Three assumptions of radiometric dating

And you have to check to make sure he touches the end for each lap.

Without these observations you cannot be sure that the time is valid.

When I have asked an audience this question they have looked at me incredulously and said, “Starting time?

” They realize that you cannot know how long the swimmer took unless you knew the time on the wristwatch when the race started.

This site begs to differ, with over 8,000 fully searchable articles—many of them science-based. distance = rate x time With radiometric dating we're instead looking to find the time (or age.) The formula would look like this: time = distance / rate So far they've been able to prove that the rate of decay is a constant so we've got one variable.

You can get any date you like depending on the assumptions you make.

And that is what geologists do—they make up an assumed geological history for rock depending on the numbers that come from the geochronology lab that measures the isotopes in the rocks now.

Your statement “Without knowing the starting time it is impossible to establish the time for the race” is false.

If you know the pool’s length and the swimmer’s speed, you can calculate the time for the race.

    "Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
