Is there a relationship between red shift of galxies and zero point energy?

Red shift and zero point energy
In summary, there is a current belief that the redshift of galaxies is affected by the interaction between light and space, as proposed by Fritz Zwicky and Einstein. However, modern theoreticians, such as Fotini Markopoulou-Kalamara, have suggested that the delay of high-frequency electromagnetic waves, compared to low-frequency waves, may also play a role. The MAGIC consortium has recently published findings supporting this idea. As for the zero point energy, there is speculation that it may change over time due to the slight index of refraction caused by space not being a complete vacuum.

If, as Fritz Zwicky thought, redshift arises from light's interaction with the space through which it propagates, yes. Einstein thought that light had to interact with space (as a transmissive medium, too). Today, we are MUCH smarter and have no truck with such crazy ideas. 
There are a few modern theoreticians including Fotini Markopoulou-Kalamara, who think that light may interact with the the transmissive media (space) through which it propagates, and that since high-frequency EM must interact more frequently than low-frequency EM, that high-frequency EM must be delayed relative to the low-frequency EM. The MAGIC consortium has recently published about such a delay, though this observation has not been replicated.

zero point energy changes?
Thanks for the reply that is what I have read also about space no really bieng a compleat vacuum there fore causeing a slight index of refraction. Any thoughts on zero point energy changing over time?

1. What is red shift?
Red shift refers to the phenomenon where light from distant objects in the universe appears to have longer wavelengths, or is "shifted" towards the red end of the visible light spectrum. This is due to the expansion of the universe, which causes the light to stretch as it travels towards us.
2. How is red shift related to the Big Bang theory?
The discovery of red shift in the early 20th century provided evidence for the expanding universe, which is a fundamental aspect of the Big Bang theory. This theory suggests that the universe began as a singularity and has been expanding ever since, causing the observed red shift in light from distant objects.
3. What is zero point energy?
Zero point energy is the lowest possible energy that a quantum mechanical physical system can have. It is the energy that remains in a system even at absolute zero temperature, when all other forms of energy have been removed. This energy is thought to be responsible for the constant motion of subatomic particles.
4. How is zero point energy related to red shift?
Red shift and zero point energy are not directly related. However, some theories suggest that zero point energy could be responsible for the expansion of the universe and the observed red shift in light from distant objects. This is still a topic of ongoing research and debate among scientists.
5. Can zero point energy be harnessed for practical use?
While zero point energy is a fascinating concept, it is currently not possible to harness it for practical use. The energy levels involved are extremely small and difficult to measure or manipulate. However, there is ongoing research in this area, and it is possible that future advancements may lead to practical applications of zero point energy.
