We experience it every moment, yet no one can fully explain it. But there's a simple way to understand time, and once you see it, time, gravity, motion and force all make sense as one thing.
@Briankeating thats a perspective illusion. It's still only 3 orders of magnitude. Multiply the heat of -40 centigrade by the same amount and you have 233.000 centigrade.
Does space really have a size?
We ask whether space is finite or infinite, but that assumes space has size in the same way an object has size.
I think that assumption is the real problem.
To answer that, I think we first need a better understanding of size, and its relation to space, distance, and location.
What is the location of an object?
Is it the center? The surface? The whole area it occupies?
We can debate this, but the truth is that location is fuzzy. Location is a mathematical idea imposed on something that is not itself a location. An object has extension, surface, relation, and boundary. It does not simply have one point called “where it is.”
So the way I see it, size is a measure of locality.
Something that has size is local enough to be bounded, compared, and quantified. But size also requires an inverse. Something that is not the object. Not bounded in the same way. Not directly quantifiable as a thing in front of us.
We call that space.
The farther an object moves away, the smaller it appears. It loses surface, detail, brightness, and certainty. This is not only a change in visual size. The object is exchanging state with what we understand space to be.
The object has brightness, while space is dark. It has surface and detail, while space has no visible surface or detail. It is local, while space is non-local.
So as the object moves away, it starts to take on the state of space from our perspective. It becomes darker, less detailed, less certain, and less local. If size is a measure of locality, then the object becomes smaller because it is exchanging locality with space.
I use the word space instead of universe because the universe is already a specific understanding of space, often translated through tools like telescopes. A telescope magnifies one perspective of space: light. It is extremely useful, but it is still an isolated perspective.
Every perspective has an edge of space.
On a clear night, the stars you can see are inside your visible edge. The stars you cannot see are already dark to you. With a telescope, that edge moves. With another instrument, it moves again.
So it is not quite right to say we do not see the real edge of space. Every perspective has an edge. What changes is the observer or the lens.
Knowing that interaction is a state exchange, the size of space is likely the result of an interaction between measurable locality and what cannot be measured directly.
Measurement requires interaction, and interaction forces change. So from the perspective of a moving object, its own locality interacts with space. Space does not become physically small or bounded like an object. It becomes more local relative to the frame that moves through it.
That interaction creates an intermediate state. We try to understand space as if it has physical size, the way a room or an object has physical size. But space is not an object in front of us. It is not local in that way. Our own locality forces a relative notion of size onto it.
We cannot measure non-locality directly. We translate it into distance, horizon, darkness, and uncertainty.
Space does not simply have a size waiting to be found. Size appears where locality interacts with non-locality.
Beyond that relation, size stops being size as we know it. It becomes a gradient along which meaning gradually changes into something else.
This is what I call a relational gradient.
And if the size of space changes meaning with locality, what does that do to our idea of time, and to the beginning we call the Big Bang?
Many people live like they are walking along the edge of a cliff, constantly looking down at what they fear.
Live like you are already hanging from the edge, looking up at what you want.
What defines a creator though? We say matter creates gravity, light creates heat. So we follow causality which is driven by what we observe the direction of time to be. But time stops at the speed of light and inside a black hole. So that breaks causality from that perspective. How can you create something if you dont have a causal starting point and what does that mean in terms of a creator?
A New Perspective on Interactions
We usually think of it as something happening between things. But it may also tell us something about what a thing is.
Interactions can be understood as exchanges of state.
When something gains heat, loses speed, changes pressure, or shifts direction, we say its state has changed.
But what is a state?
A state is determined by properties. And properties are not just things an object “has.” They are smaller perspectives that make the object coherent.
Color, speed, hardness, texture, size, shape, temperature.
Each of these reveals the object from a specific perspective. None of them is the whole object by itself, but together they form the larger perspective we experience as a thing.
So if properties are subperspectives, and state is determined by properties, then an interaction is not only a state exchange.
It is a perspective exchange.
When two things interact, their properties align and find an intermediate state. A different angle that reveals a new perspective.
Could this mean that everything we observe to be different can be viewed as the same thing from a shifted perspective?
You should write for movies like star trek where they use that kind of scientific word salad. Nobody will be able to follow your explanation. I can't extract any logical mechanic from this. Try explaining it to a kid in primary school. If you can't explain it simply you don't really understand it. How do you explain black holes this way? There must be an enormous amount of light coming from them yet they are black and consume light.
It seems as though you want to explain gravity as some sort of inverse to light. If that is true then they should be part of the same wave like electro and magnetic. Without light no gravity and without gravity no light. They should then be co-emergent. But I don't see that.
You have to be careful not to jump to conclusions. You need strong arguments not just a hunch that works in your mind. What collapses? what does that mean? Gravity attracts and a centrifugal force is an implied force. it emerges from the expectation that an object will orbit when it really wants to go straight. The centrifugal force is then a direct result of the inertia that works against the expected orbital motion.
@QihanZhao09@PhysInHistory This is probably the best question in this thread. The only one I don't know how to answer. And I love that story, sounds like something I could have written :)
I think so, but it's not likely 1 theory. Every theory has a basis in specific meaning from a specific perspective, usually the human perspective augmented by tools and measuring devices. But because the human perspective is not the same as the tool perspective that classical understanding can shift in a different direction. This is why space is infinite. The tool "you" doesn't change from your perspective. So any change on you forces a mirrored change on the environment caused by interaction. So when you move your locality forces space to become more local, it forces time to flow more like your time, it forces light to behave more like your light. So distant things become more visible and bigger. Motion is one way to keep you coherent as an observer and as a result your enviroment too. There are likely many other things or ways we can change that reveal a different environment with the same classical mechanics.
I would say. Any boundary you draw. This can be a person, a tool or even a random shape. The observer interacts with everything the observer is not and so it becomes a perfect reflection of its environment. So if you cut the observer in half the environment gains the exact amount the observer loses.
Interesting question. Why light though?
If I think of the opposite of gravity I think of the properties gravity has and flip them. Those are:
- it attracts
- it is dark in a light environment
- it is not quantifiable
It's opposite should then:
- repel
- reflect light
- be quantifiable
@rima_medUA I'm following the details every single day. America is very far away so I'm not surprised. People only tend to respond to things on their doorstep. If they are not affected other things become more important. That is where governments should fill the gap. Or people like you.
It's good to know you take some time for yourself because you make great content.
I've had some problems too at times and it can be stress related even though you are convinced you are not stressed at all like I was. My own work on a TOE was playing a role and you do really need to take it slow.
Best wishes Curt!
