De-Broglie Momentum Equation
It can be shown that
	7.1
	7.2
For , i=1,2,3, then and in the weak field approximation equation 7.2
for the 4th component of momentum reduces to
	7.3
For , ,  and solving equation 7.3 gives
	7.4
For r/t=c and , from equation 7.4
	7.5
Since the LHS of equation 7.5 is positive, then ie greater than the Planck length
