# Revised Theory of Tachyons in General Relativity

## TL;DR

This paper revises the theory of tachyons within general relativity by modifying the Energy-Momentum Tensor, resulting in significant theoretical implications and a potential explanation for Dark Energy.

## Contribution

It introduces a sign change in the tachyon Energy-Momentum Tensor, offering new insights into their role in cosmology and Dark Energy.

## Key findings

- Theoretical consequences of the sign change are explored.
- A plausible explanation for Dark Energy is proposed.
- New predictions for tachyon behavior in cosmology are suggested.

## Abstract

A minus sign is inserted, for good reason, into the formula for the Energy-Momentum Tensor for tachyons. This leads to remarkable theoretical consequences and a plausible explanation for the phenomenon called Dark Energy in the cosmos.
