Sentence examples for causal setting from inspiring English sources

When these comments are taken altogether, it appears that students place great value on both the broad variety of activities and information that is presented in the course, as well as the ability to learn the information in a relaxed and causal setting, with freedom to express dissenting opinions.

String theory, loop quantum gravity, causal-set theory: these are just a few of the approaches that theorists have taken.

More recently, the causal set approach has also managed to derive the correct value.

That will take a theory of everything, be it string theory, Cortês and Smolin's causal sets, or something else.

For a review of the causal set approach with the relevant references, see Brightwell et al. (2003).

An alternative approach to formulate a fully-fledged quantum theory of gravity attempts to capture the Planck-scale structure of spacetime by constructing it from causal sets.[31] Since these sets must be acyclic, i.e., no element in a causal set can causally precede itself, CTCs are ruled out a priori.

A similar problem faces causal set theory in the form of the 'inverse problem', which roughly amounts to the difficulty of getting continuous manifolds (with their corresponding symmetries) from a fundamentally discrete theory (see Wallden, 2010, for a good recent review of causal sets, including a discussion of this problem, on which progress has also been made).

"Suggests" rather than "implies" because the theorem requires the construction of a bijection between the elements of the causal set and the points of the spacetime manifold to be emulated.

Rovelli and Speziale (2003) have argued that, in fact, the existence of a minimal length does not imply a violation of the Lorentz symmetry (a conclusion seconded by the proponents of the causal set programme).

Other approaches include twistor theory (currently enjoying a revival in conjunction with string theory), Bohmian approaches (Goldstein & Teufel, 2001), causal sets (see Sorkin 2003, in the Other Internet Resources section) in which the universe is described as a set of discrete events along with a stipulation of their causal relations, and other discrete approaches (see Loll, 1998).

Depending on which features of general relativity and quantum theory are accepted unchanged, and on what level changes are introduced, there are numerous other attempts to arrive at a viable theory of quantum gravity, some examples being dynamical triangulations, causal sets, twistor models or the path-integral based models of quantum cosmology.
