What is Retrocausality? What's superposition got to do with it?

What is retrocausal - how does retrocausality happen? And with a Multiverse of options for Superposition to choose from, how is that we get to exist in a single Reality at all?

This video unearths a few quantum conundrums relating to this question and looks at the undercurrent of Time as it really is, instead of the way we tend to think about it.

The angles of a triangle only add up to 180...

You could be onto something here… the collapse of wave-functions, and the notion of time as a wave function is quite fascinating . It deffo has merit and you should carry on researching your ideas . Ive always wondered about the structure of space time, and if time is a wave-function then space ?

You are absolutely nuts ...but sooo charming....lets go for a pint full of quantum foam's 😂?
I am based in London
....if I had to guess your Quantum location...I would say Bristol/bath ? But then again, you are probably on superposition. Lol x

Hmmm. Nothing is clear to me. I guess because I don't know much about it. Do you understand that the wave collapse occurs in the present and the wave states, which resulted in the collapse, are a past that affects the instant of the collapse and subsequent states of the same?
That the collapse and its subsequent states affect the wave state prior to the collapse?
That the present has diffuse limits towards the past and the future?
Like I said, it's not clear to me. :)
