit from the drugs, then you should be the one that they test the drugs on.
It's called Hawking radiation, it occurs when spontaneous pair generation occurs right next to the event horizon and one of the particles falls in while the other escapes.
Yes but if you accept the fact (fairly well proven) that all matter warps space, then black holes aren't all that strange anymore. If everything warps, space, then it becomes fairly obvious that something dense enough will warp it to the point that it's inescapable.
First of all, wouldn't it be easier to send an actual nuke than a particle accelerator? Do you have any idea how big they are?
Secondly, the amount of antimatter generated by a particle accelerator would NOT be equivilant to a large nuke, it would at most slightly warm up a spot on the asteroid. To equal a large nuke, you would need to hit the asteroid with a kilogram of antimatter at least, not the nanograms that particle accelerators put out.
The only way I see this having anything to do with colonizing the galaxy, it that if you turn the laser away from earth you can use it to give a solar sail a nice power boost.
Why would they change, that would mean rewriting their entire codebase. And what does linux have to do with Real support? They would not be including realplayer or anything, just the codecs. And the codecs woud not need to be open source to do this. Even TiVo's own software isn't open source.
They're also selling software updates. Ask anyone who's had a tivo long enough to have run multiple versions of the software, the upgrades always add nice new features.
No, there couldn't store an infinite amount of energy in it. It "stores" the light in the energy states of the electrons in the crystal. Put in to much energy and you'll just end up ionizing the atoms and probably breaking down the structure of the crystal.
The big deal is that this is the first time they've directly observed something this size orbiting so far from a star, it challanges the theories of solar system formation. I may be wrong, but I don't think we've observed (directly or indirectly) anything close planet sized that is more than a few AU from it's parent star.
I know it's not a perfect analogy, but it's not comletely wrong. You have to imagine not a normal shotgun, but one that fires buckshot at rifle velocities. Breaking up an asteroid isn't going to slow it down.
The effects aren't the same, but they are both very very bad. First of all, how many nuclear blasts would it take to break up a large asteroid into small enough pieces that they would burn up? Is it even possible? And if so, how many millions of tons of irradiated rock would be dumped into that atmosphere when it hit?
It's most likely not even possible to break up a large asteroid into pieces small enough that they would burn up. Say you have a 300m x 300m x 300m asteroid (squared to save me from getting a calculator). Hit it hard enough to break it into 30m x 30m x 30m pieces and you've got 1000 asteroids hitting a much wider area than the single impact would have.
I haven't done the math, but I think there are only 2 possible lunar stationary orbits. One isn't really an orbit, it's the spot directly between the earth and the moon where the net gravity is zero. The other is on the far side of the moon, directly in line with the earth and moon. I'm not going to work out the altitude of either of these but it should be trivial to do.
Well the first 3 points on your list still require binaries being copied between systems and run as root. The last no longer fits the definition of a virus, that would be a worm.

My point was just that people have been using zip for years before windows had any support for it.
How long has windows had built in support for zip files?

You're right, but I think that part is fairly obvious. ;)

A brown dwarf is a star massive enough for deuterium fusion, but not massive enough for normal hydrogen to fuse.

Find a rifle, shoot yourself in the foot. Then find a shotgun and do the same. Which was worse?
No, a near miss, as in it missed, but it was damn close.
Actually the mass of a satellite is irrelevant in regards to its orbital radius.

Thanks for explaining that to him, saved me alot of typing. :)
