Climate experiment
In v3411, the development team at Giant Army patched a major discrepancy in the climate model. Previously, Venus would freeze in certain scenarios that should have turned it into a molten hellscape. This build introduced refined albedo calculations (how much sunlight a planet reflects), making temperatures more realistic. universe sandbox 2 v3411
Use the "Water" and "Atmosphere" tools. v3411 features the best iteration of the Atmospheric Escape simulation. If you give Mars a thick Earth-like atmosphere without a magnetic field, you can watch the solar wind strip it away in real-time. The particle system in v3411 renders this stripping as a comet-like tail trailing behind the planet.
| Phenomenon | Realism in v3411 | Notes | |------------|------------------|-------| | Orbital decay (tides) | Partial | Only Earth-Moon tidal friction modeled | | Roche limit disruption | Yes | Fragments form rings automatically | | Supernova blast wave | Simplified | Pressure wave affects nearby atmospheres | | Radiative heat balance | Moderate | No greenhouse gas absorption spectra | | General relativity | No | No Schwarzschild precession or lensing | Planet collision
Conclusion: Excellent for intuitive understanding of gravity and heat; not suitable for precise mission planning or relativistic astrophysics.
