Randomness in quantum mechanics

[gen x]

What quantum physics(randomness) tells about our reality?
everything is random, there is no cause-effect world?

everything is random, there is no cause-effect world?

The probability distribution still has causes and effects.

What quantum physics(randomness) tells about our reality?

That there appears to be some inevitable stochasticity in the world.

there is no cause-effect world?

QFT respects the causal structure of relativity, so has clear chains of cause and effect.

It is not deterministic, if that's what you mean. You can only predict future probabilities, not exact paths. The randomness averages out over many particles, which is why the large scale world appears deterministic.

What is mechanism for randomness?
Determinism is emergent property of random processes?
We dont know what each particle do, how path of one single electron around nucleus looks?

What is mechanism for randomness?

What would it mean for something to be a mechanism for randomness?

Determinism is emergent property of random processes?

Yes.

We dont know what each particle do, how path of one single electron around nucleus looks?

What does this question mean?

What is mechanism for randomness?

We don't have an answer for that. It's built in to our most fundamental theory. I don't think it's even clear that the question makes sense.

Determinism is emergent property of random processes?

Essentially, yes.

how path of one single electron around nucleus looks?

I don't think an electron has a path around the nucleus. It has a probability distribution 9f being found in different places.

Nothing make sense if you go deep enough. But I hope for few hundreds/thousands years things will become more clear.

Some physical laws that governing each particle behaviour

[Matterwave]

Nothing make sense if you go deep enough.

Or if you ask vague enough questions without putting in any effort to actually learn the material.

Some physical laws that governing each particle behaviour

"A mechanism for randomness [would be] some physical laws that govern[ing] each particle behavior"? What do you mean by this?

 

[Dale]

Some physical laws that governing each particle behaviour

That we have. https://en.wikipedia.org/wiki/Standard_Model
