Thank you for the detailed answer. Now the wonder is if you would feel the recoil of the gun, or if you and the gun would mover perfectly as one. Friend 1 thinks you would feel the gun as it imparts its forces on you, but wouldnt feel the acceleration backwards

So what im hearing is, using a recoil suppression system in space would actually CAUSE recoil, because the forces would be propelled downwards in an attempt to counteract recoil in earth gravity

Micro gravity is probably what I meant, Im definitely not a scientist. Whats the difference?

Also I thought mass would still be relevant, just couldnt work around how. Is it because the energies from the bullet are being transfered into the recoil dampners/springs, but theres nothing counteracting the weight of the bullet?
