    I Which theory of time is the most evidence-based?

    It sounds like you are trying to come up with a coherent description of physics by stitching together sound bites from popularizations you have read. It would be nice if this worked, but it doesn't. You either have to put in the effort to learn the subject properly, from classes and textbooks...

    Admissions Do I have a good shot at CalTech/MIT's graduate program for physics?

    I see you aren't going to take my advice to focus on where you are now. <sigh> This is something you absolutely should not be worrying about now. You have no idea what you want to be doing for your PhD (even if you think you do), and little-to-no idea of the sort of environment you will do...

    I Solutions of Einstein's equations give flat galactic rotation curves

    I have a really, really hard time believing rotation curves are caused by some hitherto unknown GR effect. Dark Matter gravity is 5x luminous matter gravity. Newtonian gravity is (approximately) the T00 term in the stress-energt tensor. The largest other terms are down by one factor of β, which...

    B Strange cosmic particles in my detector

    The median cosmic ray energy is about 1 GeV, which means it will penetrate 2 feet of steel. Lead? It's denser, so maybe 16-18 inches. And that buys you a factor of 2. If you need to get away from cosmic rays, you need to go down in a mine. Even there it never zeroes out completely. But it's...

    Admissions Do I have a good shot at CalTech/MIT's graduate program for physics?

    First, those schools have very different programs. Picking a graduate school is more about "fit" than prestige. The big name school may not even do the kind of research you are interested in. Chasing prestige is a bad strategy. You can't each prestige. Second, some schools are just not going...

    A Transition frequency -> Rydberg oxygen atoms

    Not to a state of 7+ they aren't. That would take ~20 million degrees.

    I Which theory of time is the most evidence-based?

    That's just stringing words together. People are being polite. It's nice that they are trying to help, but if you don't know what you are looking for, there is no way they know what you are looking for. <reference to deleted post removed>

    A Transition frequency -> Rydberg oxygen atoms

    12 eV is not enough to strip 7 electrons from oxygen.

    I Axial Version of the Phi Meson

    See Section 8, "A Naming Scheme for Hadrons", particularly Table 8.1. That's all the spoon-feeding I intend to do. If you have more questions, show me you have done your part.

    B Strange cosmic particles in my detector

    There is no way a "lead box" is going to work. Cosmic rays are mostly muons and penetrate lead, especially it is thin enough to make a box. Some of the backgrounds are internal to the phone, and some may be external. The sensor is way, way too small to measure cosmic rays. As far as finding a...

    A Is Chern number exactly an integer of half-integer?

    What is a "Chem number"? Google just gives me the phone number of a company called "Chem Care".

    Stargazing Dark matter and its effect on the orbit of stars

    I certainly hope not. We ignorant yahoos in the sciences have actually done the calculation of what is the impact of dark matter on gravitational lensing. And you know what? It matches what we see - not what you guess.

    Programs Help me decide: physics or chemistry!

    Why do you need to decide now? Enter your university, take the university's offerings in physics and chemistry - which you probably need to take anyway with either major - and decide then.

    Other Transition from theoretical physics to astronomy

    So, let me see if I understand the question. You are asking if an unspecified program at an unspecified level (BS, MS, PhD) unspecified university in an unspecified country in the overly broad topic of "theoretical physics" will adequately prepare you for an unspecified research position in an...
