Re: Any GURPS stats for black holes, pulsars, etc?
I was wondering where the 10x solar mass Blackhole came from. I don't expect Doc Smith to how about the Blackhole at the center of the galaxy back then.

Average mass of a stellar black hole.

So just take the square root of five times the blackhole's mass to find it's telekinetic (one direction only) Strength.

Re: Any GURPS stats for black holes, pulsars, etc?
I'm wondering at what point that detail no longer holds true - where the radiation becomes stronger than, say, five hundred thousand d6 damage per second.

I've been eyeing 4e's Spaceships 5, page 40, which contains a table describing how much dDmg a STL ship takes from ablative dust-grains. However, that damage appears to scale with the Lorentz factor of how fast the ship is going, which kind of breaks down when an FTL drive is in play. Still, it gives some potentially useful numbers. At 0.9c, the Lorentz factor is 2.294, and a ship suffers 48 dDR per year. (Or 48*3d=144d6 dDmg, if dDR runs out.) That would mean that at Lorentz 100, at 0.99995c, a ship would ablate 4,000 dDR per year (or 12,000d6 dDmg, or 120k d6 dmg per year, or about 48 dmg per hour). I just might be able to work up some further numbers for denser-medium relativistic impacts based on that. I seem to recall some mention that damage-scales were tweaked between GURPS 3e and 4e, something about squares versus cubes. Does anyone know what the factor of change (if any) was?

Re: Any GURPS stats for black holes, pulsars, etc?
That doesn't sound right. For a homogenous body, its HP equal 8 times the cube root of its mass (in "pounds," because GURPS tends to treat mass and weight as interchangeable).

Re: Any GURPS stats for black holes, pulsars, etc?
So, that would give an average stellar black hole a ST of around 35 billion or so?

Re: Any GURPS stats for black holes, pulsars, etc?
Well, an HP. It doesn't have an ST, having no musculature or comparable structures, and its telekinetic ST could be anything. Though I suppose you could estimate it from the force needed to escape from it (if you weren't inside the event horizon).

Re: Any GURPS stats for black holes, pulsars, etc?
There are most probably no such things as event horizons in the Lensman universe. Places where the ether is so drastically warped that not even LIGHT ITSELF can escape, perhaps. But that would be without infinite time dilation or any other relativistic phenomena.

Spaceships beam damage table. Treat as a neutral particle beam. Four by ten to the nineteenth MJ. Nineteen powers of ten from 3 MJ => nineteen doublings from 3 dice decadal damage. Three million d6 of damage going "dink!" every second. Quote:
