    Double Slit Experiment

    Worth noting that Mr Goat has used up his five posts and won't be back till tomorrow....

    "Microwave five minutes"...

    You know that's partly because of standing waves? (Which is way they added rotating turntables.) And you can use that to measure the speed of light? Good point. If you are cooking up a mountain, you need to be sure you are measuring the mass and not the weight, as well as accounting for the change in boiling point.

    You think you've got problems America...

    There is always theft and murder. That doesn't mean we should just shrug and ignore it. "Bloody victims, complaining about having their stuff stolen. They should just get over it." That may well be true. And the propaganda (whether it was Russian or from the Leave campaign) exploited that by playing on peoples fears that the EU would mean more of those weird foreigners coming over. Even though most immigration into the UK is nothing to do with the EU. And immigration is a net benefit. And ... But the argument was certainly won on emotional rather than rational grounds.

    I'm not sure it assumes that. Unless your question requires that the result be different by 10%, in which case it is impossible to answer because we don't how people will vote. But we can estimate the time it will take for the make up of the electorate to change by 10% (which looks to be roughly 3 years). However, in this particular case, we do know that those who have left the voting pool overwhelmingly voted one way and those coming in generally voted the other way. So with a 6% change in the electorate we might expect, say, 3% swing in the result (I could look up the numbers and get a more accurate estimate, but I'm not sure it is worth it for a discussion of the general principle). It seems to me that if you are going to ask "The People" for their opinion on a major decision that will take years (possibly decades) to fully implement, then it makes sense to track their views in some way as the process goes on. For example, are they happy with the current withdrawal agreement (anyone who wants to leave the EU and minimise the damage to the economy should say "yes" to that). Then, in a couple of years, "is this the sort of future relationship you want with the EU?" Then, further down the line, "is this the sort of trade deal you want with the US, China, etc?" But if one thinks that those questions of the preferred trade deal with the EU or the US should be left to the "experts" then we should never had the referendum in the first place!

    Double Slit Experiment

    That sounds like Wheeler's "Many Worlds" interpretations: all possible outcomes exist in "different universes".

    What eats black holes?

    Profound, depressing and also slightly cheering! Yes, and yes! Could be worse, then.

    Time and mass (split from Time...)

    Time is defined mathematically and does not require the presence of mass. For example, we can study theoretical universes that have no mass or energy but still have space-time coordinates. And a photon has zero mass. That is what massless means.

    About QM Interpretations

    This is a "hidden variables" model. This is ruled out by Bell's Theorem. Also, the fact that things are probabilistic, doesn't mean they can't be accurately measured. We can measure to whatever precision our technology allows.

    You think you've got problems America...

    Absolutely. But with a large enough majority, you are not going to be flipping your constitution back and forth every couple of years. Doing it every couple of generations is not unreasonable. (And Brexit is, effectively, the equivalent of a constitutional change: it requires hundreds of laws to be modified or created, new civil service departments, new agencies for testing/approving all sorts of things. And that's before you get to the supposed benefits like spending decades trying to get something close to the large number of trade deals the country currently has around the world.) Does the constitution include the ability to abolish itself? What sort of majority would that require!? (And I wasn't saying that having a constitution is necessarily a good thing; there are probably advantages to the UK's less formal approach.)

    Then you would be wrong.

    Most countries have a well-defined mechanism for changes to the constitution (*). This typically requires either a popular or parliamentary vote with a significant majority (like 67% or 75%). I'm sure one could argue for ever about exactly what the majority should be, but I think the purpose is to ensure that it is convincing and, presumably, wouldn't be changed by a relatively minor change in demographics. And maybe even that it represents a majority of the population, and not just those who voted. People might feel differently in a few generations, but things can be adjusted again then. With a near 50:50 split (of less than 100% turnout) it only takes a small change in the number able to vote, or the employment rate, or the proprietor of a newspaper/TV channel to swing things one way or the other. (*) Note that the UK has no such mechanism as it doesn't have a constitution. That is another reason this is such a shitshow.

    Alternative Model of Space

    You presented no science. Just some vague waffle.

    We know that. It is quantified by general relativity. Is that what you are talking about?

    And the fact that Cameron promised it would be.

    Yep. I'm keeping an eye on it!
