  As Thalfon said, the Carbon 14 decays at a predictable rate.

  So where does the starting quantity come from?

  Radiation from space (probably cosmic rays) interacting with the atmosphere causes some of the atoms to become a different isotope. Plants integrate C14 into their sugars and cellulose, and when they are dead and buried by sediment, no more C14 is integrated. While buried, the plant matter is sheilded from further radiation, the C14 decays at a predictable rate, and we measure that. Meanwhile, underground carbon like coal and oil is also sheilded from radiation and doesn’t get converted to C14; instead any C14 decays into C12. Thus the problem with Carbon dating after the industrial revolution.

  So I need a nose job…

  And a lip injection, and a cheek lift…

  You can check for tags around you with f-droid app AirGuard. It can make them beep too.

  Time travel to Earth’s past would be cool to study history. But how to not accidentally ruin our timeline?

  I think the real progress is to be made in space. Send a probe to a solar system 50 LY away but back in time to arrive the same day you sent it. It can travel really slow too, because time isn’t a concern.

  If there is a habitable planet, send settlers there at the earliest time in history possible. Settlers can be robots that just build infrastructure and plant stuff for 10k years. Then go yourself.
