You can picture an explosion as a sudden, violent bursting outward with a loud bang — something breaks apart and throws its energy out all at once. From that single image come the deliberate blast, the figurative bursts of number or feeling, and the sheer noise.
From the word’s history
From Latin explodere 'to drive out by clapping', ex- 'out' + plaudere 'to clap'. It began as a theatre word — clapping and hissing to drive an actor off the stage — so a loud noise driving something out was baked in from the start; only later did it mean a violent, noisy bursting.
源自拉丁文 explodere（用拍手把人趕走），由 ex-（向外）+ plaudere（拍手）組成。它本來是劇場用語——觀眾用拍手、噓聲把演員轟下台，所以「用巨大聲響把東西趕出去」一開始就在字裡；後來才變成「猛烈又吵鬧地炸開」。
