I feel like blame is the very obvious factor missing from most descriptions of trolley problems I’ve seen.

“Will it send me to jail?” is a highly important question for something that might easily be considered murder even if it does prevent other deaths.

Yes. 1/2 c is super fast still and gravity that strong would have effects like noticably bending outgoing light.

Neutron stars are right on the verge of becoming black holes and are incredible.
