Re: Calculate Mass from Time Dilation and Radius

The analogue of gamma for the Schwarzschild metric is 1/sqrt(1-2GM/(rc^2)). The "time dilation" ↶ The time dilation range I'm using is 0.0 - 1.0. Where 1 would be infinite time dilation. Wanting it to go from 0 to 1 isn't unreasonable, as that could just be the reciprocal of the usual figu...

Re: Math: Fleeting Thoughts

Still, the coefficient of inbreeding for a son who's also a (half-)brother is four times higher than it is for the offspring of (non-double) first cousins, which is usually the point where some jurisdictions start allowing marriage. (Though I don't know how often those laws distinguish between doubl...

Re: Math: Fleeting Thoughts

If someone's son is their brother, they reproduced with their mother or father. Which, in addition to having a much higher rate of defects, is also fucked up in loads of other ways that often wouldn't apply to (even double first) cousins.

Re: Calculate Mass from Time Dilation and Radius

1^2 = 1, and 1/(1/x) = x, so as you've written it,
1-(1/((1/(sqrt(1-(v^2)/(1^2)))))) = 1-sqrt(1-(v^2))

Re: Stars in background of deep-sky photos are in foreground

Any delta-v you spend above a certain latitude isn't going to help you get into an orbit with a lower inclination than that. Basically, acceleration can change the plane of your orbit, but it can't possibly change it to a plane that doesn't actually include your own position. It also has to include ...
