  • And 1/2c is a pretty middle of the road escape velocity for a neutron star.

    The lightest known neutron star, at 1.4 solar masses has an escape velocity of right around 1/4c, while the heaviest at 2.35 solar masses is 3/4c.

    All of which assumes the neutron star isn’t spinning. Equatorial bulging caused by the rotation reduces the escape velocity at the equator relative to the poles and depending on whether or not you launch with the direction of the rotation you might be able to subtract the rotational velocity from your escape velocity.

    As an example, in the case of that 2.35 solar mass neutron star, it has a rotational velocity of approximately 0.24c. So of you launch with the rotation you get an escape velocity of 0.5c, whereas if you launch against it you’re looking at more like 0.98c.

    Given that nowhere in the article does it say that 14% of people exclusively play on pre-2000 hardware I don’t find this that surprising.

    I’m more shocked by the last statistic, 11% of American households still use fax. Fax? Fuckin’ why? That’s like saying people still listen to music on Edison cylinders.


  • For most things if I’m gonna be waiting more than a few weeks, I’ll let myself kind of forget about it and then enjoy it whenever it happens.

    That said, I didn’t do that for The Wheel of Time TV show. I learned about it relatively late; a few months before release, and then spent a lot of time reading up on it, looking into the cast, watching trailers, interacting with WoT communities online, and just generally getting kind of hyped. Most people seemed pretty positive about it. It was looking like it might actually be a good adaptation of one of my favorite book series.

    Then it came out and it was the single most disappointing adaptation I’ve seen since Eragon.
