Hubble's Law and it's relation to Quantum Mechanics

AI Thread Summary
Hubble's Law describes the expansion of the universe, suggesting that galaxies move away from us at speeds proportional to their distance. While many scientists speculate on a connection between Hubble's Law and Quantum Mechanics (QM), the relationship remains unclear and is considered an area of ongoing research. Some argue that cosmological models can be developed under the assumption of a homogeneous and isotropic universe, which leads to the formulation of Hubble's Law. The current understanding of this connection is still in its early stages, likened to an "elephant in a dark room." Further exploration is needed to clarify how Hubble's Law might integrate with quantum theories.

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

Most scientists believe there is a connection, but, we are still in the 'elephant in a dark room' phase of discovery.

I don't think there much of a connection.

You can get a lot of cosmology by assuming that the universe is homogenous and isotropic. Once you assume that one part of the universe is more or less like another part, then you end up with something like Hubble's law.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Can the signal WOW be explained by the maser effect?'

This hypothesis of scientists about the origin of the mysterious signal WOW seems plausible only on a superficial examination. In fact, such a strong coherent radiation requires a powerful initiating factor, and the hydrogen atoms in the cloud themselves must be in an overexcited state in order to respond instantly. If the density of the initiating radiation is insufficient, then the atoms of the cloud will not receive it at once, some will receive it earlier, and some later. But then there...
