Why is there something instead of nothing?

in a conceptual vacuum, yes thats exactly what qm describes, there is even a famous albert einstein quote regarding this implication. "I like to think the moon is there even if I am not looking at it."

>"I like to think the moon is there even if I am not looking at it."

Isn't that the opposite of what you said?
Also, what counts as observation?

Look, if you're going to claim that the rules of time could at some time/place be broken or different than they are now, you've gotta have some data to draw from to make that conclusion.

For all we know, time has worked the way it does for however long time has been around, if that's even a valid way of putting it. Maybe I only believe this because I've never even really attempted to understand the math and physics behind the Many-Worlds theory, but I see no logical reason to assume that there are other times and existences beyond what we can perceive. This does not mean I believe that there is nothing that is beyond human perception or recognition, it means that I do not think it is wise to draw conclusions about things we have little to no information about.

>didn't create the universe
Did he say you "created" it? He said you caused it to be the way that it is by asking about it. Essentially a roundabout way of saying you are something, and that makes you a part of everything. So you don't really have to question existence because existence precedes questioning.

>what created physics
You're thinking of physics as an object that can be interacted with that simply popped into existence. Physics is a mathematical and scientific description of the processes that the universe functions by. If you're asking what governs those, you're asking about what process guides absurdity and arbitrary rules, and I don't really think anyone can give you an answer to that question.

Why must individual, subjective experience be special? Is it not better for it not to be special, but common, and happening all the time?

Regardless, your own subjective experience arises as a result of your thought processes, and those arise as a result of the firing of synaptic responses in your brain and nervous system. Obviously, you have your own brain and nervous system that is not directly connected to anyone else's, and that is why you experience existence through what is essentially projected sensory data processed through that nervous system. You don't see through "eyes", you see through YOUR eyes.

>inside each other

My mother went inside my father?

You can only experience existence through subjectivity. The universe does exist objectively, but we cannot perceive anything objectively because we are not everything. When you cease, your subjective experience of existence ceases, and I'm not sure if we as human beings bound by the laws of existence can ever really retrieve information from beyond that point.

that doesn't mean I will have the consciousness of the exact clone of me

not all scientists believe in many world theory
