First, it’s important to explain what a dimension is.

Imagine a wooden table in a kitchen.

Do you think it’s real? You think reality is real?

I think it is, because we, including my dog, can observe and experience it.

If it wouldn’t be real, then we wouldn’t be real, and then our argument would come from something that isn’t real, so it wouldn’t matter anyway.

So, let’s say it exists: I think that’s a pretty safe bet.

Let’s try to determine what that wooden table in the kitchen is:
• I only glance at reality. So from my perspective, I only see whether there is something strange about the wooden table.
• My mother, on the other hand, always spots whether something has changed since the last time she has seen the wooden table. She also touches the table; she wants to feel the table with her hands.
• My brother knows a lot about wooden tables: my brother sees the table in terms of quality.
• If I bring a table maker, that person will probably see the construction or the origin of the wooden table.
• If I bring a mathematician, maybe only the spatial dimensions are seen.
• My dog sees the table as a jump to food on the table. The dimension “sitting at the table” doesn’t exist.

This all may seem fairly obvious.

But it’s important to note that one thing is never one thing. A wooden table is multiple things at the same time. It exists in multiple dimensions simultaneously.

Depending on who looks, observes, or experiences the wooden table, it’s something else. We all see a different side of the same thing.

And the way we look at the same thing is unimaginably different. You wouldn’t believe what I see in reality versus you.

What is the most fundamental fabric of the universe?
Imagine we want to observe that. That would work exactly like the wooden table. What it is depends on how and who looks at it. It’s something different from every viewpoint, every angle. It’s multiple things at the same time.

So you can’t say “this is” at the smallest level. You can’t say it’s “quantum mechanics.”

The fact that it’s small and fundamental is irrelevant, because you can still see it from another side.

I have a strong feeling that physicists underestimate (1) the amount of dimensions there are (I have found hundreds, maybe thousands), and (2) only look at reality with physicist’s glasses. You could, for instance, easily argue that molecules are a way of looking too. It looks like a molecule when you look at it from exactly that angle.

Numbers are also a good example. I am still waiting for the first number that flies around in my room, but I have never seen one in baseline reality.

I have to be honest:
I find physics interesting, but what I am most fascinated by is psychiatry, where they are world champions in making observational mistakes.

What you can’t do, for instance, is take a group of people and give them a generic label like ADHD. You suppress the level of uniqueness in people, and that everybody’s ADHD is a little bit different, and therefore ADHD doesn’t exist. A person is both unbelievably unique and multiple things at the same time, which makes psychiatry prone to making every textbook mistake possible.

For instance: if people who grow up in bad environments have tendencies to have ADHD, and on the other hand there are people who have a “creative” energy for generations in their bodies, then you can’t automatically assume that ADHD doesn’t exist. Well, it does, but two ADHDs have nothing to do with each other, so that means you have to put the label in the garbage bin.

Back to physics
Since my wooden table exists in every dimension possible right now, you can imagine why it doesn’t reveal itself constantly in every dimension. It would take too much energy. So a part of this universe is always “idle,” waiting until it gets observed. Or in other words: reality only exists when we observe it. But it also exists when we don’t look, because it exists in multiple dimensions at the same time.

I think this is also what a black hole is: a place where the hidden dimensions stay hidden, because we can’t observe it.
