Afterlife

[Alex K]

Your father was a hamster, and your mother smelt of elderberries!

You can do better than repetition! Thou art a flat minded, borborygmus dompteuse of puny stature! Hah!

Heh

No, Dark Matter is not considered crazy. There is multiple evidence for Dark Matter and there are very simple and plausible ways to explain it. There is no comparable plausibility or any evidence for afterlife claims. Just because science has open questions, that doesn't mean your toy fantasy is real.

Can you explain dark matter simply and plausibly to me?

Of course I don't know which is the *correct* explanation because we lack the data to say. But to just give you one relatively simple explanation: The electrical dipole field of the neutron is undetectably small, and this fact seems odd in the Standard Model, where there is no reason why the corresponding free parameter should be so exceedingly small (though it could be zero without running into theoretical inconsistencies, this seems like an unlikely choice). To explain this fact completely unrelated to Dark Matter, one can promote this free parameter to a dynamical field called the Axion field by a not very complicated extension of the theory. One can then calculate that this field would retain residual energy density after the universe cools below the temperature where the strong force starts binding quarks and gluons. This residual energy density of the axion field would have precisely the correct properties to explain all effects connected to Dark Matter. The beauty of this approach is that it was not invented to explain Dark Matter but something else, and yet it also explains Dark Matter. Those are the best hypotheses. The Axion Dark Matter hypothesis has only been partially tested experimentally so far, but will be thoroughly tested by the next generations of so-called Axion Haloscopes, which could directly detect these hypothetical particles by converting them into microwaves in a powerful magnetic field.

Here's a currently running experiment of this type:
