tachyon-communication

The use of tachyons, hypothetical faster-than-light particles, as a means to send messages backward through time.

7 chapters across 1 book

Preamble

The chapter 'Preamble' introduces a dual timeline narrative set in 1998 and 1962, highlighting Earth's ecological crisis in the future and the scientific efforts in the past to communicate across time. It focuses on a tachyon scientist in England trying to warn the past about impending disaster, while in 1962, Gordon Bernstein, a young researcher, detects anomalous signals that lead him to uncover the reality of time manipulation.

Chapter 9

In this chapter, Gregory Markham visits the Cavendish Laboratory to discuss an experimental project involving tachyons and the possibility of sending messages into the past. The conversation reveals the scientific basis, potential paradoxes, and political challenges surrounding the experiment, including funding priorities amid global crises and skepticism from government officials. The chapter highlights the tension between urgent present-day emergencies and the speculative hope that influencing the past might prevent future disasters.

Chapter 10

In this chapter, Marjorie hosts a meticulously planned dinner party where social dynamics and scientific discussions intertwine. The guests include Heather and James, the Markhams, and John Renfrew, who is involved in a groundbreaking tachyon experiment. Through conversations, the chapter explores the implications of faster-than-light particles on physics and time, highlighting the challenges and excitement of pioneering scientific research amid social and institutional pressures.

Chapter 20

In this chapter, Gregory Markham, Renfrew, and Ian Peterson discuss the challenges and implications of sending and receiving tachyon signals to the past, including the risk of paradoxes. They analyze anomalous noise detected in their experiments, hypothesizing it may originate from tachyons emitted by microuniverses—small closed-off universes within our own—suggesting the existence of layered realities and complex cosmic structures. The chapter explores the tension between scientific caution and curiosity as the team grapples with the unknown consequences of their groundbreaking work.

Chapter 28

In this chapter, Ian Peterson arrives unexpectedly at the laboratory to insist that Gregory Markham accompany him to the United States to support Renfrew's experimental work involving tachyons and potential time communication. The discussion reveals the scientific and philosophical challenges of the experiment, including the implications of dark matter, cosmological theories, and the paradoxes of free will in causal loops. Cathy Wickham and Markham debate the theoretical underpinnings of their work, while Peterson's administrative authority and interest in the physics underscore the tension between scientific inquiry and bureaucratic control.

Chapter 44

In this chapter, Gordon and Claudia Zinnes discuss the intermittent loss of an anomalous tachyon-related signal linked to the constellation Hercules, leading Gordon to analyze the timing and visibility of Hercules to optimize signal detection. Gordon balances his demanding academic responsibilities with his experimental work, while tensions arise over scientific credit and publication. The chapter also explores Gordon's reflections on the nature of scientific discovery, the challenges of interpreting ambiguous data, and his personal struggles amid political turmoil and professional pressures.

Chapter 50

In this chapter, John Renfrew works tirelessly to maintain a tachyon transmitter aimed at the past, attempting to send and receive messages across time despite technical difficulties and his deteriorating health. He intercepts a mysterious signal from the future (year 2349), which rekindles a faint hope of communication beyond his isolated present. Ultimately, Renfrew accepts the loss of control over causality and turns his attention to the immediate world and relationships around him, finding a bittersweet sense of freedom.
