An important conclusion of both string theory and loop quantum gravity
theory is that space and time are ultimately discrete. A consequence of
discrete space is that there is empty space between the basic elements of
space. Analogously, there are empty times between the times where time
exists. When time does not exist, it is meaningless to consider the existence
of the universe. In this note we consider a discrete-time interpretation of
the Planck-Einstein equation and draw a curious conclusion about the real
age of the universe.
