Dear PF Forum,
I have no background in physics

2. And this iron ball, Earth mass, barely chandrasekar (did I type the name correctly) mass will become black hole?
3. If number 2 is true, how long will it take for this iron ball to become black hole.
4. And black hole will evaporate through Hawking Radiation (to photon?). Is this true that an Earth size black hole to evaporate completely will takes 2^10^26 years?
5. And finally in simple answer, what is quantum tunnel?

1. If an Earth size object is left alone (assuming the Sun won't swallow it 2 billions year later). In 101500all of it atoms, oxygen (majority abundant in earth, right), silicon, nitrogen (abundant in atmosphere, right), in short every atom even the heavier ones, uranium, radium, etc... they will become iron?Similarly, if the black dwarfs and planets and the like don't evaporate and their protons don't decay, they may quantum-tunnel into becoming solid iron - as I already mentioned, this takes about 101500 years. And then, if this iron doesn't evaporate and nothing else happens, these balls of iron will eventually quantum-tunnel into becoming black holes, which then Hawking-radiate away. This would take about 10100000000000000000000000000 years - that's 26 zeros.
