  • Just for fun I did the Maths.

    Rougly a 100ml glass of anti-water has 100g of anti-water (assuming same density as normal pure water, which is around 1).

    When anti-mater contacts mater it transforms into energy according to E = mc2 were E is in Joule and m is in kg.

    For 100g of anti-water to turn into energy in this way it also needs 100g of normal mater, so the number is doubled.

    Using the rounded 300,000,000 m/s for the constant c, the energy released by the annihilation of a 100ml glass of anti-water (and the matching 100g of normal mater) would be 1.8e+16 Joules, equivalent to around 4.3 Megatons of TNT.

    So basically a regular nuclear bomb.

    PS: I actually expected it would be much more energy before I did the maths.



  • It’s that but not just that.

    Notice people paying attention to actors and musicians on social subjects, even though the domain expertise of those people is acting and music respectivelly, not sociology.

    (You can even see it here in Lemmy: some actor or other says something on a social subject somebody agrees with and they make a post here about it, under which tons of people write about how they totally agree and it’s so good that said person talked about it. If anybody points out “they’re an actor, not a domain expert” they’re assumed to be of an opposite opinion, even of an opposite political side)

    I think there is a broader problem of people’s trust on certain subjects being far more highly positivelly correlated with the fame of the advice/opinion giver than with domain expertise.

    Your point about rich people does dovetail with this - rich people are often treated as celebrities by the media.

    PS: Also there are a bunch of interesting effects around this - for example the more somebody’s opinion on something is talked about on the media, even negativelly, the more they are perceived as having a relevant opinion on that subject (the so-called “Halo Effect”).
