    This is exactly why Star Trek ships had "deflector shields". As a bonus, they look much nicer than big blocks of ice when you're doing a camera shot of the outside of the spacecraft.

    You'd have to use magnetic confinement. Of course, that itself would require a constant power source, or else BOOM.

    If you don't need to carry propellant, not only can you get to Pluto in 18 months, you could probably decelerate and get into orbit. This could make for some exciting exploration of our solar system. And maybe we can catch/pass Voyager with a new interstellar probe?

    It doesn't mean that at all, not necessarily. This drive still needs electrical power to operate, so it needs an energy source. Theoretically, assuming they can make a version that actually produces a decent amount of thrust, you could have solar-powered probes exploring the inner solar system using this drive. However, Pluto is too far away, and there simply isn't enough available energy there from sunlight. There's a reason deep-space probes use RTGs instead of solar panels: once you get past Mars or Jupiter, there just isn't enough light for them to be worthwhile.

    If linear momentum is not conserved, the laws of physics are not the same throughout the universe and vice-versa.

    Not necessarily; it could be like Newton's Laws vis-à-vis relativity. Newton's Laws model behavior just fine at low speeds (like an apple falling from a tree), but don't hold up at velocities closer to lightspeed (like space probes traveling to Pluto).

    This thing could just be taking advantage of some unknown branch of physics, something we just don't normally see. Before space travel, humans never made anything which moved faster than a bullet (a little over the speed of sound), so we never had much of an opportunity to see that Newton's Laws were incomplete.

    As for Germany, while they do have some great engineering over there, don't forget that homeopathy is also popular there and I believe was started there.

    Of course, we Americans aren't any better, and quite a bit worse in many ways: not only do we use a lot of homeopathy, we also believe vaccines cause autism, and we buy into a lot of other pseudoscientific BS like crystal healing. We also started not one, but two wacko religions within the last 200 years (Scientology--Xenu of the Galactic Confederation brought people here in DC9s and killed them with an a-bomb and their disembodied souls are the cause of all our mental problems; and Mormonism--an angel showed Joseph Smith where to find some golden plates and a "seer stone" to read them with, which document Jesus coming to ancient Mesoamerica in contradiction of all archeological evidence, so he could start a new religion that allowed him to have multiple wives. And oh yeah, if you're a good Mormon, after you die, you'll become god over another planet).

    When are you disciples of the religion of atheism going to admit you and the fundies are looking at opposite sides of the same coin? You're both passionate, and you're both intolerant and outspoken. Only difference is you both believe you're correct in different ways.

    That depends on your definition of "atheism". The word literally means "without religion" (a + theism), so it can both be applied to people who passionately don't believe in theology, and people who simply don't know and don't adhere to any religion.

    Of course, we tend to call the latter "agnostics" these days, but many of them also call themselves "atheists".

    Did they direct the Engineers to design faulty suspension?

    Management is *always* at fault, any time there's a problem. That's why they're called "management"; if they can't properly manage, they should get another job, like janitorial work. Engineers are employees, and just do what they're told, under threat of losing their job. So yes, management did direct the engineers to design a faulty suspension, one way or another, either by demanding that it be cheap, that it be done too quickly, that important analysis steps be skipped in the interest of time and cost, that safety testing not be done because of time and cost, etc.

    The final quality of the product is up to management, whether it's suspension safety or wireless security. It's their job to make sure the engineering is done properly, and if they're not competent to judge that (and their employees aren't either), it's their job to hire consultants to help them with it.

    It's only enforceable because it isn't email.

    All this stupid thing is, is a system where the recipient gets a link to click on, which lets them go view the "email" (message) on some server somewhere, subject to a bunch of restrictions. I think there's also a browser plugin that basically does the same thing, but making it appear more like you're reading an email instead of just being redirected to some server.

    This isn't email in the traditional SMTP sense.

    Android - Huge app ecosystem, but a non-starter for anyone who doesn't consider it acceptable for mass scale harvesting of personal data by an advertising company. It's a "half open" platform, but the app ecosystem is a clusterfuck of crapware.

    The crapware really isn't a problem. No one is forcing you to install crapware on your phone from the app store (undeletable crapware pre-loaded by the carrier and mfgr is another matter). If you're picky about what apps you install, you shouldn't have a problem. It's really no different from Windows that way: there's all kinds of crapware out there, but no one is forcing you to install, say, McAfee or PeopleSoft or some random toolbar on your Windows PC. Just stick to Firefox and MS or LibreOffice and you'll be fine. Now the danger of platforms like this is that you can easily install crapware, and you have to be a bit savvy and not completely naive and trusting that everything out there is OK. With (relative) freedom comes responsibility. So if you're a gullible fool, then you better stick with iOS and Apple iDevices, so that Apple can hold your hand and make sure you don't do anything you're not supposed to.

    Unfortunately, you're right about the mass harvesting of personal data part. This (and Apple's approach too) is a consequence of having a non-open platform, where you don't have access to the source code, nor can you easily change the software. Whoever controls the platform can do whatever they want with it. With Google, they mass-harvest personal data. With Apple, they control everything you do. With MS, they give you a shitty, broken UI.

You can't just say "well make the prisons nice like the ones in my country!"; that's like telling a dumb person who failed his algebra test to just get smart and ace it like you did. Or telling a country with severe economic problems to just become a utopian society where there's no money, like on Star Trek.

    But we know from historical contexts that prison is better than the alternative of wholesale punitive murder.

    We know that how? You still haven't proven that it's better to be tortured in a squalid prison cell and be subject to constant rape, for decades, than it is to be quickly (and presumably not too painfully) executed.
