Zeitreisen: Gravitation trifft Quantenphysik (Time Travel: Gravity Meets Quantum Physics)
Rainer Verch
TL;DR
This paper explores the theoretical intersection of quantum physics and general relativity to assess the feasibility of time travel through quantum matter-influenced spacetime geometries.
Contribution
It reviews existing literature on quantum and gravitational models that exclude the possibility of time travel, highlighting current theoretical limitations.
Findings
Literature shows no conclusive evidence for time travel feasibility
Quantum matter influences spacetime geometry but does not enable time travel
Current theories restrict the creation of time-travel scenarios
Abstract
An introduction is given to discussions on the possiblity of fabricating spacetime geometries allowing time-travel scenarios with the help of matter possessing typically quantum features. Those scenarios are considered in the framework of quantum field theory and general relativity. Results established in the literature excluding the possibility of time-travel are presented.
