Closed Timelike Curves and Singularities

Inference: International Review of Science, 2018
Discovered in 1949 by Kurt Gödel, the homogeneous rotating universe model contains closed timelike curves and therefore allows for travel into the past, accompanied by all its paradoxes.

On The Directional Associated Curves of Timelike Space Curve

2019
In this work, the directional associated curves of timelike space curve in Minkowski 3-space by using q-frame are studied. We investigate quasi normal-binormal direction and donor curves of the timelike curve with q-frame. Finally, some new associated curves are constructed and plotted.

Wormholes and Timelike Curves: Is There Room for the Grandfather Paradox?

1999
Since W.J. van Stockum, K. Godel and F.J. Tipler proposed their solution to the Einsteinian field equations and de Felice et al. discussed Kerr’s ones, the time-machines have turned from fiction to physical objects. Immediately, philosophers of science, such as Earman (1972), Malament (1985) and Horwich (1987), began to analyse them on account of the ...

Darboux Associate Curves of Timelike Curves in E13

In this paper, we introduce k-directional Darboux curves of a given timelike curve alpha lying on a timelike surface in Minkowski 3-space E-1(3) as the integral curves of some vector fields generated by the Darboux frame along the curve. The relationships of such associate curves are given including the relationship of their curvatures.
