The wave collapse sends the wave back in quantum time making it appear to collapse and disappear. Penrose explains it well in his interview.

If anyone shows me negative time, I will ask why they can't see anti-gravity. Unless you can show it.
Penrose is respected, but respect doesn't guarantee he is right. Theories are still theories until lift-off, Donuel. Should we toss a coin on it?

Mind you, I feel light-headed just thinking about all this.
