The Great Filter: An In-Depth Exploration — Josh Universe

I. Introduction

A. Definition of the Great Filter

1. Concept Overview

The Great Filter is a theoretical concept suggesting a stage in the evolutionary process that is extremely difficult for life to surpass. This stage could occur from the emergence of life to the development of advanced civilizations capable of interstellar communication and travel.

• Stage: Any critical phase in the development of life
• Difficulty: Extremely challenging to surpass

2. Relation to the Fermi Paradox

The Great Filter theory is closely related to the Fermi Paradox, which questions why, given the high probability of extraterrestrial civilizations, we have not yet detected any signs of their existence.

• Fermi Paradox: The apparent contradiction between the high probability of extraterrestrial life and the lack of evidence
• Connection: The Great Filter provides a possible explanation for the scarcity of detectable extraterrestrial…
