    According to Brett <[email protected]>:
    Which pulsars are spinning too fast? Reference please!
    https://en.wikipedia.org/wiki/PSR_J1748%E2%88%922446ad#:~:text=PSR%20J1748%E2%88%922446ad%20is%20the,was%20discovered%20by%20Jason%20W.%20T.

    Our sun spinning at 42,960 revolutions per minute would exceed the speed of >light at its surface, much less be able to hold together.

    The theory is wrong.

    Huh. Using the advanced research technique of reading as far as the second paragraph of that Wikipedia article, we learn that if we assume the pulsar is less than twice the Sun's mass, typical for neutron stars, its radius is 16km and the surface velocity is about .24c. Neutron stars are, you know, really dense because they're mostly made of neutrons.

    But sure, a Dyson sphere, whatever.
