Reynolds is an astrophysist, so I'd hope he'd get that sort of thing
right.
Plugging the numbers into the time dilation equation isn't exactly
rocket science.

99% c gives a Lorentz factor of ... *types on HP-11C* ... 7.09.
Which would agree with the approximate figures above.
Hp-11C...Hp-11C... That was one of the HPs that used "reverse polish notation", right? I remember that being confusing and delightful, all at
the same time.
