Mag Time
Time is fundamentally a duration; a distance along the nonspatial space-time dimension.
So we can say that the Sun is ↑17.2 old, whereas the Universe is ↑17.638 old. A human, by contrast, generally lives to be ↑9 (32 years) old, and can live to be ↑9.5 (100 years) old.
[See also latency, the time delay between a cause and its effect.]
- ↑-44: Planck time (smallest measurable interval)
- ↑-10: computer cycle
- ↑-2: internet ping
- ↑-1: blink of an eye
- ↑0: a breath (seconds)
- ↑1: a minute (figurative or literal)
- ↑2: a song (short or long)
- ↑3: a movie (short or long)
- ↑3.5: 1 hour
- ↑4: hours
- ↑5: a vacation (1 to 10 days)
- ↑6: weeks
- ↑7: months
- ↑7.5: 1 year
- ↑8: a career (3-32 years)
- ↑9: a human lifetime (decades; ↑9-9.5 is 32-100 years)
- ↑10: a nation (centuries)
- ↑11: history (millennia)
On a larger scale:
- ↑12: all of human civilization
- ↑13.5: 1 million years ago (Mya) (million=↑6 year=↑7.5)
- ↑16.5: 1 billion years ago (Bya) (billion=↑9 year=↑7.5)
- ↑17: age of the Sun
- ↑17.2: age of the Solar system
- ↑17.4: age of Milky Way galaxy
- ↑17.638: age of the Universe
- ↑21: heat death of universe (predicted)
- ↑21.9: the lifetime of Brahma (Hindu mythology)
The biological evolution of humans happened between ↑13 to ↑16 time ago:
- ↑13: Homo sapiens (Species)
- ↑14: hominids (Genus)
- ↑14.7: great apes (Family)
- ↑15.5: primates (Order)
- ↑16: mammals (Class)
- ↑16.2 vertebrates (Subphylum)
- ↑16.4: animals (Phylum)
- ↑16.7: eukaryotes (Kingdom)
