Is quantum gravity real?
There are a number of proposed quantum gravity theories. Currently, there is still no complete and consistent quantum theory of gravity, and the candidate models still need to overcome major formal and conceptual problems.
What is quantum holonomy theory?
Our theory — we call it quantum holonomy theory — is based on an elementary algebra, that essentially encodes how stuff is moved around in a three-dimensional space.
Is the theory of gravity complete?
This theory is highly accurate in its predictions regarding everyday phenomena. However, high precision measurements of motions in the solar system and in binary pulsars, the structure of black holes, and the expansion of the universe can only be fully understood in terms of a relativistic theory of gravitation.
What are the 11 dimensions in M-theory?
M-theory is described at low energies by an effective theory called 11-dimensional supergravity. This theory has membrane and 5-branes as solitons, but no strings….SUPERSTRINGS! M-theory.
| M-theory on circle | IIA in 10 dimensions |
|---|---|
| Unwrapped membrane | D2-brane |
| Wrap fivebrane on circle | D4-brane |
| Unwrapped fivebrane | NS fivebrane |
What is the 11th dimension called?
The 11th dimension is a characteristic of spacetime that has been proposed as a possible answer to questions that arise in Superstring Theory, which involves the existence of 9 dimensions of space and 1 dimension of time.
Why is dimension 11?
Scientists do not believe there can exist more than 11 dimensions because conditions become unstable and particles naturally collapse back down into 10 or 11 dimensions. The 12th dimension, for example, introduces a second time. While strings can only vibrate in 10 dimensions, membranes can exist at 11 dimensions.
