I want to start by clarifying what M-theory is, in relation to string theory, just so the context of my answer will be understood. These days, "string theory" encompasses five ten-dimensional superstring theories, the 11-dimensional M-theory of membranes, 26-dimensional bosonic string theory, "supercritical strings" in more than 10 dimensions, and other ...

Our Universe is a larger version of a galactic polar jet. 'Was the universe born spinning?' physicsworld [dot] com/cws/article/news/46688 "The universe was born spinning and continues to do so around a preferred axis" Our Universe spins around a preferred axis because it is a larger version of a galactic polar jet. 'Mysterious Cosmic 'Dark Flow' Tracked ...

In cosmology, when you apply the Einstein equation to the whole [homogeneous and isotropic] universe, you get the Friedman-LemaƮtre-Robertson-Walker (FLRW) equations. These equations dictate how the size of the universe evolves depending on its material content. The different components are characterized by their equations of state, the ratio between ...

I agree with atsby, and would like to say that Dark Matter and Dark Energy are two fundamental concepts of which we know very little about. However I doubt that Dark Matter can be converted to Dark Energy the same way we can convert normal matter to energy, let alone convert Dark Matter to Dark Energy at all. For starters, Dark Matter is the substance ...

Mass and energy are the same thing. If you have a sealed internally reflective box of photons, it will have inertia and a exert a gravitational pull on any other mass/energy that may be around. http://usersguidetotheuniverse.com/?p=2865 That being said, no properties of dark matter or dark energy are known. These terms are used to refer to matter and ...

This is a misconception. Theoretically, Dark Energy is a form of energy which accelerates the expansion of the universe, whereas Dark Matter is thought to be made up of weakly interacting particles (which account for most of the matter in the universe). Dark Matter and Dark Energy have completely different properties, and their names don't imply that they ...

Dark matter are not related in that way. Dark energy is the energy responsible for the accelerating expansion of the universe. Dark matter is a source of gravitation which we couldn't see directly.

Are there another views on what dark matter/energy is? Yes, but you tend not to hear about them because there's a presumption that dark matter consists of particles. This is despite Einstein saying "the energy of the gravitational field shall act gravitatively in the same way as any other kind of energy" in The Foundation of the General Theory of ...
