Graphical timeline from Big Bang to Heat Death
This article relies largely or entirely on a single source. (August 2021) |
This is the timeline of the Universe from Big Bang to Heat Death scenario. The different eras of the universe are shown. The heat death will occur in around 1.7×10106 years, if protons decay.[citation needed]

[edit]Scale
[edit]Usually the logarithmic scale is used for such timelines but it compresses the most interesting Stelliferous Era too much as this example shows. Therefore, a double-logarithmic scale s (s*100 in the graphics) is used instead. The minimum of it is only 1, not 0 as needed, and the negative outputs for inputs smaller than 10 are useless. Therefore, the time from 0.1 to 10 years is collapsed to a single point 0, but that does not matter in this case because nothing special happens in the history of the universe during that time.
year | log10 year | combination of log10log10 year and -log10(-log10 year) |
---|---|---|
1010000 | 10000 | 4 |
101000 | 1000 | 3 |
10100 | 100 | 2 |
1010 | 10 | 1 |
102 | 2 | 0.30 |
101 | 1 | 0 |
100 | 0 | undefined but here forced to 0 |
10−1 | -1 | 0 |
10−2 | -2 | -0.30 |
10−10 | -10 | -1 |
10−100 | -100 | -2 |
10−1000 | -1000 | -3 |
The seconds in the timescale have been converted to years by using the Julian year.
