It's just the long lead time between life getting started and multicellular organisms evolving that makes it seem like A spectra stars wouldn't allow higher life forms a chance to evolve. I figured that life on it would still be microorganisms.Īlso, there are hints that life actually started very early, within several hundred million years after the Earth formed (or at least after the late heavy bombardment anyway). Alternatively, it could be an Europa analog.įor the planet with an A5 V spectral type sun, it seemed to have even less water than Mars since the water present were in various big lakes. If you want maybe a few photos or videos, you can show your son some gameplay on both and see which one he likes.For abiogenesis (or maybe you're mixing it with panspermia?), if you're talking about the cold (more like frozen, unless the liquid is something other than water) terran planet, theres the problem of what form or how life would evolve on such a cold world. You can even experiment with black holes.

You can heat planets up, change their speed. Space engine you can explore different planets and see what happens, My opinion? Universe sandbox is your go to if your son wants to experiment, You can even give the moon a ring like saturn.

You can't exactly make the planets clash like Universe Sandbox. Space Engine is more like a simulation of the universe. However it only require a gigabyte of storage, if your downloading from steam that is. While this may seem fun, it does lag and take up alot of graphics. In Universe sandbox, one of the first tutorials is seeing how andromeda galaxy collides with the milky way. If you want an interactive version of space where you can see what would happen if earth orbited mercury, or if halleys comet were to hit a planet like jupiter, or even see what would happen if centauri B was the sun of our solar system, Universe sandbox is your go to.
