The observable universe is also way denser than a black hole of equivelent radius (black holes get lower in density the bigger they get) so one way or another we are in a black hole in the sense that somewhere out there is an event horizon through which you can never leave, just not in the traditional understanding which only really applies to ‘small’ (every single other) black holes.
So from a mechanics standpoint what are the pros/cons of a bullpup design? off the top of my head I’m guessing more barrel length but less space for any kind of recoil supression?
