They travel towards it on a trajectory that takes them close to, but not lethally close to, the black hole. They gain so much velocity that they continue out never to return again.
Close, but no cigar.
You need three bodies to interact : a massive central body ("primary") and two "light" (relatively small, but not zero mass) "secondary" objects. All three orbit around their mutual barycentre ("centre of gravity", but it moves as the positions of the three objects change in relation to each other) and the two lighter particles are generally approaching the primary rapidly, while closely orbiting each other. Near peri-primary, one of the secondaries is captured by the primary, but transfers it's momentum to the other secondary. This gives the remaining secondary a velocity which can exceed the escape velocity of the original system.
That's a non-mathematical description ; you really need to do the maths. There are software simulators for gravitating systems that can demonstrate this, but TBH I've not looked for one since I got rid of my Win3.11 system.
If they did try to enforce the copyright, the first thing violators would probably know about it is waking up with their head (only) in their horse's bed.
Then the process of publicly making the pirate's friends, family and home city regret his actions would start. Very regret, and very public.
We know that because the last time the magma chamber was unroofed, some 650,000 years ago, a layer of ash can be correlated all the way to the east coast.
Sorry, but the wind was from the N during that event. Significant ashfall didn't extend east of the Missssssssss (the N-S one of USA's two big rivers ; I've forgotten which is which). There may well be millimetres of ash in lake deposits etc further E from there, but that's not the same as "significant".
Yellowstone super volcano is a planetary killer - or best scenario: many, many, many years of the equivalent of nuclear winter.
Wearing my geologist's hard hat (tricky, since it's in my locker on the drilling rig, 7000km away), Yellowstone is likely to be pretty bad when it goes of (not "when", not "if"), but it's barely a nuclear winter (almost certainly not for the southern half of the planet), and not a planetary killer for anything not restricted to the North American continent.
A mild degree of concern is appropriate ; hysteria isn't.
TFA says this was in the section of the city that was "non-elite."
Probably more to the point is that Pompeii itself was a fairly nondescript little town in a minor province. It's like finding giraffe on the menu in a diner in Peroria (or wherever it is where you should "see how it plays in P......").
Well, a couple cities anyway. I still blame bad city planning. Herculanium, as well.
While not defending "not listening to the Earth" in general, at the time there had been no significant volcanic activity in and around Vesuvius for some tens of generations, if not longer. There was no mental image of associating fumaroles and intermittent earthquakes with volcanic activity. Maybe in Indonesia or East Africa, where such things happened more frequently, there are more grounds for criticism, but here I can't really blame the Latins (Samnites, whoever were the local tribe at the time) for ignorance at the time.
At least, I can't blame them any more than the current authorities for continuing to build Naples (sandwiched between Vesuvius and the Campi Fhlegere eruption centre), or Rome (expanding into the Monte Albano eruption centre). Or San Francisco, Los Angeles, Seattle and Tokyo for that matter.
I get contacted on linkedin a few times a month by recruiters.
Same here. Every one of them gets reported as a spammer, on the grounds that they've clearly not read my CV, and in particular the part that says "I'm not looking for a new job, and anyone approaching me to offer me one will be treated as a spammer".
I've no way of knowing how many "genuine" head hunters there are out there ; nor have I particularly any interest in finding out, as I can't figure out how the information could be of use or interest to me. But there are lots of spammers on Linked-In.
I've never understood that particular piece of American insanity. Homeowner's Associations, that is. I've never heard of such a thing in British housing at all, and I'm not sure that it would be in the least bit legally enforceable, at least for detached / semi-detached dwellings on freehold. I can see some reasons for restrictions on what you can do to a property in a terrace, or in an apartment block, but as long as you've got the freehold, I'm not sure that there is anything that a "homeowner's association" can do to enforce their regulations on someone who moves into an area. And indeed, I'm not in the least bit sure that any such alleged regulations could be compelled onto a second purchaser. I certainly wouldn't accept any such restrictions on a property that I was going to buy (not that I see any reason to move, unless we leave Europe).
I think that the point is that the developers can have what they want, but after putting the program through it's acceptance and validation tests, the useful (to a reenigne) error descriptions should be stripped out. Really out. It should NOT be left in place for the public-facing code.
Welcome back to the world stage, China. Please don't go all Genghis on us like last time.
You do know that Genghis Khan (however you want to transliterate it) wasn't actually Chinese, don't you? And to be honest, he wasn't particularly expansionist - once he had conquered the Chinese, he pretty much stopped at the pre-existing borders. He had enough on his plate massacring enough of the pre-existing apparatus of state to ensure the compliance of the remainder.
I don't know about your country, but in mine the mountain and cave rescue is done by... mountaineers and cavers. Who also render considerable assistance to the police when they need personnel. (The recent jubilee of the Lockerbie bombing, for example, reminded me of the cave and mountain rescue teams of the whole of northern England and southern Scotland accumulating thousands of man-days searching for evidence, often in really miserable weather conditions - as many man days as the police could put in themselves.)
There are several reasons for this : to acquire the necessary skills to perform the rescue, you need to be [DOH!] a mountaineer or caver of many years experience ; you can't compel employees to perform this sort of work, often at real risk to their lives (even if their reluctant compliance would be any good at all) ; and in the social milieu of mountaineering and/ or caving, to be the target of an avoidable or unnecessary call-out is really, really embarrassing. Not least because the people who rescue you are likely to be friends or acquaintances.
Other than that - you do get random people caught up in such events. The tourist who slips on a footpath and falls into a river to be swept away. The farmer's sheep which falls down a hole in the ground (there's an annual spate of practice sessions recovering lambs). The car that crashes on a remote stretch of public road. And most importantly (in our context) the plane on a military training flight which goes into a mountain side and needs both the crew and (sensitive) equipment recovered.
That last case is why the Air Force maintain their own mountain rescue service, and they acknowledge that if they were prevented from assisting the civilian mountain rescue teams, then their costs for training and personnel would actually increase. Because they would have to spend more time with more staff dedicated to sitting around waiting for something to happen, and/ or drilling, and they wouldn't be able to call in the civilians for support when something big does go down. Case in point was last winter with two separate parties of special forces on training missions getting caught in the same storm in different areas, where it was the civilians who went in and located the missing persons because the weather was too bad for helicopters.
When ever I hear people saying the sort of thing that you say, I think to myself "there is someone who knows absolutely fuck-all about what he is talking about, and is the more dangerous for it."
Reading TFA (yeah, I know ; not the way it's done this decade.), it's significantly different to what TFS says:
The prescription lenses will be available in an array of styles and colors that clip onto Glass and cost as low as US$99
To be honest, that sounds rather like the "clip on" sunglass covers that you've been able to get for 40+ years that I can remember. Which would also mean that they're almost certainly single vision (probably almost useless for you, given the way that you describe your vision), made of moulded or cast plastic (useless for me - I have to remove and replace my glasses multiple times per minute when I'm in the lab, switching between the microscope and the hand specimens ; and there's a lot of grit in that environment, which destroys even "hard coated" plastic lenses in a matter of hours), and will look like shit and fall off at the slightest opportunity (useless for almost anyone).
When I got a single-vision prescription SCUBA diving mask made (under a month before getting prescribed for bifocals! Typical!), it was about £100 for the two prescription ground surfaces in glass, plus another £75 for the mask body (comparable to the plain glass version's street price ; good quality mask) ; that's something like USD 70 per prescription grinding. So I'd guess you're getting triple-vision lenses, or double-vision with an astigmatic correction?
What do you do for safety spectacles at your worksites?
(3) or the "bipedal and hexapedal animals only" rule
(4) given 3, what about the starfish? will nobody think of the strip-club-attending starfish?
(5) given any and all of the above, I think the answer is "yes". Regardless of whether "state" refers to a trivial local administration level, or a sovereign nation with it's own languages, army, borders and diplomatic recognition.
But I'm also in favor of the hunters destroying PETA's drones,
But that would require the hunters to be competent marksmen with their weaponry of choice (slingshot, spear+atlatl, bow and arrow, even explosively-propelled projectile launchers if that's legal for amateurs in your country). And THAT is discrimination between the competent and the incompetent, which is also not allowed!
Stop being insulting to rocks. I study them more closely than most people and I understand their vivid and distinct characters and behaviours better than most people do. They'd be deeply upset to be compared to these "customs officers", whose customs seem to be those of boorish thuggish humans, not like restrained thoughtful rocks.
When was the last time that you met a rock that would take this sort of action without thinking about it for a millennium or several?

You need a "statistics grammar" filter before posting. I can work out what you probably mean, but what you've typed is incoherent.
For a sun-like star, that's around a diameter per hour.
Hardly speedy.
Well, for some of you on whichever side of whichever Pond you're on.

Only true for the almost insignificant portion of the history of the planet covered by human habitation AND record keeping.
For "big", and "human history" (but not "written records"), try Toba : around 100x Krakatoa, at about 73000 ago.

Errr, have you paid any attention to what formed Mauritius?

The Roman approach to height enhancement for males was to cut the other males off at the knee.
Subtlety was never their strong point.
There are important differences between these?

Hold fire on that for a few months, boy! The concentration camps and gas chambers are still under construction.
