Modern and Theoretical Physics

So for magnetism we have earths magnetic field, that occurs naturally Electricity we have lightning We have electromagnetic waves come from the sun That covers electromagnetism I think What about the other 3 fundamental interaction of nature

We have several members strugglings with various concepts of dimension at the moment and this seems to come round again and again. So here, (hopefully) is some clarification by analogy. Consider an old fashioned torsion suspension meter and pointer. When the wire supporting the pointer twists about its longitudinal axis the pointer sweeps over the scale, giving us a reading measurable in one or two dimensions on the flat scale., as an angular deflection or as a pair of x, y coordinates like a graph on the scale. In principle the wire is of zero thickness so the twisting itself is not measurable in terms of the axis of the wire. That is the twist t…

I think I understand up to 3 dimensions lmao

I never studied physics past basic physics for engineers and one Modern Physics course. My notion is that while electrons and protons have a mutual attraction for each other neutrons only have an attraction for protons and none for electrons or each other. This is why the neucleus stays together. I say neutrons also have some attraction for protons in neighboring atoms. I had a theory of gravity that it's due to the distribution of the + and - charges in any material, but could never proof it or interferer with this experimentally because the neutrons also exhibit attractions to distant protons. Someone said once I was just talking about Van der Waal's forces. Anyone wh…

Do electric and magnetic fields control the movement of the particle leading to its collision

Hello, While reading about the subject I made this simple calculation (I will detail it so to be sure there is no mistake) : Mass of electron (at rest) is : me = 9,11E(-31) kg = 5,48795181E-04 amu Masse of proton : mp = 1,67252000E-27 kg = 1,00754217 amu sum of both (electron mass being 1000 time smaller) : me+mp = 1,00809096 amu atomic weight of hydrogen (precisely the isotope 1H) (https://chemistry.sciences.ncsu.edu/msf/pdf/IsotopicMass_NaturalAbundance.pdf), is : M(H) = 1.007825 amu. The difference of masses is D = (me+mp)-M(H) = 0,000265963855422 amu Since : c= 2,99792458E+08 m/s, 1ev = 1,60200000E-19 J Calculating the…

Hello, I would like to learn how to model water and its evaporation using molecular dynamics simulation. Perhaps there is anyone who has already done similar simulations and could answer few simple questions such as: What criteria should satisfy water molecule models for this kind of simulation? What could be best choise as water molecule model? What is the best free sofware for doing this kind of calculatins? Best regards, Gediminas

According to modern physics, we know that particles and light behave very differently under observation than they do unobserved. An unobserved field of energy is just that, and evenly distributed field of potential that requires a recorded measurement to “fix” it to a single position or a set path. Most pysiscists also agree that the disparity of energy vs. observation is disproportionately in favor of more energy than we are able to explain at this time. We call it dark energy. I believe, along with many others, that the Universe continues beyond our ability to observe. One possible explanation is the light hasn’t had enough time to reach our vicinity in space.…

Link to the arxiv work published May 31st: https://arxiv.org/pdf/1805.12028.pdf Aparently there is some indirect evidence that a new type of fermion, a „sterile neutrino” with mass might exist and it might be a serious contender for dark matter. I must admit that my hobbyist level physics knowledge was lacking „chirality” up untill now...it seems that on top of spin there is another property of exotic matter which has to do with particle phase when partciles are in motion, it can be clockwise or anti clockwise direction. What bothers me is why haven’t we detected any direct or indirect evidence of a massive particle like this up untill now? @Janus, @swansont, co…

I've started researching an interesting phenomenon known as the Anti-Zeno Effect (AZE), where frequent measurements can induce an increase in the decay rate of an unstable quantum system. Multiple experiments have been done to prove this theory. However, as noted by this article attached down below, this AZE can also be used (theoretically) to speed up beta decay by frequently striking a decaying nucleus with a gamma ray source. Obviously, we would have to take into the account of time-energy uncertainty of the photons be shot at the decaying nucleus. My mathematical knowledge isn't high enough to understand the claim (as mentioned in equations 19 and 20 in the article), …

And is the Higgs mechanism part of electrons?

Has there been any experiment done through chemical analysis to check if mass spectrometry is consistent with our chemical balance? Our current analytical balance has an accuracy of 10¯⁵. The chemical composition by weight of two isotopes forming a compound could be analyzed. This is sufficient to determine a relative atomic mass of two isotopes and to compare with the CODATA values obtained through mass spectrometry. The values should be the same to at least the third decimal. This is a very good test of the reliability of mass spectrometry. We have about 19 monoisotopic elements including Fluorine and Iodine; these two may react with the other monoisotopic e…

A couple of days ago i decided to make public my philosphy of reality as some of you may know so the topic was closed because i dont have completed my unified field equations but it has a new way of describing reality so a moderator suggested me to keep talking about my theory so i wanted to know if anyone is able to find some inconsistency woth my philosophy of reality because i think this is a very important realization as always im very happy to answer any question you may have Thank you I will leave some videos i have made on the topic

I know 1 atom of uranium-238 isn't critical mass, but theoretically, if you could split 1 atom of uranium-238, how much energy would be produced? ~ee

I am seeking some clarification ref quantum fluctuations in space. What could they caused by? The quantum effects are probabilistic, not deterministic. Therefore, a quantum fluctuation has no "cause." Quantum fluctuations are a point change in the energy of a volume of space due to the Heisenberg Uncertainty Principle. Can they be viewed as a result of interference waves moving at light speed in various directions, (similar to the double slit experiment), creating an apparent probabilistic and not deterministic effect. If they are viewed in this way they have a cause but it is not possible to calculate there appearance other than via probability theory. ht…

Is there a gravitational variant of the Schwinger limit? I mean: a strong gravitational field can separate virtual dipoles with tidal forces. The force applied to the positron is different from that applied to the electron (though both are attractive) and, if this difference is high enough, the two particles can be separated permanently. Do you agree with this? Has this occurrence been studied in physics in the literature of the past? I have not found anything on the internet and it seems strange.

There is a theory saying that we all are living in a computer simulation like in the movie 'Matrix'. What do you think about this theory?

Hello science forum! I've been active in other science forums, but this is my first post in scienceforums.net and my question has to do with gravitational waves. The strain of a gravitational wave is at the order of magnitude of 10^-21 meters as shown in the diagram from wikipedia. I'm wondering how is this posible, when the smallest existing particle is at the order of magnitude of 10^16 (quarks)? Is it posible to detect such a small strain? https://en.wikipedia.org/wiki/LIGO#/media/File:LIGO_detector_sensitivity_curve.png

For every action there is an opposite and equal action. Do both occur at the same time? If we observe the effect left right, up down, etc at exactly the same time in a vacuum (meaning all directions all resistance being equal) is there any reason why our measurements should differ by anything other than direction? If there is an initial need for an exchange of information. I'm assuming there is initially. The first law seems to indicate that only the initial need for an information exchange is needed without regard to the final distance when measured. So if two people measure the effect years later at exactly the same time the only difference in their measure should …

Are non local interactions fact or fiction, or is the jury still out. If I google for proof of non locality and it is everywhere, then I google for explanations of non locality using standard theory and I find it.

Hello everyone, i'm not really sure if this is the proper place to ask these kind of questions, but here it goes: Twisting seems to break everything from tree branches to iron wire: Could you twist a rock until it breaks in half using some sort of machinery? What would the cross-section even look like?

Does General Relativity imply that the Principle of Reversibility of Light does not hold in our Universe?

Some time ago I suggested that if electrons and positrons could become gamma rays then gamma rays could become particles. I played with the idea for a while and lost interest. Recently I stumbled across this link to a planned experiment https://phys.org/news/2018-03-underway.html#nRlv converting photons into particles. Could radiation from a black hole become particles? Could radiation from the Big Bang become particles?

I'm paraphrasing and trying to get it right I was reading an article on particle duality that said everything basically exist as both solid and wave. They spoke of a basketball and that the wave footprint was roughly a negative 34 power, so it is way too small to see and is pretty much why basketballs don't flow around things. They also showed a drawing and talked about the double slot experiment, and electron sizes etc. Then a thought occurred. If I think the procces sort of in reverse and imagined the basket ball as a dense medium would that wave footprint be roughly the size something would have to be to possibly pass freely through the basketball? Usi…

Time being the most experienced thing in this universe but can we really describe what time is? Are we in a state of describing time? Ask this question to yourself and then say that can we scientifically define what time is? The motive of this discussion must be to scientifically define that what time is? And ill tell my own theory to describe what time is?
