Now stop trying to fire a laser through the Earths atmosphere and see what happens. Firing lasers at the moon from Earth means it runs into a couple hundred thousand miles of various gases before it reaches space... You don't have that problem in space.
Landed probes on asteroids? No, not once. We have crashed things into them and tremendous rates of speed causing what probably resulted in some nuclear fusion on the surface anyway.
The best we've gotten is intentionally crashing into them at 23kilo/kph
Its going to have the exact same force it gave to you in the first place, 100% canceling itself out. Do you think in space energy that comes from humans is magically different from energy that interact with the asteroid?
Perhaps you should consider going back to school.
Equal and opposite reactions... basic physics here.
Its cute how you seem to think the energy imparted is some how magically different because it doesn't touch.
You can not be more efficient than direct contact pushing, anything else is less efficient. It may not be possible to push directly on the surface of the asteroid for any number of reasons however.
The reason you can only use a bit of fuel over a long period of time is because you're not exerting any useful amount of force on the object.
The problem is that your nuke would fire bits off in every direction and that would balance out.
Then you've got shitty aim.
You detonate near the surface on one side. You loose a large portion of energy to empty space, but the energy that is applied is all applied in the same general direction.
If we could 'just steer the asteroid into Jupiter' we'd already have solved this problem wouldn't we? We are, in fact, talking about ways to 'steer' the asteroid.
Just solve your problem with the solution to your problem the the solution solves.
You do realize that to 'pull it with gravity' requires AT LEAST the same amount of fuel as direct contact. It is less efficient so it will require MORE fuel on that alone. To go on top of that, since if you just pointed your rocket straight against the gravity, you would be thrusting against the asteroid, essentially your own fuel would be canceling its own force out by pulling on itself, so you have to aim your thrust slightly to the side, and counter balance that rocket with another one pushing in a way to counteract the lateral motion. This means you now have more waste as you're spending fuel balancing the lateral forces.
In order for this 'gravity tether' rocket to have enough time to pull the asteroid's course enough to make a difference, it would be far more effective to break it up into tiiny peice and let the debris spread out over the next 50 years it takes to reach Earth.
The problem with the gravity tether is the time required to exert any sizable amount of force on it, with that sort of forewarning, blowing it up becomes logical. The debris will spread out and have its course effected by the rest of the solar system in new ways. Sure, we'll still get SOME bits, but not all.
You'd need decades of time for a gravity tether to do even a noticeable change, forget useful.
Which is better: Getting hit by Mt Everast or a Volvo?
Which is better: Half of Mt Everast burning up in the atmosphere because most of it is broken down into the size of a Volvo or the whole thing hitting the planet because someone forgot that the gravity tether's retro rockets... are thrusting AGAINST THE OBJECT TRYING TO BE MOVED EFFECTIVELY CANCELING ITS OWN FORCE OUT.
Depending on which version you read. There isn't a single definitive version of the HHGTTG, I have at least 3 different versions on my bookshelf at home.
Because Linux distros typically don't phone home at any point during installation or operation,
Bullshit excuse. They do request updates, don't they? Its not hard to tell who's using your Linux distro when they come to you for patches.
If a company with 1000 seats downloads Ubuntu once and uses that single download to install it on all 1000 PCs, while the business next door has all ten of its users download Mint to install on their own desktops then Mint appears to be ten times as popular as Ubuntu.
Yes, if you picked a particular 5 millisecond period and just used that as a basis for all of your extrapolation, but when you look at it on average, that sort of thing doesn't matter.
Of course, that is assuming that oil is indeed a plant byproduct and not something entirely unrelated that we're confused about, which is a distinct possibility.
Other than 'we found bits of decayed plant matter in it' there really is nothing that indicates oil comes from living organisms.
Or just live in a state that doesn't suck. Plenty of states require NO reason to terminate an employee, and 'I don't like you' is a valid reason EVERYWHERE believe it or not. 'Doesn't work well with the team' is perfectly acceptable.
The only way anything else happens is if someone presents a judge with clear evidence of systemic prejudice in some form.
Wow, there isn't a single true part of that entire post, it's one of the most ignorant things I've seen on slashdot that wasn't a flat out obvious troll. Thats impressive.
As is always the case with stupid headlines asking a question.
One could also argue that it doesnt' work at Valve either considering how long people have been waiting for the next half life episode.
In reality however, I'd bet a months pay Valve has a clear hierarchy of people who just control the situation even though its not written on some org chart somewhere. Dominant personality will create leadership hierarchies naturally without any outside influence.
And lets just common sense. Gabe is beyond any doubt, 'the boss' and it trickles down from there probably loosely related to time at the company.
Pretending its Anarchy and everything 'just gets done' because everyone knows the parts that need to be done is just for those too stupid to recognize whats going on.
Best part is how the self-entitled morons that think this is a great idea how modded down every comment that points out how much bullshit of a statement the headline and summary are. Just because you can mod down on slashdot doesn't make it true.
Other the the word 'judge', what the fuck does the headline have to do with the summary? Is slashdot trying to get some sort of record for worst 'journalism' ever?

That would be 'push', wouldn't it?
Now take the Earth's atmosphere out of the way and how much does it disperse? You're missing a good bit of the fundamentals of how lasers work.
Just put the gun in your mouth and pull the trigger please, you're wasting resources that could be used on someone useful.
Yes, I want you to wipe out everything in orbit if my only other option is to not be around tomorrow to use it.
What kind of idiot are you?

Tyson killed Pluto damnit! He's evil!
(Note: I could care less that he got Pluto demoted, just making a bad joke)
You sir, are a racist fuck.
You know nothing about the AC, you assume he/she is a racist just because they are saying something to disagree with a black man.
You're projecting your own ignorance and racism on others and its as obvious as it gets.
Crawl back in your hole and keep your fake liberal posture put away so it doesn't make it so obvious you're a tool.
How exactly are you calculating gravitation force without any separation distances?
You do realize that to 'pull it with gravity' requires AT LEAST the same amount of fuel as direct contact. It is less efficient so it will require MORE fuel on that alone. To go on top of that, since if you just pointed your rocket straight against the gravity, you would be thrusting against the asteroid, essentially your own fuel would be canceling its own force out by pulling on itself, so you have to aim your thrust slightly to the side, and counter balance that rocket with another one pushing in a way to counteract the lateral motion.

I'm not sure where you got Mike from? The only relation I see is that Mike is black ... but so is Neil so I don't get the insightful mod?

You're seriously calling Douglas Adams a bad writer?

Yes, I'm aware of the limitations imposed by Newton
Newton is not a god. He imposes no laws. He learned of the laws of the universe, he didn't create physics.
