Electrons placed in a very low-energy cyclotron (often a Penning trap), and measuring the energy (frequency) it takes to excite transitions (spin flips or cyclotron states) Look for papers by Gerald Gabrielse on the subject, for electrons. edit: here's a paper on the proton measurement https://iopscience.iop.org/article/10.1088/1367-2630/14/6/063011/meta

We don't know. It doesn't interact electromagnetically, hence the name "dark" but we have no way of directly measuring it, so we don't know details. We know something is there because of the gravitational effect it has, and hypothesizing matter is the only way we've found to explain what we observe — efforts to explain this by modifying how gravity behaves fail to work when applied to all observations. So dark matter is a placeholder name for something we haven't fully figured out yet.

my hypothesis: dark matter observations are relative
swansont replied to Maartenn100's topic in Speculations
If you are unwilling to calculate the effect, you aren’t doing science. There’s no conversation to be had without quantifying this. -
! Moderator Note Yeah, we keep banning you. The idea is supposed to be you don’t come back. You are not welcome at this site anymore

No such thing as sticking out of the galaxy You can’t. The galaxy is all there is. ! Moderator Note Speculations requires some kind of model, or testable predictions. It’s not the “I have a wild guess” forum.

Size a solution to Fermi Paradox?
swansont replied to coderage9100's topic in Astronomy and Cosmology
It’s the answer to a specific scenario, with one variable, and multiple assumptions. It doesn’t take into account probably billions of things. Much like solving almost any physics problem doesn’t consider the possibility of being hit with a huge asteroid in the middle of the problem. Sure. You need to consider other things in your decision. No claims to the contrary were made. -

Interesting side note to the interstellar travel issue -
Electricity (split from Science Project (static charge))
swansont replied to westom's topic in Classical Physics
No, you asserted this without evidence, contratry to the description of it, and ignored the discussion that supports the lack of resistance. It ties in with your mistaken claims surrounding electricity Sure they do. Electrons and protons have intrinsic magnetic fields. There is no net field if the individual contributions cancel, and no field from charge motion, of course. But the individual charges have fields. -
Was This Atom Entanglement Research Discontinued?
swansont replied to forex10's topic in Quantum Theory
! Moderator Note I have cropped your article and added a link, to comply with copyright rules The article has 94 citations, so others are using this work in doing other research. Also, you could check to see if the authors have web pages describing their research efforts. -
Change the 93 to 95 for Am i.e. 243/95 Am

leapyear has been banned as a sockpuppet (scifimath, physicaldivide, MultiSingularity, cosmicweb, Joseph Lazar, toolbox, pittsburghj0e) and now yearzero as well. Add The-Oracle to the list.

You say you consider elementary particles, and quarks qualify. Protons, however, do not.
-
You mention quarks only as components of neutrons and protons. That’s it. It does not address my point about mass and charge.

Electricity (split from Science Project (static charge))
swansont replied to westom's topic in Classical Physics
And yet you claimed that superconductors have resistance, rather than impedance. And haven’t addressed the shortcomings of your claim. -
Z is the atomic number, so...
-
And you wrote "243/93 Am" which is the mistake people were hinting about. Z didn't change in the reaction, but it must decrease by 2 in alpha decay

Electricity (split from Science Project (static charge))
swansont replied to westom's topic in Classical Physics
There are loss mechanisms other than resistance at play. You have a magnetic field, for example, which can couple to the outside world and dissipate energy. But that’s not resistance. And you have not addressed the scientific objection that you can make a loop with current flow. How can you have a voltage drop? Pick a point on the loop and it must have different voltages for each time the current completes a cycle. Unless you’re MC Escher, that just can’t happen. The voltage at a point is not multi-valued. Your definition falls flat. -
Can I move some arbitrary distance in a featureless dimension? You seem to be suggesting I can’t, by invoking the fallacy of argument from personal incredulity. In physics, time is not a force that causes things to happen.

Electricity (split from Science Project (static charge))
swansont replied to westom's topic in Classical Physics
No, it’s zero. you can’t have a ring of current and also have a continual voltage drop, which is required if there is a resistance. https://en.m.wikipedia.org/wiki/Superconductivity#Zero_electrical_DC_resistance -
How many protons are in Am?

Typically is not exclusively, and the point of all this are those that have been marginalized. -
