How Do Black Holes Affect Time and the Fate of the Universe?

In summary: Consider that a googol years is vastly longer than the time it takes for all the black holes to evaporate by Hawking radiation and you get some idea of how long we have to improve our understanding of the universe.In summary, the discussion covers questions about proton decay, time dilation near black holes, and the fate of the universe after all black holes have evaporated. There is uncertainty surrounding all of these topics, but it is believed that objects in orbit around black holes will decay slower, an observer falling into a black hole will experience normal time, and the end of the universe may be marked by heat death or potentially a new Big Bang.

Questions.
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.

1. What is a black hole?

A black hole is a region in space where the gravitational pull is so strong that nothing, including light, can escape from it. This is caused by a concentration of mass in a small space, which warps the fabric of space-time.

2. How are black holes formed?

Black holes can be formed through a few different processes, such as the collapse of a massive star or the merging of two smaller black holes. These processes result in a singularity, a point of infinite density and gravity, at the center of the black hole.

3. Do black holes suck everything in?

Contrary to popular belief, black holes do not suck everything in. They only have a strong gravitational pull within a certain distance called the event horizon. Anything outside of this boundary would not be affected by the black hole's gravity.

4. Can anything escape from a black hole?

According to our current understanding of physics, nothing can escape from a black hole once it has passed the event horizon. However, some theories suggest that information may be able to escape from a black hole in the form of Hawking radiation.

5. Are there different types of black holes?

Yes, there are three main types of black holes: stellar, intermediate, and supermassive. Stellar black holes are formed from the collapse of a massive star, intermediate black holes are believed to be the result of multiple smaller black holes merging, and supermassive black holes are found at the center of most galaxies, including our own Milky Way.
