【题目】Imagine a world with no limits on time, space and gravity(重力). In this 1,humans can move buildings and travel through time with a wave of the hand.Welcome to^{① Doctor Strange's world. Doctor Strange is the latest Marvel comic book hero to be brought to life 2 the big ...
General relativity, which relates the gravitational force to the curvature of space-time, provides a respectable theory of gravity on a larger scale. To be consistent with general relativity, gravity at the quantum level must be carried by a particle, called the graviton, with an intrinsic ...
Relativity - Curved Space-Time, Geometric Gravitation: The singular feature of Einstein’s view of gravity is its geometric nature. (See also geometry: The real world.) Whereas Newton thought that gravity was a force, Einstein showed that gravity arises

Quantum Space-time and Classical Gravity A method has been recently proposed for defining an arbitrary number of\ndifferential calculi over a given noncommutative associative algebra. As an\nexample a version of quantized space-time is considered here. It is found that\nthere i... J Madore,J ...
Yang - Mills gravity is a new theory, consistent with experiments, that brings gravity back to the arena of gauge field theory and quantum mechanics in flat space-time. It provides solutions to long-standing difficulties in physics, such as the incompatibility between Einstein's principle of gene...
While confirmation of gravitational diffusion would suggest that space-time is fundamentally classical. Experiments to detect or bind gravitational diffusion also provide immediate-term prospects for probing the quantumness of gravity, while entanglement-based experiments will only be feasible in the long ...
What is space-time made of? What is the fabric of space-time? John WheelerIt would be better to ask, what is the universe made of? And everything else will come in addition.So, for example, if gravity is a manifestation of the curvature of space-time, and space-time itself is emerg...
The space-time dynamics is derived from the renormalizable higher-derivative quantum gravity developed on the basis of a renormalizable conformal gravity in four dimensions. Based on the linear perturbation theory in the inflationary background, we simulate evolutions of gravitational scalar, vector ...
