“It is always wise to look ahead, but difficult to look further than you can see.” -Winston Churchill
There's plenty to learn about, to see and to discover when we look out at the Universe today. From the leftover glow from the Big Bang in the microwave to the hundreds of billions of galaxies and the tremendous variety of stars in our galaxy and others, there's no shortage of mysteries to solve and curiosities to uncover.

But what if we, instead, came about in this Universe 100 billion years from now? How would we perceive our Universe differently, and would we potentially reach different conclusions depending on what was (or wasn't) accessible to us?

The differences are shocking, but maybe more shocking is what we'd conclude about our cosmic origins! Go read the whole thing.

This begs the question, what information have we already lost? While 100 billion years is immense, so is 13 billion years. If the astrophysicist of the future would draw different conclusions about our universe due to a lack of information, are we doing the same thing? And can we compensate for this? Are there things we shouldn't assume? How is Occam's razor cutting us?
Very similar to a piece I read in Scientific American: http://www.scientificamerican.com/article/ad-100-billion-big-bang-goes-…
As usual, a wonderful presentation of what we know of our Universe.
I would ask, have you read Frederick Pohl's novel "The World at the End of Time"? If not I would recommend it to you and, if so, I would ask if the science involved holds up? Allowances being made for artistic purposes, of course.
Pohl belongs to the school of Golden Age sf writers that attempted to stay within a technologically extended science sphere. Not unlike Clarke and Asimov.
Anyway, it's a good yarn.
History is likely to repeat-given Mother Nature or Great Spirit does not take us out first-ready for another way to hold water please apply-maybe we will not have to deal with catheters after all. Be Blessed-SHALOM C. D.
