Extremely fascinating thanks for the share.
Am I the only one who feels sad because my interest leads me to topics I ll probably never will get any answers to. The human lifespan is simply not long enough to observe and follow stellar events. All we do is sift through the past and piece together clues. And the level of information we were able to glean from the surface of our own planet is beyond belief and makes me stand in awe at the pure "potential" the human race has.
But there are a lot of theories floating around, many of which we dont have an answer to...only probabilities and assumptions. I m sad to realize that I wont live long enough to see one of them proving all others wrong providing a real "answer"

Its interesting stuff. I had this theory that Dark Matter is Antimatter. If anitmatter reacts in the opposite way to gravity as normal matter does, then this could explain where all the extra unseen mass is in the universe. There could potentially be antimatter galaxies out there that we cant actually see and as antimatter and matter have an opposite reaction to each other, that could be the reason for the increase in the expansion of the universe.
But I am no expert in these matters and I am sure someone who knows better will knock my theory to pieces. All I do know is that they cannot test antimatter effect to gravity as the anitmatter is destroyed far too quickly.

[re the merging of MIlky Way and Andromeda Galaxy] ...'The merger won’t occur for another three to four billion years, Kirkpatrick says. “That will be about the same time the sun has turned into a red giant, so we will have other problems to occupy us at the time.”'
That's OK then.
That's OK then.
For my part, I would almost be surprised if the humanity is still alive by then.
It's not looking good for sure.
I ve read sci-fi novels in the past which examined the universes lifespan in its totallity and how immortal species would experience it which experience the birth and its end and everything in between. Very ambitious books for sure but written by mere humans....still to even attempt it and succeed in providing a completely alien view on such things...respect.
I m often sad that I ll never going to grasp anything more then a glimpse about the whole picture and whatever I glean is never a 100% answer but rather wild theory due to our limitations to prove things (tho what scientists were able to prove already via math and chemistry....mindbogling). On the other hand my life, while short, is intense compared to other longer living species. We already have things on our planet which could be very well immortal but there are examples of many thousand years...the longer the timespan you observe the one thing comes up which they all have in common....sluggishness sometimes turning to inertance. Its like our own evolution has put us into overdrive bilogically but that comes at the price of burning out quickly compared to other species.
Imagine watching a star die in its entirety. Such things take millions of years...what would you possibly do to not go insane during that time? Even if you consider that some theoretical species might obtain immortality without losing their vitality (machine minds, cloning which is arguable and rejuvenation). In my few decades I m alive I already grew tired of so many things to a level where I simply ignore them and look for new input that might keep my interest. Is it possible to become "tired" of life? The universe and its mechanics would be a good test run.
Its a complex topic
