I thought touhou poster were supposed to be smart.

I think if the sun made of 1000 collided with a sun made of -1000 they wouldn't crack but instead cancel out and make a sun made of 0.

fracture mechanics basically stops existing at impact speeds greater than the speed of sound(~10s of km/s). Hypervelocity impacts are best modelled as fluid flows in some cases.

Although relativistic considerations of rigid body dynamics exist since over 100 years, but it's completely fucked

I'm pretty sure fracture science is outside the scope of rigid bodies.

I'm sorry I'm not smart enough to invent relativistic fracture mechanics.

Neither of those things are what constitute "suns".

of 1000, -1000 and 0 what?
