A look back in time billions of years to the origin of the Big Bang. Leading physicists and historians theorize what happened before the bang occurred, how the physical nature of the universe unfolded as energy became matter forming stars and galaxies, and how the universe continues to expand outward at an ever-accelerating rate.
This episode explores the theories of the big crunch, the big rip and the big freeze, that are postulated by physicists as possible fates for the universe. [3] Al-Khalili indicates that the difficulty in understanding this is our limited ability to comprehend something of such immensity both physically and philosophically. [4]
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 ...
[15]:§VID The decay time for a supermassive black hole of roughly 1 galaxy mass (10 11 solar masses) because of Hawking radiation is in the order of 10 100 years, [16] so entropy can be produced until at least that time. Some large black holes in the universe are predicted to continue to grow up to perhaps 10 14 M ☉ during the collapse of ...
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.
This time happens to correspond roughly to the time of the formation of the Solar System and the evolutionary history of life. Stelliferous Era: 150 Ma ~ 100 Ta [19] 20 ~ −0.99: 60 K ~ 0.03 K: The time between the first formation of Population III stars until the cessation of star formation, leaving all stars in the form of degenerate ...
