Yeah, I make lot's... I mean lots of mistakes like this.
Better if I'd of said "Sol's mass" I'd guess but still just more of a
reference to Eddington rather than a clear picture of the concept.
Also the idea that a warp/wrinkle is related to bending light is naive at best.
But the denser you pack the mass the smaller the wrinkle you'd think
you'd get huh?
As I recall the Earths mass would need to pack down to roughly ping
pong ball size to get to the black hole stage.
I figure I span about 12 ping pong balls in an average step.

Nice... I'm always interested in limits.
CNO cycle dominate stars to go neutron.

This knocked me down for a few hours...
I'm guessing these would be harvested as making them implies a level
of tech that would seem to exceed the need for fuel tanks pretty much.

Is mythril elemental do you think?
It seems like it but that bugs me a bit.
Stabilize Hassium or something?
Or is it in the copper column, or titanium?
I think I prefer a natural alloy to trying to fit the stuff into the
fusion reactions but of what?
Unobtainium can get worse depending on what one is asking of the stuff.
Perhaps mythril comes from early super-massive population III stars.
Assuming only the most massive of these could do the trick and these
are/were pretty rare then Middle Earth could be in trouble if the
resource harvesting, galaxy hopping aliens get a wiff of the stuff.
