![]() ![]() Even the once scorching hot Sahara is now beginning to be covered in iceġ44 days after sun-out, surface temp -3.47C, the whole of Africa is now covered in iceĢ35 days after sun-out, with the temperature -10.6C, bodies of water now begin to freeze from the north, creating an expanding ice cap that will soon cover the northern hemisphere and within months, the world. Land masses in the northern hemisphere are now covered in ice. Ice begins to form in the northern landmassesġ05 days after sun-out, surface temp has dropped to -0.0203C and still dropping. With no parent star to hold the planets in orbit, each body drifts away from orbitġ3 days after sun-out, surface temp drops further to 10C. 5 days after the Sun goes out, surface temperature sits at 14.1C ![]() Somehow, the simulation has become erroneous since it still simulates daylight (which is not possible since there is no Sun). then suddenly, the sun just vanishes (I deleted it lol) The game depicts the orbits of the different bodies around the sun. This scenario aims to simulate what happens if one day, the sun just vanishes (well maybe it's not very realistic, as a star's collapse usually comes with novae, and our Sun is not that old yet to collapse) from the system.įirst of all, here's a shot of the solar system we know. Will Earth, or any othet planet, be habitable after an asteroid impact (taking radiation in consideration)? Given that it took 10 years (in the game) for surface temperatures to go back to normal, was the simulation necessarily accurate?ĥ. Can an asteroid impact that big cause a shift in the Earth's axial tilt?Ĥ. What are the chances of a Ceres-like object impacting Earth?ģ. What caused the sudden high temperatures that dried up the bodies of water?Ģ. Here are my questions regarding the first scenario.ġ. Year 10, remains of Africa and Europe (game depicts city lights on the dark side of Europe, so I guess there's people again? lol) Year 10, from another angle we see the remains of America which is heavily flooded Year 10, still massive icing which I found to be seasonal (it recedes midyear) which might be due to the change in the Earth's tilt. ![]() Massive icing has occurred on some continent though in this screenshot I can't really tell Year 9, surface temp has dropped down to 31C. There is evidence of clouds and weather systems again although surface temp is still at 134C Year 8, water has fully covered all the major bodies again. Year 7, first signs of water appear in different parts: Gulf of Mexico, small parts of the Atlantic, impact crater. Here are the remnants of the Indian ocean, SEA and Antarctica. There is evidence of a shift in Earth's axial tilt. At this moment, temperature shot up to 590C and is still increasingĭays after the impact, the whole planet is engulfed in seemingly really hot matter (molten rock maybe?) No idea why it turned blue, anyway, it's getting really close to Earth, casting its shadow on SE Asia Surface temperature sitting at a nice 14.8C ![]() Year 0, here we see Earth and a nice view of the Pacific ocean. I was trying to get a good feel on how it would look like if a Ceres-sized object impacted Earth. *All scenarios are simulated in Universe Sandbox 2.* Due to a really educational insights people have posted here, I've expanded the thread to include other doomsday scenarios as well. Or so that it automatically iterates through a few passes to determine the burn times and calculates pitch rates based on start/end angles.I started this thread with the aim to get feedback from the community regarding the chances of survival and inhabiting and repopulating the Earth after an asteroid impact. Maybe it could be rewritten so that the angle is a function of the fraction of stage fuel consumed, rather than time. For example if you immediately pitch over from 80º to 45º at the start of stage 2, you could program in stage 2.1 with a very fast pitch rate using the first 5% of stage 2's fuel and then stage 2.2 with zero pitch rate using the remaining 95% of stage 2's fuel.Īdmittedly a bit roundabout compared to setting angles directly, but since the burn time per stage is unknown at the start of the simulation it's not easy to program stages by start/end angle. If the pitch rate is not continuous, you could program it in as an additional stage. If you have a mostly constant pitch rate during a stage, you would get it from the start and end angle and the stage time (which is itself an output, based on fuel consumption and varying Isp, so some iteration is required). ![]()
