Humans don’t pop in space: What really happens might be far more disturbing

A sudden exposure to the vacuum of space won't make humans explode, contrary to Hollywood depictions. Instead, the real dangers are rapid unconsciousness from oxygen loss and internal tissue damage from ebullism as bodily fluids vaporize. Victims lose consciousness in about 10 seconds and face likely death within 2 minutes without immediate rescue and repressurization. While dramatic, the effects are mostly internal rather than visibly explosive.
