@layman,
Dear layman and everyone reading here, and also our colleagues like one Maxcondana who has a good education in physics, and others with good knowledge of physics, and how to apply all these amazing learnings in particular of relativity physics, and also of course with quantum mechanics, to their talking in web forums.
First, just a question I ask myself, namely, scientists who are conversant with quantum mechanics, are they also conversant with Einstein's relativity: for the first is into the realm of the smallest bits components of matter, namely, subatomic particles, and the second, namely, relativity theorizing, is into massive lumps of matter, like distant suns and galaxies in space...
My question is how is it that the quantum mechanics enthusiasts talk about galaxies like they are subatomic particles, when they are not; on the other hand the scientists, astronomers and astrophysicists, who deal with stars and galaxies, they are not to my
limited reading on astronomy and astrophysics (so correct me for my ignorance), they are not into talking about stars and galaxies, as though these massive entities of matter are what, like subatomic particles...?
You see, the enthusiasts of quantum mechanics are into very very very nth times very small space that is occupied by say one subatomic particle, while the astronomers and astrophysicists are into space that is very very very nth times very grand, measured in term of light years, that is occupied by suns and galaxies.
That is my question or my contemplation of the material universe, and my impression is that the experts of quantum mechanics seem to be with more swollen heads, than the astronomers and astrophysicists.
See next post from me.
