Event Horizon

Event Horizon for Obsidian

Install Event Horizon from the Community Themes

Event Horizon is a high-contrast, deep-space dark theme engineered for research, writing, and complex knowledge graphing. Built around dark energy palettes, spectral line highlights, and distraction-free focus modes, it turns your Obsidian vault into an interactive star system.

📸 Visual Overview

Cosmic Constellation Graph View

Graph nodes render with high-luminance glowing cores, cyan active connection vectors, and distinct violet fills for unresolved nodes.

Semantic Cosmic Callouts & LaTeX Support

Pre-built semantic callouts ([!singularity], [!observation], [!hypothesis], [!quantum]) featuring spectral aura glows alongside crisp MathJax/KaTeX display equation framing.

✨ Key Features

• 🌌 Deep Space Palette: Pure void blacks (#0b0d12) combined with nebular slate workspace tiles to reduce eye strain during extended work sessions.
• 💫 Graph View Constellation Map: Graph nodes render with high-luminance glowing cores, cyan active connection vectors, and violet unresolved links.
• 🧘 Zen Focus Mode: Sidebar controls, ribbons, and header clutter auto-fade while active typing is detected, keeping your editor isolated like a quiet void.
• 🌌 Cosmic Callouts: Pre-built semantic callout blocks for [!observation], [!hypothesis], [!singularity], and [!quantum].
• 📐 Enhanced LaTeX & Math Styling: Formatted MathJax/KaTeX display equations featuring glowing left accent borders and subtle void framing.

🎨 Cosmic Callout Syntax

> [!observation] Spectral Shift
> Observed redshift across the outward node cluster.

> [!hypothesis] Energy Coupling
> Entanglement entropy scales linearly with horizon boundary area.

> [!singularity] Irreversible Collapse
> Core notes beyond this line become dense knowledge primitives.

> [!quantum] Superposition
> This state holds multiple contradictory interpretations simultaneously.
