Standing outside of the Universe would be an excellent capability.

We'd understand the universe far better if we could do that. But, we cannot. We are inside of our universe, and can only observe it from that perspective. Some people who are cosmologists have hypothesized in various ways about the universe. We do possess imagination that lets us imagine things we cannot observe. For example, one theory about the universe is that it is like a bubble, existing alongside other bubble universes. The nature of those bubbles prevents us from observing other bubble universes from inside of one of them.



That image above is an artist's rendition of what such bubbles might look like. It, too, is an imaginary concept of universes. We still cannot step outside of our own universe, though, except through our imaginations, so this is merely a hypothetical exercise. It cannot be tested, and no evidence is available, so it will remain a hypothesis.

We can also imagine an all-powerful entity outside of the limited natural world we experience. But, imagination is not evidence. Whether we call it imagination or faith, we cannot actually observe or experience what is outside of our physical reality. The difference between science and religion is that science differentiates between hypotheses and observable facts, while religion does not. Religion asks us to believe that supernatural entities like deities actually exist and to treat them as factual.

I'm an atheist. I cannot believe that sort of thing. I might find it interesting to think about, but I cannot believe it. Cosmologists don't ask me to believe that the bubble universe hypothesis is factual. Religionists do ask me to believe that their deities exist. One is science; the other is fantasy.
