What is time? Time is how something changes over this direction. We commonly use the units:

  • Planck time (5.39 * 10-44)
  • Nanosecond (1 billionth of a second)
  • Milliseconds (1,000,000 nanoseconds make a millisecond)
  • Seconds (1,000 miliseconds make a second)
  • Minutes (60 seconds make a minute)
  • Hours (60 minutes make an hour)
  • Days (24 hours make a day)
  • Weeks (7 days make a week)
  • Months (4.3 weeks make a year)
  • Seasons (3 months make a year)
  • Years (365.2425 days make a year)
  • Decades (10 years make a decade)
  • Centuries (10 decades make a century)
  • Milleniums (10 centuries make a millenium)
  • Megamilleniums (1,000 centuries make a megamillenium)

Time goes forward at different rates. Motion slows time down. Just because we think it always goes forward doesn't mean it does. Time can also go back using a wormhole.
