0th dimension and other dimensions

In summary, the conversation discusses the concept of extra dimensions and their relation to our known 3 dimensions. It is mentioned that extra dimensions are not located within our 3 dimensions and would not overlap with them. The conversation also mentions the existence of a "0th dimension" and the use of mathematics to prove the existence of these dimensions. The website mentioned is deemed misleading and it is stated that the only way to prove the existence of these dimensions is through mathematics.

hi :D
after reading up on 10 dimensions (and how more can be added any time we need them even though they might not exist) i found it interesting how it stated that 5-10 dimensions where located in the well known 3 dimensions we see every day (with the 4th dimension being time).

what i don't understand is that if these are spheres and they overlap so no gap is left between them (if a gap is left that means that these dimensions won't exist everywhere in which case maths which has built up around them will fail) then that means these spheres must overlap with our own 3 dimensions. If they overlap with our 3 dimensions wouldn't that just mean that they are our 3 dimensions and no more.

let me reword it incase it got a little confusing
we know our 3 dimensions quite well... inside our dimensions are other dimensions (spheres if u will which are made up of another 3 or so dimensions). let's say these spheres don't touch each other. does this mean that there are places where only 3 dimensions exist (not taking time into account)?

also how is there a 0th dimension?

thanks

Extra dimensions wouldn't be located "in the well known 3 dimensions we see every day". An extra dimension is by definition a direction that is independent of the others. So there wouldn't be any overlapping spheres.

If you call an extra dimension "0th" or "5th" or even "Dave", is up to you. It just a convention.

so that means the site
http://www.pbs.org/wgbh/nova/elegant/dimensions.html
is misleading

and there's no way to prove these dimensions other than maths rite? so eventually they can be disproven with enough calculations

Why would this site be misleading ?

To us spacetime looks like a continuum. it is only when you probe to much smaller distance-scales that the "granular" structure of space time would become manifest. I am referring to quantized space time here but this also goes for these extra dimensions...

1. What is the 0th dimension?

The 0th dimension is a theoretical concept that refers to a point in space with no length, width, or height. It is often used as a starting point for understanding higher dimensions.

2. How many dimensions are there?

The number of dimensions is a topic of debate among scientists. Some theories suggest that there may be up to 11 dimensions, while others propose an infinite number of dimensions.

3. Can we visualize higher dimensions?

It is difficult for humans to visualize more than three dimensions because our brains are wired to perceive the world in three dimensions. However, mathematicians and physicists use mathematical models and analogies to try to understand higher dimensions.

4. How do dimensions affect our perception of time?

Some theories suggest that time is the fourth dimension, and that our perception of time is influenced by the other dimensions. For example, time slows down in the presence of a strong gravitational force, which is explained by the curvature of space-time in higher dimensions.

5. Are there any practical applications for understanding dimensions?

The study of dimensions has led to important developments in fields such as physics, mathematics, and computer science. It has also helped us understand the structure of the universe and develop technologies such as GPS, which relies on knowledge of space-time dimensions.
