We're all wondering when this bubble will burst, but what if it already has? The flash of a distant explosion might not look like much, but only until the shockwave reaches you
@gabrielesvelto It won't probably explode, but more or less gradually deflate the balloon. Who's on top of it will fall, others will witness the "gentle tsunami" of the empty ballon, that is maybe going to sweep them away, while they still don't understand why and what.
