Predicting the future is a difficult task because the effects of one event impact and change events that lie beyond it. But some things in our universe follow such precise laws of behavior that scientists, knowing how they behave, can make certain predictions of the future, at least on a broad scale.
Not only do scientists have the ability to predict the extreme future of the universe, they have actually sat down and done it, charting the universe’s course for the next 3x1043 years.
In 25,000 years, the Arecibo Message, which is a packet of data transmitted by radio signal in November 1974, reaches its destination, the globular cluster Messier 13.
In 50,000 years, assuming that the Arecibo Message is received by intelligent beings in the Messier 13 cluster, and they send a message back, their message will then be received on Earth.
Anywhere from 1 trillion to 100 trillion years from now, the formation of new stars ends as galaxies deplete the gas clouds that are necessary to form new stars, according to Fred C. Adams, professor of physics at the University of Michigan. This marks what astrophysicists call the Degenerate Era. With no remaining free hydrogen to form new stars, all remaining stars will slowly exhaust their fuel and die.

...and then the Universe implodes in on itself and starts all over

Interseting stuff, I'm glad, according to the information, I will be long gone, and forgotten. However, a million years, wow, I'd think our sun would snuff us out way before then. If not, a rogue asteroid that comes in that was undected would kill us off. In science, all of what they are saying is an educated guess. For space anyway. That's if we haven't nuked, or killed each other off for our religions...
Not these predictions, the first one isn't going to happen for 25,000 years. 100 years from now I doubt these will be much different.

In 100 years time, we will look back at our predictions and laugh at how silly we were.
Seems to happen throughout history.
This is related to the Fermi Paradox....if there are other intelligent life forms out there in our galaxy, and it only takes this amount of time to colonize the entire galaxy...then where are they? The galaxy is billions of years old so they should be everywhere by now. But we don't see them.

In anywhere from 5 million to 50 million years from now, even traveling at sublight speeds, humanity could colonize the entire galaxy.

S&F I really enjoyed reading that
Just wish that I had been born 50-100 million years later than the 1980’s so I could have witnessed mankind colonising the stars.
