Potentiality??
Time scales are beyond your average hominid too understand...why not Black Holes Phil?

Just a guess here.

Evaporation is really only an issue for small black holes.

A black hole with the mass of the sun would take about 2.098 × 1067 years to evaporate so how long would it take it take if it has the mass of the universe?

First explain how the mass of the universe would end up in one black hole. Before you do, please read the second half of my other post. As far as the length of time it would take, doesn't matter since we are talking of a time scale somewhere in the neighborhood of 10100 years.

I'm not understanding your question Kichi. Black Holes are a prediction of General Relativity and they are understood.

If those two atoms were in an otherwise empty universe eventually gravitational attraction would bring them together.

How long it would take is another matter but it would happen.

Now think of that universe containing 190 billion supermassive black holes(give or take a couple of billion), it will happen. And before they have time to evaporate.

And even so what of the particles emitted? they will just be absorbed by other blackholes. Where else are they going to go?

It is not a question Phil but a guess.

As you have clearly stated the time scale is 100x100 light years for any "black Hole" to consume it's galaxy. What I am pointing out is that people have great difficulty in assimilating 50 year weather patterns let alone 100x100 time spans.

for you and me this is not an issue for others it is. They are collectively unable to make it to the next decade let alone further. Such is the limitations of the human mind.

This stops right here until you show with the proper maths that two Hydrogen atoms would do what you claim. Maybe it would have been easier if you had understood the example as is instead of trying to change it. Tell you what, you might want to read From Eternity To Here by Sean Carroll before you continue arguing nonsense.

Phil don't you DARE get all uppity and impatient on me!!

No one is saying ANYTHING is "gospel"

Based on what is currently understood is what is being presented here in this thread.....

IF you have any thoughts or information (peer reviewed papers) please present them!!

Otherwise please be tolerant of my limited understanding of the Milky Way Galaxy and how it works according to the models I currently understand! I am very happy to assimilate NEW information and if you have this then please present it!! Give me links so as I can read and hopefully understand.
