This is nonsense. The fact is that:
firstly, sound cannot exist in a vacuum due to the absence of an elastic medium;
secondly, the moment of the explosion lasted for about 10 v - 35 degrees of seconds, which makes it very difficult to record. In addition, before the explosion, in fact, there was nothing, so it is difficult to imagine what was happening at that moment. Hence the name "Theory of the Big Bang".
Well, how, we flew closer to the Singularity, put the iPhone on record, waited for the moment of the Explosion, then posted it on Twitter. And so it happened.
