WebThis paper presents the curvature theory of non-null cylindrical surfaces in Minkowski 3-space. The definition of the line of striction and generator trihedron for cylindrical surfaces in Minkowski 3-space are given. The derivation formulae and WebWe find that the spacelike-squashed AdS3 can be modded out by a suitable discrete subgroup of the isometry group, yielding an extremal black hole solution which avoids closed timelike curves. 1 Introduction It is well known that the low energy limit of string theory can be described by super- gravity theories and higher order curvature terms ... hauptklimazonen

WebDec 9, 2015 · Around ten years ago researcher Dave Bacon, now at Google, showed that a time-travelling quantum computer could quickly solve a group of problems, known as … A closed timelike curve can be created if a series of such light cones are set up so as to loop back on themselves, so it would be possible for an object to move around this loop and return to the same place and time that it started. An object in such an orbit would repeatedly return to the same point in … See more In mathematical physics, a closed timelike curve (CTC) is a world line in a Lorentzian manifold, of a material particle in spacetime, that is "closed", returning to its starting point. This possibility was first discovered by See more When discussing the evolution of a system in general relativity, or more specifically Minkowski space, physicists often refer to a " See more One feature of a CTC is that it opens the possibility of a worldline which is not connected to earlier times, and so the existence of events … See more The chronology violating set is the set of points through which CTCs pass. The boundary of this set is the Cauchy horizon. The Cauchy horizon is generated by closed null geodesics. Associated with each closed null geodesic is a redshift factor describing … See more CTCs appear in locally unobjectionable exact solutions to the Einstein field equation of general relativity, including some of the most important solutions. These include: See more There are two classes of CTCs. We have CTCs contractible to a point (if we no longer insist it has to be future-directed timelike … See more • Causal structure • Causality conditions • Quantum mechanics of time travel • Roman ring See more WebFeb 7, 2024 · TL: DR, a computer that uses Acasual time-travel to send information back in time to complete arbitrarily large computational tasks in zero time, as well as give general pre-cog information.
