    whats up with all the comments making analogies with AI torture repository?

    One might measure the "amount of computation going on" as a proxy for consciousness, but "number of dissipative logic gates" can't be right since one can construct larger reversible circuits containing the same computation (and hence dissipation is a poor measure), although one could then use the total number of bits (including trash bits) as the measure.

    but I don't understand why particle physics?

    having all other comments (at the time of writing) be about consciousness of individual particles, seems to indicate these commenters specifically believe particle physics or antimatter to directly describe consciousness?

    Or is this some kind of "disinfo inoculation campaign" to render us immune to "sentient rights propaganda"?

      It's definitely just jokes due to using the word 'trap'. You might need to get some sleep lol

      I don't see comments on SI's website. I assume you mean here. Those are jokes.

    I kind of want to know how they safely deal with its release (destruction)

      If it's a single particle I don't think there's much to worry about?

      It's one particle. It's not a bomb.

      E=mc*2 but m is really really tiny

    I hope they took precautions against the Camerlengo stealing it

      Positrons are just as Catholic as electrons: they both have the same mass!

    Does this hurt the positron?

        It could have been an entire universe, like ours, if some theories/cosmologies are correct :)

    of course the cyclotron going clockwise.

    That's matter cruelty. We need more ethical ways to study those poor things. Does anyone know what happened after the experiment ? Did they finally let it go?

      It was given freedom at the end of experiment, and was immediately eaten by its abundant natural predator, just like it happens in nature.

        But antimatter rights antimatter? Or do they become lefts.

      It's worse than that. They annihilated it completely.

      I was going to comment "I bet it's pissed" and then worried about drawing dang on myself, but you started it... Also: https://www.facebook.com/watch/?v=1254917172263794.
