What "large size" unit of length could be considered at the opposite end of spectrum from Planck's length?
Is there a table of smallest and largest value for various physical quantities that can be defined from well-known constants?
I was teaching the exponential function and scientific notation to kids and I was looking for example of physical quantities that occur on vastly different scales. Length is the easiest and there are some demos as in The Scale of Universe. As the size of universe seems to be a function of time I wondered about other large lengths.
