Fraser: Right. Pamela: And so any time you hear a noise in space, if you hear explosions, thatâs probably your own spacecraft, and the noise is transferring through the hull and through the air in your spacecraft. Other than that, youâre not going to hear explosions.
Sure, explosions in cinema are greatâthey propel cars over otherwise impassable chasms and give heroes something to resolutely walk away from. In real life, explosions of any appreciable size are terrifyingly deadly. This is what really happens when you're too close to the blast.hen a bomb detonates, the energy released from the explosion radiates outward in all directions at once at speeds between 3 and 9 km per second. As this sphere of energy expands, it compresses and accelerates the surrounding air molecules into a supersonic blast wave.
