What values are within a realistic range? It’s a sandbox, so you won’t be constrained by that. What if the heat capacity of the ocean were larger or smaller? What if the heat were transferred less efficiently between land and ocean, or more efficiently between equator and pole? We’ve chosen values that give us realistic behavior for the Earth we live on, but you can see what would happen if it were different. Third you can change the parameters of the model itself. If you give the Earth a less-circular orbit or move it closer to or farther from the Sun, you can see how sensitive we are to being in just the right spot in the solar system. Changing the tilt will affect how extreme the seasons are. Second you can change the orbit of the Earth or its tilt. Change the luminosity of the Sun (but be careful because you might also end up changing its mass, which will affect the orbits of the planets) or add an additional star if you really want to heat things up (or delete the Sun and watch the planet freeze). Universe Sandbox is a physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale. Ex: 2250 km diameter with a density of 9.54. At the start of the accretion disk.if i have an object over 2000 km in diameter, i normally increase its density.those will be my dominants planets (like jupiter in our own solar system) But this depend on the mass of the star. Let’s take a look at the Earth’s climate simulation as an example for the complexity of the experience: There are three ways to affect the climate of the Earth.įirst you can change the solar input. Running the accretion Disk and making the protoplanets grow.
