Can Dark Energy Undergo Simple Harmonic Oscillation?

[kurious]

If the universe oscillates between a Big Bang and a Big crunch,
can two small volumes of dark energy, at opposite ends of it, be considered to be undergoing simple harmonic oscillation?
The potential energy of an oscillator could be given by G m1 m2 /r where
m1 is the mass of a volume of dark energy, the mass of the universe is10^52 kg,r = 10^26 metres - the current
size of the universe . Since the PE of a simple harmonic
oscillator is given by
PE = 1/2 k x^2, the force constant k becomes 10 ^ -37 m2 assuming r is also about equal to the maximum extension of the oscillator.
using frequency of oscillator = ( k / m2 ) ^1/2,
frequency = ( 10^ -37m2 / m2 )^ 1/2 = 10^ - 18.5 per second.
In other words the universe could oscillate every 10 ^ 18.5 seconds - about
its current age!
Quantizing this oscillator gives its potential energy changing in units of
10^-52 Joules.Could this be the energy of gravitons turning into dark energy as the universe expands and the potential energy of the oscillator increases?

No, it is not possible for two small volumes of dark energy to undergo simple harmonic oscillation. The potential energy of an oscillator is determined by the mass of the two particles, the distance between them, and their interaction with each other. Dark energy does not interact with itself and therefore cannot be used to create an oscillating potential. Additionally, the frequency of oscillation would be far too slow to be practical.
