In Test 1 the number of swings was not equalto the number of seconds that had elapsed.

Let us try the same test again but this time we will use a slightly longer pendulum cord.

1 Full Pendulum Swing = 2 Seconds of elapsed Time.

6 Swings


By changing the length of the Pendulum Cord wecan synchronise the number of pendulum swings

with each second that passes in the hourglass timerso that each full swing of the pendulum (i.e. the return of the

pendulum to its start position) is equal to 2 seconds of elapsed time. (1 half-swing = 1 second of elapsed time)

For this synchronisation to occur at Giza, the ancient designers – through trial and error - would eventually have reached a

pendulum cord length of 39 inches (2 second pendulum swing).


With the duration of the Giza sunset (at equinox) lasting 148 seconds (rounded), we can now use this to define the length of

the Pendulum Gravity Cubit.

148 x 39 = 5,772 inches= 280 AE Royal Cubits (height of Great Pyramid)
