    I think the interesting question is, what would constitute evidence of the Oort cloud's actual existence?

    Well, how about the range of aphelion distances of the orbits of sporadic comets? OK, it's exactly the evidence that Oort used back in ... when was it, about 1940? ... but that doesn't stop it from being true. As far as it goes. (We've also acquired a lot more orbital data on Kuiper belt objects, and done a huge amount of modelling of how you can put things there, from here or here, without also putting things into what fit's Oort's description.

    Yes. And? The nuclear reactions inside a detonating hydrogen bomb are theoretical constructs too. You are within 40km of a theoretical construct which it is quite unlikely that anyone is ever going to see without landing a 5km+ meteorite into the Earth at an orbital velocity. what is going on inside your head while you read and think are more disputed theoretical concepts then the Oort cloud.

    But, the fact that things are stacked in the house's favor and that the house keeps it that way is dubious ethically speaking.

    How is it dubious ethically speaking? The rules are designed to give the house an edge ; no house would allow play under rules that did not guarantee them an edge ("edge" can simply be room, croupier and food fees).

    perhaps it was a bad example to refer to "The Hubble Telescope" as it is indeed designed to look deep at a very small segment of the sky.

    Actually, not particularly ; it's a deliberately middle-of-the-road telescope design, because of the changeable cameras. For PHA-hunting,the pixel size matters. If you've got a very faint object, and you focus it perfectly (well, Rayleigh criterion ; no, you "cannae change the Laws of Physics" in the real world, no matter how Canadian your Aberdonian accent is.) onto a sensor with large pixels (relatively low resolution), then your signal may be lost in the thermal and optical noise. Did I mention Zodiacal light and things like that? Since most of the "interesting" objects are going to be in (near) the plane of the ecliptic, you're in competition with this as well as "deep sky" background levels of light.

    Hubble's different cameras are optimised for different tasks - some have been as light buckets, some for near IR, some for high resolution, some for spectroscopy. Horses for courses. But all are subject to nearly the same geometrical constraints of the prime mirror and optical front end (including the "Ooops!" package of corrective optics). You could maybe get a factor of ten by efficiency of telescope design. But the observing task is in the order of five orders of magnitude more than a Hubble-grade telescope could handle. There are probably useful things you could do with more Hubble-grade instruments - rapid follow up and detailed analysis of PHAs discovered by the survey system is already a task that it gets used for. But it's not a wide-field survey system. For that, you need a very different telescope design. Possibly a radically different design ... I'm thinking of perhaps a 1-d telescope (and internally I'm wincing at the memory of David Levy's "Fork Mounted Telescope" design, NOT pictured at http://books.google.co.uk/books?id=sEyCQEqLAnIC&lpg=PA208&ots=ytsNGPV1wa&dq=Levy%20fork%20mounted%20telescope&pg=PA208#v=onepage&q=Levy%20fork%20mounted%20telescope&f=false, ) in a Earth-Trojan orbit, and completing an ecliptic scan every couple of days in it's orbit. Hmmm, two ; one Greek, one Trojan ; a more conventional co-mounted imaging telescope to provide reference imagery to help the 1-d light bucket (light ribbon?) sensor be interpreted. That might work. For the ecliptic. Actually, if the idea of using 1-d sensors works, that could take several orders of magnitude out of the surveying task. That was a worthwhile bit of brain-sweat.

    On the other hand, if we get hit by a "planet killer", I guess some cockroach will survive ;D

    I rather suspect that the moon-forming Giant Impact wouldn't have left the cockroaches staggering around wondering what hit them ; equally, I suspect that the cockroaches didn't notice the "dinosaur killer" (didn't I see mention of a new paper by Gerta "Chixulub was Innocent!" Keller recently .... I'd better follow that up.). But I'm less bothered about the existence of cockroaches than I am about the existence of self-aware self-conscious organisms with imaginations. Life may not be so difficult to get started (though we're still working on a sample of 1 to determine exactly how that happened, if we ever can) ; but there have been lots of contingent events in the history of life where there's no obvious reason for history to have gone "our way" rather than "another way". Was there anything inevitable about the rise of grasses 20-odd million years ago which currently provide 70-80% of our calories?

    When I worked one summer as a Resident Adviser, I had one guest that constantly complained about noise from me. Thing was, I got up to go to work at 4am to avoid traffic (I had to drive 40 miles each way through downtown Chicago). Mind you, I had the TV volume for news, at that hour, just loud enough I could hear it when I was in my room

    I know the feeling.

    Until recently we were living in an apartment where the occupant upstairs was dealing crack. We also suspect that he was a grass for the police, so he avoided getting busted. As his use (and sales) escalated, the music from his rooms through our ceilings got worse and worse. So we started the process of getting the council's Noise Complaints people onto him, which steadily worked. His business did not benefit from the disruption of having the police hammering on his door in front of his customers at 03:00, scaring them ; he didn't like being told that because of the noise, the police could now forcibly enter his premises at any time to seize his sound equipment if it was making too much noise (and his police contacts could do nothing to protect him from this ... it went through a different branch of the police) ... all lots of hassle. (Spreading the suspicion of him being a grass probably didn't hurt either.)

    But explicitly what the council could not entertain complaints about were "normal" sounds - the squeeking of floor boards, normal conversation, normal TV - they were not something you could (successfully) complain about, even if they disturbed you. When the buildings were built for the council in the 1930s the design didn't consider sound insulation to be an issue, so you just had to live with it. And will have to until they get a major refit involving new structural woodwork). Which will be 100 to 200 years, looking at ground stability and weatherproofing.

    Why can't you cover your walls in foam? Go to the big box store and get 2-3" blue or pink plastic insulation and just put it up. Use double sided tape. No one says you have to tail things to the wall.

    Other people have pointed out that some foams can be lethally flammable, which is true.

    But when I lived in university-provided accommodation (I guess that's what the Americanism "dorm" means), the rules about what you could use to attach things to the wall were unambiguous. You could use "Blu-Tak", or "White-Tak". Nothing else. Absolutely nothing else. And the cleaning staff were under orders to report anyone using anything else, and were also under orders (on pain of disciplinary action up to and including being fired) to report any rooms which they can't get into for two consecutive weeks. It can take weeks to clean up form a corpse, and costs a lot of money.
    These accommodations aren't democracies, and there are no human rights issues involved- if you don't like the rules which you sign up to before you get your key, you're free to go somewhere else and pay them, not the university. And the rules aren't intended to stifle your personal creativity. They're intended to protect the building's decor from damage, so that when you move out, the room can be re-let in a usable condition in a matter of days.
    If you went into a hotel room and stuck foam all over the walls, you'd expect a large repair bill. Same here.

    If the university is providing these "dorms", they'll have rules about reasonable behaviour. And they'll have complaints procedures. Use them. And if you get shit through your letter box, report that. And if you get shot in the head, "Welcome to America, home of the Brave." That'll deal with the "bong hitters" (whatever that is. Sorry, I was a spliff man myself ; much quieter and cooler) and music players. Can't do much about reasonable conversation, shagging, vomiting etc. though. But consider it a life lesson : for most of your life you're going to have to live with people whose number one occupation is not "making your life easy".

    I do appreciate where the OP is coming from ; I'm the reverse : silence worries me. But I live in the city ; when I'm at work, the noise of the engines, cranes, passing helicopters and the occasional 20m wave hitting the boat all create ambient noise ; when I'm holidaying in the wilds, the wind soughs through the trees and flaps the tent. Silence is rare. It usually means that something has gone (badly) wrong.

    Anyway, regarding off planet telescopes, what we need is basically 2 of them (more is better) and shoot them into an orbit perpendicular to the ecliptic. So basically they circle the sun more or less with the same distance than the earth. But half a year above the plane and half a year below the plane. The effect of this is: the sun is only blocking a part of the view field two times a year. With two such telescopes in 30 degree "distance" behind each other we always had a view from top or from bottom onto the solar system.

    OK ; so your scopes would then, during the northern and southern (what's the word ... "apparition"?) of each orbit, they'd need to schedule [calculates] around 2000 square degrees of sky [I know, I should be working in steradians, but it's 23:00 local and I'm up at 05:00 for work at 05:30.
