Описание: This collectionof stories touches upon many genres: Normed Trek is a clever and wittyAlice-in-Wonderland-type narrative set in the realm of mathematical analysis, The Cantor Trilogy is a dystopia about theconsequences of relying upon computer-based mathematical proofs, InSearch of Future Time bears the flavor of Tales from Arabian Nights set inthe future, and – last but not least - Murderon the Einstein Express is a short, non-technical primer on probabilitiesand modern classical physics, disguised as a detective story.Written primarily for an audience with some background or a stronginterest in mathematics, physics and computer science (in particular artificial intelligence), these stories explore theboundaries between science and fiction in a refreshingly unconventional fashion.In the Afterthoughts the author provides some further insights and annotations.

This work investigates the theoretical and cosmological implications of modifying Einstein's theory of general relativity. It explores two classes of modifications to gravity: those in which the graviton is given a small mass, and those in which Lorentz invariance is spontaneously broken. It elucidates the nature of cosmological perturbations in theories of massive bimetric gravity, including a potentially deadly instability. Theories of gravity beyond general relativity could explain why the expansion of the Universe is accelerating, obviating the need for a dark energy, and can also affect the evolution of the early Universe. Next, it investigates the nature of spacetime in massive gravity theories that contain two different spacetime metrics. Lastly, the strongest constraints to date are placed on the size of Lorentz-violating effects in the gravity sector during inflation.
