A Snapshot of the Universe 3 Trillion Years From Now
ultracool wrote with a link to a Science Daily article that requires that you think long term. Really long term. Case Western Reserve University physicists are theorizing that trillions of years from now the universe will become 'static'. Essentially, the information that we use to gauge our Galaxy's position in the universe will have moved beyond the 'visible horizon. "What remains will be 'an island universe' made from the Milky Way and its nearby galactic Local Group neighbors in an overwhelmingly dark void ... The researchers followed up that discussion with one tracking early elements like helium and deuterium produced in the Big Bang. They predict systems that allow us to detect primordial deuterium will be dispersed throughout the universe to become undetectable, while helium in concentrations of approximately 25 percent at the Big Bang will become indiscernible as stars will produce far more helium in the course of their lives to cloud the origins of the early universe."
Doesn't this mean that the universe may be much older than we can currently detect in that there may be a lot more of it out there beyond our current event horizon which drops off at about 13.7 billion years? Maybe it is 20 or 30 billion years old but we can only detect it to the 13.7 billion year line.
