No, I mean to complain there are so many things not realistic about Universe Sandbox 2, and it seems things like explosions, climate change, etc are simply parlor tricks tacked onto the game (not a simulator) with no actual emulations of the underlining physics and mechanisms....
For example, to use the exploding/supernova sun again, approximately 8.5 minutes after the sun explodes the light/lighting that hits/(gets cast on) the earth should be DRAMATICALLY different and yet it stays the same as if business as usual...
I'm not nitpicking cosmetic issues...
The earth still is in the same "orbit" post 8.5 minutes after the sun explosions or goes supernova.... Gravity is either instantaneously or travels as fast or faster than speed of light in vacuum.... so how come the earth still travels in same orbit after the sun goes gone?
When the 'heat wave' of the supernova blast finally hits earth it doesn't even knock it out of orbit or influence its trajectory or path!?
This game also does not even attempt to model the effects of relativity on large scales.
