Universe Sandbox 2 v3411 — Quick Guide

3. The "Supernova" Pressure Wave

Prior to v3411, supernovae were visually spectacular but mechanically simple (i.e., a flash and a shockwave). Version 3411 introduced a secondary pressure wave. When a star with sufficient mass collapses:

1. The core rebounds (bounce).
2. A neutrino burst occurs.
3. The v3411 addition: The outer layers are ejected, but they are now affected by radiative cooling as they expand, changing color from blue/white to red as they cool.

Navigation controls (default)

• Rotate scene: left-click + drag.
• Pan: middle-click or right-click + drag (or Alt + left-drag).
• Zoom: mouse wheel.
• Select object: left-click object or use selection box with Shift/drag.
• Frame object (focus): double-click object or use “Frame” button.

Further learning

• Explore built-in tutorials and presets.
• Inspect object property tooltips and in-app documentation.
• Community forums and workshop (if available) host user-made scenarios and mods.

If you want, I can produce:

• A step‑by‑step tutorial for a specific scenario (e.g., planet collision, black hole flyby, climate change), or
• A concise keyboard & controls cheat sheet formatted for printing.

The Significance of Version v3411

Why focus on v3411 specifically? Software archives and changelogs show that v3411 was released during a period of aggressive optimization. Versions immediately prior to this (v3400 series) were notorious for introducing "Heat Simulation 2.0"—a feature that calculated planetary temperature on a per-pixel basis. While beautiful, it melted CPUs. Universe Sandbox 2 v3411 — Quick Guide 3

v3411 is widely regarded by the community as the "Golden Stabilizer." Here is what this specific build brought to the table: The core rebounds (bounce)

Temperature Model

• Stellar flux + internal heat (for gas giants) + tidal heating.
• Albedo modifies absorbed energy.
• Atmosphere layer: Pressure-dependent greenhouse effect.

Object creation & editing

• Add objects: Open Add menu → choose star/planet/moon/asteroid/comet/black hole.
• Edit properties: Select object → use inspector to change mass, radius, density, composition, temperature, spin.
• Velocity & orbit editing: Set position and velocity vectors in inspector or use “Place in orbit” to auto-calculate stable orbits.
• Atmosphere & climate: Enable atmosphere and set composition, pressure, and greenhouse gases; use Climate tool to toggle weather and visualize temperature maps.
• Tectonics: For planets with sufficient resolution, enable tectonics to simulate plate movement and volcanism.
