Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Unsolved conjectures in Mathematical General Relativity
数学 广义相对论 未解 猜想
2023/5/5
I will review the recent progress, including my own contribution, in addressing the Kerr Stability Conjecture (克尔时空稳定性猜想）and the Strong Cosmic Censorship Hypothesis (强宇宙监督假设)，both of which are among t...

Scientists ditch approximations,begin modeling universe with Einstein’s full theory of General Relativity
Scientists ditch approximations modeling universe Einstein’s full theory General Relativity
2016/7/4
Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of...
Relativity,the Open Future,and the Passage of Time
temporal passage becoming relativity A Theory B Theory the open future branching spacetimes
2016/6/15
Is the objective passage of time compatible with relativistic physics? There are two easy routes to an affirmative answer: (1) provide a deflationary analysis of passage compatible with the block univ...
Relativity as Support for Presentism:A Modest Evidential Argument
Presentism eternalism special relativity Euclidean space-time
2016/6/15
Presentism is roughly the view that only the present exists. This view requires an absolute simultaneity relation. The special theory of relativity, however, is highly successful and does not account ...
Why Einstein did not believe that General Relativity geometrizes gravity
General Relativity Einstein Geometrization Unification Inertia Gravity Geodesic Equation Meyerson
2016/6/14
I argue that, contrary to folklore, Einstein never really cared for geometrizing the gravitational or (subsequently) the electromagnetic field; indeed, he thought that the very statement that General ...
Matter or geometry as fundamental in relativity theory:How not to teach special relativity
relativity spacetime ontology constructivism
2016/6/13
In this paper, I review a number of interpretational frameworks for relativistic phenomena like length contraction and relativity of simultaneity. Of central focus is the book Physical Relativity by H...
Protective measurements and relativity of worlds
wave function many-worlds interpretation protective measurements relative facts interpretation
2016/6/13
It is a fundamental and widely accepted assumption that a measurement result exists universally, and in particular, it exists for every observer, independently of whether the observer makes the measur...
Space-time,relativity and quantum mechanics:In search of a deeper connection
spacetime translation invariance relativistic invariance linear quantum evolution free Schrodinger equation
2016/6/13
It has been shown that the Lorentz transformations in special relativity can be derived in terms of the principle of relativity and certain properties of space and time such as homogeneity. In this pa...
Relativity,Quantum Entanglement,Counterfactuals,and Causation
Causation Counterfactuals Relativity Entanglement
2016/6/13
We investigate whether standard counterfactual analyses of causation (CACs) imply that the outcomes of space-like separated measurements on entangled particles are causally related. While it has somet...
Formal statement of the special principle of relativity
relativity principle covariance operational
2016/6/13
While there is a longstanding discussion about the interpretation of the extended, general principle of relativity, there seems to be a consensus that the special principle of relativity is absolutely...
Similarity,Topology,and Physical Significance in Relativity Theory
similarity topology physical significance general relativity models contextualism
2016/6/13
Stephen Hawking, among others, has proposed that the topological stability of a property of spacetime is a necessary condition for it to be physically significant. What counts as stable, however, depe...
Time in the theory of relativity:on natural clocks,proper time,the clock hypothesis,and all that
relativity Einstein natural clock atomic clock proper time clock hyothesis
2016/6/12
When addressing the notion of proper time in the theory of relativity, it is usually taken for granted that the time read by an accelerated clock is given by the Minkowski proper time. However, there ...
