The Scale of the Universe is an interactive online visualization tool first created in 2010 by Cary and Michael Huang, two brothers from Moraga, California. [1] [2] ...
There are four fundamental interactions known to exist: [ 1] The gravitational and electromagnetic interactions produce long-range forces whose effects can be seen directly in everyday life. The strong and weak interactions produce forces at minuscule, subatomic distances and govern nuclear interactions inside atoms .
Cosmic Calendar. 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 . In this visualization, the Big Bang took place at the beginning of January 1 at ...
From about 9.8 billion years of cosmic time, [13] the universe's large-scale behavior is believed to have gradually changed for the third time in its history. Its behavior had originally been dominated by radiation (relativistic constituents such as photons and neutrinos) for the first 47,000 years, and since about 370,000 years of cosmic time ...
Zero on 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 is denoted by 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, where 4e+09 represents 4 times 10 to the power of 9.

The universe is bathed in highly isotropic microwave radiation that corresponds to a thermal equilibrium blackbody spectrum of roughly 2.72548 kelvins. [7] The hypothesis that the large-scale universe is homogeneous and isotropic is known as the cosmological principle. [116]
e. This timeline of the Big Bang shows a sequence of events as currently theorized by scientists. It is a logarithmic scale that shows second instead of second. For example, one microsecond is . To convert −30 read on the scale to second calculate second = one millisecond. On a logarithmic time scale a step lasts ten times longer than the ...
