The ultimate fate of an expanding universe
Top: Diagrams of three possible geometries of the universe: closed, open and flat from top to bottom, corresponding to a density parameter Ω0 which is greater than, less than or equal to 1. The closed universe is of finite size and, due to its curvature, traveling far enough in one direction will lead back to one’s starting point. The open and flat universes are infinite and traveling in a constant direction will never lead to the same point.
Bottom: The age and ultimate fate of the universe can be determined by measuring the Hubble constant today and extrapolating with the observed value of the deceleration parameter, uniquely characterized by values of density parameters (ΩM for matter and ΩΛ for dark energy). A “closed universe” with ΩM > 1 and ΩΛ = 0 comes to an end in a Big Crunch and is considerably younger than its Hubble age. An “open universe” with ΩM ≤ 1 and ΩΛ = 0 expands forever and has an age that is closer to its Hubble age. For the accelerating universe with nonzero ΩΛ that we inhabit, the age of the universe is coincidentally very close to the Hubble age.

Graphical timeline of the Universe
This more than twenty billion years timeline of our universe shows the best estimates of the occurrence of events since its beginning, up until anticipated events in the near future. Zero of the scale is the present day. A large step on the scale is one billion years, a small step one hundred million years. The past time have a minus sign, e.g. the oldest rock on Earth was formed about four billion years ago and this is marked at -4e+09 years. The “Big Bang” event happened 13.7 billion years ago.
