Time run backwards by quantum superoscillation
Yakir Aharonov, Avshalom Elitzur
The concept of time has undergone several twists in modern physics. Special and general relativity have shown that time is dilated due to high velocities or strong gravitational force. Quantum mechanics has rendered time subject to uncertainty alongside with energy. No effect, however, is known where time slows down below zero, to the point of becoming negative. We now demonstrate such a case. A gravitational shell is put in a quantum superposition of radii, such that the gravitational potential within it is also superposed. Consequently, time dilation becomes similarly superposed. By using quantum superselection, we select a case where time slows down below zero; namely, going backwards. A process within this shell, where entropy should increase, is therefore expected to be found wih entropygoing back dows. Surprisingly, this effect does not depend on the system's magnitude, as long as its mass is not large enough to change the gravitational field.
Inertia-Gravity, Mach's Principle, and Entropy Increase.
Avshalom Elitzur
An observer in outer space, at rest with respect to the universe, undergoes acceleration. By Mach's principle, it can equally be the universe that accelerates, exerting a gravitational pull oh her which she resists. In order for this effect to precisely mimic the ordinary one, the universe's acceleration must have begun billions of years in the past, gradually increasing in the form of a gravitational wave precisely converging on the observer. This result present perfect entropy decrease, suggesting hitherto unnoticed relations between general relativity and thermodynamics.

The concept of time has undergone several twists in modern physics. Special and general relativity have shown that time can be dilated under high velocities or strong gravitational force. Quantum mechanics has rendered time subject to uncertainty together with energy. No effect, however, is known where time slows down below zero, to the point of becoming negative. In this paper, we demonstrate such a case.
The outline of this paper is as follows. First, we introduce the Two State-Vector Formalism of quantum mechanics, (TSVF). Second, we briefly introduce the notion of superoscillation. We then proceed to propose a Gedanken experiment. A gravitational shell is put in a quantum superposition of radii, such that the gravitational potential within this shell is also superposed.
