Can someone say a few words on Hubble's law as (if) it relates to QM?

Hubble's Law is a fundamental principle in astronomy that describes the relationship between the distance and velocity of galaxies in the universe. It states that the more distant a galaxy is, the faster it is moving away from us. This law is based on the observations made by astronomer Edwin Hubble in the 1920s. The theory of Quantum Mechanics, on the other hand, is a fundamental principle in physics that describes the behavior of particles at the atomic and subatomic level. The two may seem unrelated, but they are both crucial in our understanding of the universe.
Hubble's Law provides strong evidence for the theory of the expanding universe. The law states that the velocity of galaxies is directly proportional to their distance from us. This means that the farther away a galaxy is, the faster it is moving away from us. This is consistent with the idea of an expanding universe, where the space between galaxies is constantly increasing, causing them to move farther apart.
Quantum Mechanics plays a crucial role in understanding the movement of galaxies. It helps us understand the behavior and interactions of particles at the subatomic level, which ultimately affects the movement and behavior of larger objects, such as galaxies. Without Quantum Mechanics, we would not be able to accurately predict the movement and behavior of galaxies as described by Hubble's Law.
Hubble's Law has had a significant impact on our understanding of the age of the universe. By measuring the distances and velocities of galaxies, we can use Hubble's Law to calculate the rate of expansion of the universe. This, in turn, allows us to estimate the age of the universe. This estimation has been refined over the years, with the current age of the universe being estimated at around 13.8 billion years.
Hubble's Law can be applied to most galaxies in the universe, but there are some exceptions. Galaxies that are close enough to each other can have gravitational interactions that affect their velocities, making them deviate from the expected relationship described by Hubble's Law. Additionally, Hubble's Law is only accurate for relatively nearby galaxies. For galaxies that are farther away, other factors such as the expansion of the universe and dark energy must be taken into account.
