3. Supernova Simulation

Supernova Simulation

Just based of distances involve it would be quite a few seconds I would imagine; if the matter was traveling at the speed of light (impossible but for arguments sake lets assume) based on distance it would still take a few seconds for matter at edge of the sphere to reach the centre.

E.g the sun (a smaller star than usual for supernova I believe) is 695.7 million meters in radius with speed of light roughly .3 million meters/s (got those of google then made them easier numbers). Now from above I don't believe the whole thing collapses inwards but if it did it would take some time (minutes) based on these numbers.

Other thing is once it detonates then the matter (once again assume speed of light) is moving outwards at a fraction of radius of star per second, so it would appear to go very slowly even at absolute limit.

Take into account that its in fact moving at a fraction of the speed of light (still very impressive) and I imagine you would prob have time to slowly enjoy what was going on at the beginning, before the distances involved become so huge it appears to freeze to the naked eye.

I have no expertise in this area, this is just based on simply thinking about numbers involved, and it gives a pretty amazing idea of whats happening. Personally I would guess it would be like looking a an explosion but at the speed and luxury of a sunset, for example.

I'm really nervous to show this but... I spent 5 years learning how to make games and now I made a survival game about time travel with all of my savings.
