Physicists predict that three trillion years into the future, the information that currently allows us to understand how the universe expands will have disappeared over the visible horizon.
"While physicists of the future will be able to infer that their island universe has not been eternal, it is unlikely they will be able to infer that the beginning involved a Big Bang," report the researchers.
According to Krauss, since Edwin Hubble advanced his expanding universe observations in 1929, the "pillars of the modern Big Bang" have been built on measurements of the cosmic microwave background radiation from the afterglow of the early universe formation, movement of galaxies away from the Local Group and evidence of the abundance of elements produced in the primordial universe, as well as theoretical inferences based on Einstein's General Relativity Theory.
What appears almost as a story from science fiction, the cosmologists began to envision a universe based on "what ifs." Long after the demise of the solar system, it will be up to future physicists that arise from planets in other solar systems to fathom and unravel the mysteries of the system's origins from their isolated universes dominated by dark energy.
But the irony of the presence of that abundant dark energy, the researchers report, is that future physicists will have no way to measure its presence because of a void in the gravitational dynamics of moving galaxies.
"We live in a special time in the evolution of the universe," stated the researchers, somewhat humorously: "The only time at which we can observationally verify that we live in a very special time in the evolution of the universe."
