Update 30

Spin apart planets with the Force Spin tool and discover the destructive potential of the newly simulated centrifugal force. We’ve also improved same-sized object collisions so you can launch the Earth at itself and watch the shockwaves heat and fragment both planets on impact.

Centrifugal Force

Planets will fragment at very high rotational speeds as the centrifugal force overwhelms the gravity holding them together. Learn more: Home > Guides > Centrifugal Destruction

Same-Size Object Collision Improvements

Colliding two objects of similar size now causes heating and fragmentation on both objects. See the destruction yourself: Home > Open > Earth & Earth Collision

Move Oceans

Centrifugal force now pushes water on fast-spinning objects toward the object’s equator.

Force Spin Tool

Change an object’s rotational speed, poles, and equator with the new Force Spin tool. Check it out in: Tools > Force > Spin

More Highlights

  • Rotation and speed of objects after collisions are now more accurately conserved, decreasing when mass is gained and increasing when mass is lost
Before
After
  • The habitable zone changes to use the properties of the object you have selected to show its optimal habitable distance
  • You can now change the Number of Atmosphere Layers an object has and create Venus-like planets
  • The Hubble Space Telescope has been added to Universe Sandbox
  • We’ve corrected the orientations of the James Webb Space Telescope (now facing away from the Sun) and Parker Solar Probe (now facing toward the Sun)
