The Pseudoscience of Time Travel

TL;DR

The paper argues that the common assumption supporting time travel into the past is logically flawed, rendering the concept unscientific and pseudoscientific despite its consistency with general relativity.

Contribution

It critically analyzes the assumptions behind past-directed time travel and demonstrates their logical inconsistency, challenging its scientific validity.

Findings

Zero change to the past does not imply zero change to the present.

The assumption supporting time travel into the past is logically inconsistent.

Time travel into the past is unscientific and pseudoscientific.

Abstract

Because closed timelike curves are consistent with general relativity, many have asserted that time travel into the past is physically possible if not technologically infeasible. However, the possibility of time travel into the past rests on the unstated and false assumption that zero change to the past implies zero change to the present. I show that this assumption is logically inconsistent; as such, it renders time travel into the past both unscientific and pseudoscientific.
