A Questions about black holes.

    1. As protons will eventually decay, will objects made with protons orbiting black holes that are time-dilated remains?
    2. What happened at someone's perspective if he/she fell into a super massive black holes? Will he/she be free instantly? (Time dilation)
    3. What happens after the last black holes evaporated away? Will this be the final and infinite dark age where there's nothing? Or matter eventually warped (quantum tunneling) into a new place and explode as the new Big Bang again?

    1) No one is sure if protons decay or not, otherwise, yes. Objects in orbit around black holes will decay slower.
    2) If you are falling into the black hole, everything will be normal, you are the reference frame. From your perspective, it's the rest of the universe that'll be acting weird (it'll be accelerating and going by very quickly.) You'll float gently past the event horizon, since it's way way out there, but as you get close to the singularity, the tidal forces will tear you apart at the atomic level.
    3) Unknown, according to the laws of physics as we understand them right now, that'll be the end of the universe. Heat death.

    1. Proton decay is a theoretical but unconfirmed possibility. Despite a number of tests proton decay has never been detected to date suggesting a half life in excess of 10^33 years which exceeds the age of the universe by about 24 orders of magnitude and rivals the life expectancy of most black holes. Furthermore, time dilation much beyond the event horizon of black holes is pretty trivial. Once matter crosses the EH any protons are doomed to be folded, spindled and mutilated [i.e., ripped to quarks]

    2. An observer free falling into a black never notices anything unusual. They may as well have lept into the grand canyon on earth. By their clocks they pass from just beyond the EH to the afterlife in a relatively brief period of time.

    3. Unknown. Some of the larger black holes are expected to be around for another googol or so years. Our physics models are far too primitive to permit even a wild guess as to what might happen that far into the future.
