general question about how a market crash happens

hi.. i got to thinking after the unusual rise and reversal yesterday that nobody seems to know exactly who began the reversal.. how it works.

does anyone have any insight into this regarding:
1) who triggers the reversal is it one large fund with a person deciding it or are market makers colluding to stage a large broad reversal.. or was it all algorith/computer driven?

2) how was such a broad selloff across all segments triggered and maintained to the downside? are they dumping ETFs and that results in the large broad selloff or is someone giving the order to dump it all?

3) why is there no one that has the answer if someone or a group of people seemed to have decided to sell at a specific point in time?

i'm just trying to understand the mechanics of such an epic rug pull
