Of course, I'm not expecting you to support the idea in the answers, but simply mentioning its conclusion:)
People like to pretend they are doing fine by using a cognitive algorithm for judging that is riddled with availability heuristic, epistemically unsound dialectics and other biases. Almost everyone I meet is physically and emotionally unwell and shies away from thinking about it. What rare engagement does happen occurs with close intimates who are selected for having the same blind spots as them.
It's like everyone has this massive assumption that things will turn out fine, even though the default outcome is terrible (see obesity and medicated mental health rates). Or they just have learned helplessness about learned helplessness.
Traversable wormholes, were they to exist for any length of time, would act as electric and gravitational Faraday cages, i.e. attenuate non-normal electric and gravitational field exponentially inside their throats with the scale parameter of the mouth size/throat circumference. Consequently, the electric/gravitational field around them is non-conservative. This follows straightforwardly from solving the Laplace equation, but never discussed in the literature as far as I can find.
Not new, but possibly more important than it gets credit for. I haven't had time to figure out why it doesn't apply pretty broadly to all optimization-under-constraints problems.
2 of them:
- there's a lot of advantages to video-recording your life (I want to write much more about this, and only took time for a very brief overview so far https://matiroy.com/writings/Should-I-record-my-life.html)
- if MWI is true and today's cryonics is good enough, we can use quantum lottery to cryopreserve literally everyone for the cost of setting up a quantum lottery + some overhead (probably much less than 100k USD)
