The oxidation reaction excites electrons in the material that emit light as they relax to lower energy levels with the frequency and thus colour of the light emitted depending on the energy gap between the excited and ground states. Carbon for example, emits yellow light usually when the flame isn't very hot.

Depends what the damn thing is made off. Since it exploded it is likely mostly rock rather than metal and will have a lower density. 2 tonnes per m3 seems reasonable to me.

I intend to have body parts replaced with cybernetics when they wear out. We already replace hips, knees, elbows etc with quite crude prosthetics and in 50 years time, when I'll be needing them, I expect them to have advanced to the point where they are superior to organic ones.

The only really irreplaceable thing in the body is the brain. So long as I don't have a degenerative brain disorder later on, it follows that eventually most or all of the organic body will be replaced with artificial parts, simply as a matter of iteration. Blood can be replaced with artificial blood cells that are currently being developed. Realistically I expect artificial blood to be available around 2025. Some say sooner, some later but the 20's promise to be a decade full of advances.

I'm being optimistic but i don't think i'm being unrealistic. Demand will drive innovation and invention. Right now we stand on the cusp of being able to make clinical immorality a genuine prospect, that said I doubt the majority of the world will benefit from such things as they will only be available to well off upper-middle class people.

Some say we will never achieve effective immorality or mind uploading or endless life extension. To them, I would point them in the direction of 'The fable of the Dragon Tyrant' story.

>They die. Most likely in under 3 days.

Moar like 3 hours if they are n00born.
