# Can someone explain to me exactly what is meant by vanishing dimensions theory?

• L.J.Tibbs
In summary, the conversation is about the concept of vanishing dimensions and its different theories. One theory suggests that the universe was initially in two dimensions and then warped into four dimensions. Another theory proposes that the universe started with 10 dimensions and eventually split into four and six dimensions. The second theory, also known as the string theory or M-theory, is discussed in the book "Hyperspace" by Michio Kaku.

I really like it, but haven't seen any good, simple descriptions of it! Is there any place to get just the overall gist of it?

Vanishing dimensions is basically the theory that the universe was earlier in just two dimensions. At some point in the past, these dimensions warped over, and became four. How this happens is yet unclear, but mathematics will have to be really crazy to get that result.

This is where the above explanation is given.

Yet another theory states that when the universe started out, it had 10 dimensions, and one more 'super' dimension (Edward Witten's hypothesis). However, after the big bang some kind of rift tore the ten dimensional universe into one of four, and one of six (plus one) dimensions. The 4 dimensional universe kept expanding, but the 6 dimensional one collapsed tinier and tinier, effectively 'vanishing'. I'm more convinced with the second, which is also known as the string theory (now, the M-theory), you can find out about it in 'Hyperspace' by Michio Kaku.

## 1. What is vanishing dimensions theory?

Vanishing dimensions theory, also known as the "vanishing dimensions hypothesis," is a concept in theoretical physics that suggests that the number of observable dimensions in our universe may be greater than the 3 spatial dimensions (length, width, and height) and the 1 time dimension that we are familiar with. It proposes that these additional dimensions may have existed in the early stages of the universe but gradually disappeared as the universe expanded and cooled.

## 2. How does vanishing dimensions theory relate to string theory?

Vanishing dimensions theory is closely related to string theory, which is a theoretical framework that attempts to unify all known forces and particles in the universe. In string theory, these extra dimensions are described as tiny, curled-up spaces that cannot be observed directly. Vanishing dimensions theory suggests that these dimensions may have disappeared over time, causing the universe to appear as 3-dimensional space with 1-dimensional time.

## 3. What evidence supports vanishing dimensions theory?

Currently, there is no direct evidence to support vanishing dimensions theory. However, some scientists believe that this theory could potentially explain some of the mysteries in physics, such as the hierarchy problem (why the forces of nature have vastly different strengths) and the unification of gravity with the other fundamental forces.

## 4. How does vanishing dimensions theory impact our understanding of the universe?

If vanishing dimensions theory is proven to be true, it would drastically change our understanding of the universe and the laws of physics. It would suggest that the universe is far more complex and mysterious than we currently realize, with hidden dimensions that could have a significant impact on the behavior of matter and energy.

## 5. Can vanishing dimensions theory be tested?

At this time, there is no known way to directly test vanishing dimensions theory. However, some scientists are working on experiments and observations that may provide evidence for or against the existence of extra dimensions. These include experiments at the Large Hadron Collider and observations of gravitational waves, which could potentially reveal the effects of these hidden dimensions on the behavior of particles and forces in the universe.
