These simulations feature our Solar System as a whole, including some or all of the moons, dwarf planets, and/or smaller Solar System objects.įictional simulations are inspired by situations or worlds that are described in books, TV, movies, other video-games, etc. The entire database can be accessed via the Add tool. These simulations feature a selection of exoplanet systems included in the Universe Sandbox database. These simulations feature the planets of the Solar System and their moons. These simulations illustrate each of the constellation sets available. This includes planetary flybys by spacecraft, solar eclipses, famous comets, etc. Historical simulations are centered around an important event that has occurred in the world of astronomy. the Moon orbited much closer to the Earth?. Physics simulations demonstrate several of the physics simulation features in Universe Sandbox. Each simulation in this category is editable using the pencil icon that appears when you hover over the simulation name. These simulations involve objects randomly placed in orbit around another object: like Earth surrounded by hundreds of moons, random planetary systems, or sixty stars in a chaotic swarm. See the Explode tool for ways to create your own explosions. These simulations show various simulated explosions: the Sun exploding in a supernova, the Moon exploding near the Earth, or the Earth exploding in real-time. Simulations in this category involve planets, moons, asteroids, stars, and black holes crashing into each other. Check in on a live view of the Solar System, find out whether all of the planets can actually fit between the Earth and the Moon, see the nearest 400 stars, and watch the chaos unfold as 200 moons try to orbit around the Earth. You can also check out the climate tutorials right in Universe Sandbox ²: Home -> Main -> Activities.This category includes some of the key scenarios included in Universe Sandbox, to give you a broad sample of the abilities of the simulation. But simulating them in Universe Sandbox ² can help you gain a more intuitive understanding of what is possible for the future of Earth’s climate.Ĭheck out this blog post by Naomi, Universe Sandbox ²’s climate scientist, to learn more about how we simulate climate: Climate in Universe Sandbox ². Below is a simulation of RCP6 through 2100. To see how the different scenarios play out, you can graph Earth’s temperature over the course of several decades. This has the effect of increasing the greenhouse effect and ultimately increases the average temperature of the planet. The change in net radiative energy balance is also specified by the scenarios, and we put that right into our energy balance as a decrease in outgoing infrared energy. Once enabled, the pathway’s concentration level will be tied to the simulation year. Click the (+) icon to select one of the other 4 scenarios. In Universe Sandbox ², you can enable RCPs by selecting the Climate tab in Earth’s properties and toggling “Select an RCP Scenario.” The default is RCP 8 5. (This is simplified for the sake of this introduction you can learn more here.) One assumes a peak in greenhouse gases in the next decade, while another assumes that there will never be stabilization. Not only do the scenarios project different outcomes for concentrations, but, importantly, they each follow a unique trajectory based on a range of possible socio-economic changes. To stabilize concentrations, decreases in emissions are required, because even when emissions are lowered, CO₂ hangs around in the atmosphere for a long time. ![]() Each RCP makes different assumptions about how and when these factors might change. Policies, land use, global population, our attitudes toward production and consumption - these can all have a huge impact on greenhouse gas emissions. There are many factors we can consider when looking at what changes will affect emissions. CO₂ emissions and associated concentrations generated from the RCP Database.
