    It's been a while, and I'm too lazy to fully read Wikipedia, but I want to say from the decomposition of neutrons. Neutron decay = 1 electron, 1 proton, & 1 neutrino.
    Though I may be wrong.

    Wait, checked it. Close, the above is Beta negative decay, so it emits an anti-neutrino. So, you want Beta positive for a regular (electron) neutrino.

    *shrugs* It may be possible to travel faster than light. However, we do tend to have a good idea how fast various known particles DO travel. There may be unknown particles that do travel faster than light, and / or other methods that allow normal matter to traverse space / time much faster than what is currently considered feasible.

    However, CERN wasn't, to our knowledge, using wormholes or exotic matter or what not that particular day (Thursdays are wormhole days, Fridays are black-hole days, Saturdays are the day that they perform tune-ups on the chips they implanted in the EU politicians' brains, Sundays are tapioca pudding days), so no one is taking the experimental results too seriously.

    No one is debating that. The original press release said that they were checking results elsewhere to ensure that they were correct. Broken / miscalibrated equipment is the bane of every scientist, and with-holding of results until after several of your friends confirm things is always a good idea (it helps prevent publications of perpetual motion machines and what not).

    While not belittling CERN's accomplishments nor their professionalism, it is a little annoying to let the press pump out another headline talking about 'hope' while they are still dealing with potential errors in their experimental setup. It ranks up there with the "New Cures for AIDS" postings on r/Science, where a new cure is apparently found every week -> it becomes tabloid material.

    The standard protocol remains the same -> fix the broken equipment, run the experiment, check results, run the experiment again, check the results again, call some of your friends somewhere else & have them run the experiment a few times, compare results, call another friend, run the experiment again, compare results...and so on, at least a dozen or so times...then, very cautiously, inform the scientific community that you are intending to put out a paper regarding said results, and have your editor & interested parties review an advance copy to try and find any errors, then publish & batten down the hatches. The general idea being that someone, somewhere will have properly functioning equipment, and they will spot the error before removing it (at a later time) becomes a political problem. Once it makes it into the science textbooks, it becomes almost impossible to remove, and what more, a lot of people will be operating with the incorrect information.

    So, CERN should fix the equipment (upgrade if they can), check their results, do the rest of the above, then call in the reporters to state whether or not we need to worry about rewriting the known laws of physics.

    The open assumption is that the data put on Facebook is entirely valid. Since it cannot be held to be valid, it becomes NP-Hard to sort through all the data for the bits which are true and the bits which are false.

    It's entirely possible to setup an identity for someone who doesn't exist (trolls + marketers do this all the time); that's one strike against the data. It's also possible to have a user simply lie, such as saying they were at a party or visiting a cousin when they weren't. Job applicants could maintain an entire account simply for the purposes of appearing social while maintaining a carefully controlled, carefully tailored public image. Finally, other people may post things, or even borrow someone's account, and change the user's profile to something unsavory, as a prank.

    Anyone who puts stock in this data as some sort of glimpse into another's thinking should not be allowed to make any kind of lasting decision.

    Indeed. However, the general thought is that although the [Insert Foreign Power] can tacitly back one of their chosen industries, to do so they must pull resources from somewhere else, which creates an opening.

    Think of the marketplace as a battlefield. To put 5 more tanks on the lines protecting [Insert Politically-Favored Company], they must draw 5 tanks away from [Insert Some Other Company Not Held In As High Regard]. They strengthen one, at the cost of another; by focusing on their front lines, they've left their flanks unguarded. When the imbalance becomes large enough, competition from within and without begins appearing in earnest, destroying what's left of those weakened companies, and coming up from behind on those previously favored companies.

    To protect GM, the United States had to ultimately sacrifice a fair number of less-favored, weaker, and / or newly created companies. Ultimately, it's a form of cannibalization, where Saturn eats his sons to maintain his power (to mix in some Roman mythology here, just for fun).

    This is why protectionist economies eventually fail -> the market moves at light-speed or faster, cannot be bribed, and is constantly checking for weaknesses; the people working the protectionist racket move at human speeds, can be bribed, and are not always aware of weaknesses in either themselves, their friends, or their enemies. As the effects of poor decisions take some time to ripple throughout the markets (the effects thereof, not the decisions themselves), endlessly cascading until they hit a particular resonance (at which point destruction, creative or otherwise appears), things such as high tariffs may take several years to destroy a healthy economy. Feel me?

    Honestly? The LEOs of today, based off of what limited information I have gathered, pale somewhat in comparison with the LEOs of yesteryear. That is to say the quality has dropped a fair amount with regards to the new recruits. Now, it's possible that the quality has remained the same, and it's only with the advent of new technology (cellphone cameras) are we finding out just how poor that quality has been all along...however, there are some limited indicators which suggest it may have been, on average, better at some point in the past.

    Investigators who need information spoon-fed to them, troopers who need to be constantly reminded of the laws they are supposed to be upholding...it's pretty bad.

    How does this relate to GPS? Well, as I outlined in a post a while back, officers are more reliant on technology today than times past. Mind you, I said reliant, not augmented by. As such, a typical officer cannot be guaranteed to actually memorize the various roads and streets that make up their own town / city, let alone the surrounding towns / cities. So, if you manage to knock out their GPS navigation systems, it's possible that they will not be able to find a route, let alone a quick one, to the scene of the crime nor plot an intercept course to pursue a suspect if he / she is still at large.

    If you pair up GPS jammers in concert with radio jammers, you can prevent officers from being notified about a crime in progress, as well as prevent them from finding their way to the scene (thus buying yourself time) is they manage to get around that (by using their cellphones or something more creative). In the event of a chase, officers typically need some level of communication to box-in a suspect (to get a car on either side, one in back, one in front, to force you to slow down). And so on.

    Since this is taking place in the UK, it could be a prelude to something 'interesting': rolling with the cliches here, someone planning a bank heist or to swipe the crown jewels. Or not: it could easily be a broken device broadcasting on the wrong channel, with the owner unaware; a broken CB radio in California once overpowered cellphones in the surrounding area, and no criminal intent was found. Or a prank.
