Since the universe is expanding, the equation for that expansion can be "run backwards" to its starting point. The Lambda-CDM concordance model describes the expansion of the universe from a very uniform, hot, dense primordial state to its present state over a span of about 13.77 billion years [12] of cosmological time.
Given our assumed half-life of the proton, nucleons (protons and bound neutrons) will have undergone roughly 1,000 half-lives by the time the universe is 10 43 years old. This means that there will be roughly 0.5 1,000 (approximately 10 −301 ) as many nucleons; as there are an estimated 10 80 protons currently in the universe, [ 41 ] none ...
The universe has appeared much the same as it does now, for many billions of years. It will continue to look similar for many more billions of years into the future. The galactic disk of the Milky Way is estimated to have been formed 8.8 ± 1.7 billion years ago but only the age of the Sun, 4.567 billion years, is known precisely. [69]
The Five Ages of the Universe is a popular science book written by astrophysicists Fred Adams and Gregory P. Laughlin [1] about the future of an expanding universe first published in 1999. [ 2 ] Book contents
The Universe is an American documentary television series that features computer-generated imagery and computer graphics of astronomical objects in the universe plus interviews with experts who study in the fields of cosmology, astronomy, and astrophysics.
A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.8 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
After Earth is a 2013 American post-apocalyptic action-adventure film co-produced and directed by M. Night Shyamalan, who co-wrote the script with Gary Whitta.The film was loosely based on an original story idea by Will Smith about a father-and-son trip in the wilderness before it was eventually reworked into a sci-fi setting, taking place 1,000 years in the future where humans evacuated Earth ...
The narrator then travels into a distant future in which humanity has died and then even further, past the death of Earth. Hodgson's The Night Land (1912) describes a time, millions of years in the future, when the Sun has gone dark. The last few millions of the human race are gathered together in a gigantic metal pyramid, the Last Redoubt ...
