In the link below:
You can click on the word "Planck Time" in the top row, and it says that 1 Planck time is the the time it takes for a photon to travel 1 step forward.
What I want to know though, is, is this a "made up" time like ex. there is a centrillion centrillion "mini" seconds per second, or is this really suggesting that a photon travels 100 tredicillion steps each second?
Because I want to know how many real seconds or "moments" are in 1 second. 100 tredicillion?
