General Relativity

Robert M. His research interests include general relativity, black holes, and quantum gravity. He is also a science communicator and textbook author. He is the son of the mathematician and statistician Abraham Wald. Wald's parents died in a plane crash when he was three years old.

You bet! There are dozens of superb, up-to-date books on various aspects of relativity theory. Most of these are currently in print and widely available through university libraries and organizations such as Amazon. In addition, several classic books have recently come back into print. It is not an exaggeration to say that there has probably never been a better time to shop around for books on relativity! In what follows I offer a sort of "consumer's guide" which I hope will help readers choose the book or books best suited to their needs.

The meaning of time-reversal and CPT invariances of a theory is discussed both in the context of theories defined on flat spacetime as well as in general relativity. It is argued that quantum gravity cannot be time-reversal or CPT invariant; that an "arrow of time" must be fundamentally built into the theory. However, a weaker form of CPT invariance could still hold, in which case the fundamental "arrow of time" would not show up in the measurements of observers who perform scattering experiments. Consequences of this weaker hypothesis are explored. Robert M. COVID has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.

Einstein said that the most incomprehensible thing about the universe is that it is comprehensible. But was he right? Can the quantum theory of fields and Einstein's general theory of relativity, the two most accurate and successful theories in all of physics, be united into a single quantum theory of gravity? Can quantum and cosmos ever be combined? Though much progress has been made, Hawking and Penrose stress that physicists still have further to go in their quest for a quantum theory of gravity.

General Relativity

Robert Wald

By Robert M. General relativity is the theory of space, time, and gravitation formulated by Einstein in It is often regarded as a very abstruse and difficult theory, partly because the new viewpoint it introduced on the nature of space and time takes some effort to get used to since it goes against some deeply ingrained, intuitive notions, and partly because the mathematics required for a precise formulation of the ideas and equations of general relativity namely, differential geometry is not familiar to most physicists. Although it has been universally acknowledged as being a beautiful theory, the potential relevance of general relativity to the rest of physics has not been universally acknowledged and, indeed, probably for this reason, the subject has lain nearly dormant during much of its history. Strong interest in general relativity began to be revived starting in the late s, particularly by the Princeton group led by John Wheeler and the London group led by Herman Bondi. Although it is difficult to determine the reasons for trends in physics, two developments—relating general relativity to other areas of physics and astronomy—have contributed greatly to the sustained interest in general relativity which has continued since then. The first is the astronomical discovery of highly energetic, compact objects—in particular, quasars and compact X-ray sources.

 Ты не заметил ничего. Ну, может, дошел какой-нибудь слушок. - Мидж, послушай.  - Он засмеялся.

    The articles included in this Volume represent a broad and highly qualified view on the present state of general relativity, quantum gravity, and their cosmological and astrophysical implications.

    Of the general theory of relativity you will be convinced, once you have studied it.
