What is the grid of the universe and how does it explain the bending of space?

In summary, the conversation discusses the concept of a grid in the universe and whether or not it is a logical idea. There is no physical evidence or experimental support for the existence of a grid in the universe. The idea of a grid is based on using mathematical relationships to measure and understand the universe, but this does not necessarily mean that the universe itself is made up of a grid. The concept of location in space does not necessarily imply the existence of a grid, as it can be measured using different methods and scales. Overall, the conversation concludes that the idea of a grid in the universe is not supported by scientific evidence.

Since everything in the universe can be calculated using 3D grid mathematics, it seems logical that universe would be ON a grid of some sort.

So then what would the grid be, exactly?

After dwelling on this idea for a while, I came to the conclusion that it would have to be space itself, because, it just makes sense. Otherwise, how else could something possibly exist in a specific location OF space?

But said conclusion would logically imply that space is comprised particles (just like the rest of the universe) otherwise how would there be actual points on the grid?

Not only that, but using the distance between the points of space could be used to explain how space could POSSIBLY be "bent" as its predicted to do so in the presence of large amounts of gravity, just by factoring in a varying/closer distance between said space particles proportional to the amount of gravity present.

Thoughts? Agree/disagree?

No, it is not logical. Where exactly is this grid physically? As an experimentalist, I haven't detected it. So you are applying something that hasn't been shown to be true.

I think you are confusing the measuring scale that we use with the actual physical characteristics of space. This is not correct.

I agree w/ zz that this is not logical at all. You're just making it up.

You can apply ANY set of 3D co-ordinates that you like to the universe in order to specify where something is in that grid but unless you specify how you have defined your grid, no one will know what you are talking about.

Weve never proven where gravity physically is either, yet we know it exists, so it could just be on a subatomic level we've yet to access, and yes its a measuring scale but that's the point, the fact that we CAN measure everything using mathematical relationships means that they're an important part of the functioning of our universe, its essentially like saying time doesn't exist in the universe because we use man-made measurements like seconds

And if there were a grid - what sort: Cartesian (rectangular or non-rectangular), cylindrical polar, spherical polar to give but 4.

But we can detect gravity - and feel it. But there's no "grid" that has been detected.

We know that gravity exists because it has measurable experimental consequences. There is no such measurable evidence supporting the idea of some sort of universal grid.

EDIT: and DennisN gets the scoop :smile:

Couldn't one argue that the fact that the idea of a "location" exists in space as evidence? Otherwise, how could anything possibly be located anywhere?

Do you mean evidence of a grid? If you mean this, then:
Sorry - no, not in science. An "idea" is not any evidence whatsoever. Evidence come from experiments. You could have a look at what the "scientific method" means:

Define "location".

  • Introduction to the Scientific Method (University of Rochester)
  • An Introduction to Science (Miami University)

Maybe "idea" was a poor choice of words, but the fact that you and I don't exist on top of/within each other proves that locations exist, does it not?

There is no such thing as "proven" in science.

We have mathematical theory of gravity, which have been verified by experimental evidence. Can you state your "grid" theory at the same level?

Time exist. We use seconds or other unit of time to measure time. However, the UNITS and scale that we use to measure time does NOT define time. I could use any device I like! I can use the propagation of light as time measuring device. Where is the "scale" there?

Again, you are using the units of measurement to define the physical characteristics of what you are trying to measure. This is not correct. You came here to ask. You have been told of your mistakes.

The specific space an object occupies. However, the fact that an object can only occupy so much space implies that space can be quantified, and would theoretically have a limit for how small it can be broken down, like matter, would it not?

That can be measured in principle using radar signals and depends on the motion of the observer making the measurement. There's no grid involved. Nature doesn't provide us with a grid. There are only space-time events that we may represent for our own calculational facility using a grid. The fact that certain objects occupy space is a consequence of quantum mechanics and more specifically Fermi-Dirac statistics, it doesn't imply the existence of some grid.

No it doesn't. There's no logic to that based on your description.

There are proposed ideas of the Planck length scale as being the impetus for the possibility that our space is "grainy". But even with such a proposal that has a lot of theoretical basis, it is STILL a hypothesis that haven't been tested and has no empirical evidence.

Your idea is not even in the same league as this one considering that you are somehow using the fact that "specific space an object can occupy only so much" is not only vague, but also incorrect. Bosons can occupy the SAME space as described in the bose-einstein statistics. Photons have no issues of occupying the same location in space, as many as they want!

How does it imply that?
EDIT: Never mind my question, Zapper already answered right above, and he was also more thorough. I'm getting slow :biggrin:.

I never said objects can't occupy the same space, I said objects can only occupy SO MUCH space, ie why isn't a photon the size of the entire universe, or why does it stop at a specific size?

Couldn't you create a mathematical theory based off the bending of space in the presence of large amounts of gravity? Furthermore, how can space possibly bend without it being comprised of particles?

There is no indication that the fundamental particles of the standard model have a specific size.

That has already been done. It does not involve a grid.

Why should curvature imply particles? That is a very random association.

If you wish to continue this discussion then please post a reference to the peer reviewed journal (see the forum rules) article that you wish to discuss.

But different objects "occupy" different amount of space. An atom occupies a certain amount, a galaxy occupies a different amount. How does that translates into space having grids? Again, this is what I meant by your logic just doesn't make any sense. There is no logic here in how you somehow arrive at your conclusion.

I guess the question lies in whether or not you can bend elementary particles themselves, ie is it possible to bend the matter that is a photon?

Correct me if I'm wrong, but my logic is essentially "what is space but a grid?"

You can bend a steel rod. Do you think you are bending the particles that make it up?

Besides, space doesn't bend anyway. Space-time has geodesics that appear "bent" based on a pure Euclidean straight line but that's hardly the same as saying that space bends.

No, that's my point

As I already said, there is no evidence that elementary particles have a size. It doesn't make any sense to talk about bending something that doesn't have a size.

Since you have yet to post any references it seems that you are engaged in personal speculation, so this thread is closed.
 

FAQ: What is the grid of the universe and how does it explain the bending of space?

1. What is the grid of the universe?

The grid of the universe, also known as the cosmic grid, is a theoretical framework used to map out the structure of the universe. It is a three-dimensional grid made up of lines and nodes that represent the positions of galaxies, stars, and other celestial bodies.

2. How does the grid of the universe explain the bending of space?

The grid of the universe is based on the theory of general relativity, which states that massive objects, such as planets and stars, can bend the fabric of space around them. This bending of space is what causes the grid to appear curved.

3. Is the grid of the universe visible?

No, the grid of the universe is a theoretical construct and is not visible to the naked eye. It is used as a tool to understand the large-scale structure of the universe and is not something that can be physically observed.

4. How does the grid of the universe help us understand the universe?

The grid of the universe allows scientists to map out the positions and movements of galaxies and other celestial bodies, which can help us understand the large-scale structure of the universe. It also helps us to understand the effects of gravity and how it shapes the universe.

5. Can the grid of the universe change or shift over time?

Yes, the grid of the universe is not a fixed structure and can change over time. As the universe expands and evolves, the positions and movements of galaxies and other celestial bodies can shift, causing the grid to change as well.
