    Help Needed on Science Friendly Software

    I tested Molview just for fun. I took a random compound, Aminoacetic acid, and it produced these two pictures*: *) I selected representation "Van der Waals spheres" and engine "Jmol".

    Have you sen molview or phet? Maybe build or find molecules you need and take screnshots or export? Note, I haven’t tested myself, I just got the links from a contact
  3. You keep repeating that, even after all the things you have been told in this thread. Speculation: are your ideas based on misunderstanding Big Bang cosmology? You seem to argue as if there are parts of the universe where no gravity waves have ever passed (yet)? If so, then I think that discussion requires a separate thread.
  4. Which one? You have presented several revisions, all of them incorrect. Detection of gravity waves, with finite speed c, and hence reaching finite distance in finite time, got a Nobel Prize: So it is considered a well established part of science. Why not try to learn some physics, since you seem genuinely interested in these topics?
  5. Again, nothing new. A gravitational wave, as predicted by general relativity and confirmed by observation, is the same speed as the speed of light (c). Here are the scenarios I see at this time: 1: Keep modifying the equation until it matches observations and gives correct predictions where applicable. The result will be General Relativity*, an already known theory. 2: Keep modifying by adding constraints and adjustments until the equations has no measurable effect and can't be tested. Such changes are trivial to invent and has no scientific value. 3: New theories beyond GR emerge, compatible with GR in areas where GR applies. (Quantum Gravity or similar) Given the progress so far I boldly state that probability for #3 is zero within the scope of this thread. Is there any point of continuing this discussion? *) And other closely related things, I believe it is not necessary to go into extensive details to make a point.
  6. Where is the distance r between m and M in the equation above? What new physics are you trying to describe? Why keep providing incorrect equations, when correct* equations already exists? *) "correct" means well tested, matching existing evidence, reliable within their respective area of applicability.
  7. Something incorrect, such as negative gravity for small values of T?
  8. Did you read my comment on your gravity equation above? You have still not shown anything new that is missing in mainstream physics. You have shown a new equation* for already known concepts and the equation you proposed* seems incorrect. Existing equations matches observations and tests. Your version seems to contradict several things already tested and covered by existing physics. Strange already told you: Adding your proposed [math](1-\frac{ | r'(t) | t}{c( t_{0} +t)} )[/math] would not work well. See gravity in my previous post. *) Side note; I still think it was good that you introduced an equation in the discussion! From a scientific point of view I believe it leads to more fruitful discussions, vague descriptions with zero math are commonly seen in this section of the forum.
  9. Good point. Probably the mixing of static and dynamic situations* for both gravity and electromagnetism is the main reason behind the proposals made by OP. I asked you to analyse your proposed equation for gravity but I see no response. So here are some comments. As Swanson pointed out you seem so mix static and dynamic things. Here is Newton: [math]F=G \frac{m_{1} m_{2}}{ r^{2} }[/math] Note: there is no time dependency as far as I can see. Here is your modified version. I have changed into what I think you mean, you have not yet responded to my request to take the changing radius into account. This is a best guess: [math]f()=G \frac{m_{1} m_{2}}{ r^{2}(t) } (1-\frac{ | r'(t) | t}{c( t_{0} +t)} )[/math] Assumptions made by me: Since you introduced radial velocity [math]v[/math], radius [math]r[/math] is not constant. So I assume you mean [math]r[/math] as function of time; [math]r(t)[/math]. [math]r(t)[/math] depends on radial velocity [math]v[/math] so I assume [math]v[/math] is time derivate of [math]r[/math], [math]r'(t)[/math]. You stated that direction of the radial velocity is not important, so I use absolute value [math]| r'(t) |[/math]. I assume [math]T[/math] and [math]t[/math] uses same changing time component so [math]T[/math] is some starting time [math]t_{0}[/math]+ elapsed time [math]t[/math]. Instead of an equation from Newton we now seem to have a differential equation. Questions: Do you see what strange things this equation suggests? Hint: what would happen, according to your math, to two ideal pendulums, started at different times? Do you see how it seems to differ from the predictions in mainstream physics, how it can be tested and how its is most likely going to fail such test? Maybe it is time to start from scratch, asking questions about mainstream physics in an appropriate mainstream section of this forum? *) I remember many years ago when I studied. Static and dynamic mechanics were separate courses, first static then dynamic Newtonian mechanics.
  10. What mistake in current physics? Speed of light in vacuum known, tested and included in the mainstream formulas. Lets focus on the modified version of Newtons equations that you have proposed. It is already known that Newton does not take gravitational waves, invariant speed of light in vacuum, time dilation and other things that Einsteins relativity handles (SR, GR). There are situations where Newton mechanics applies and situations where Newton mechanics does not apply. Einstein's equations applies to a broader set of situations* and will look like Newton for the situations where Newton applies. Take a look at the for instance: [math]\gamma ={\frac {1}{{\sqrt {1-({\frac {v}{c}})^{2}}}}}[/math] Very simply put: for speeds much less than c the factor very close to 1; Newton and Einstein gives same result unless high precision is required. So there is no need for new equations to cover the issues you describe, you just have to know when and where to use the existing equations from mainstream physics. How do we test that your equation predicts gravitational effects better than Newton and Einstein? Have you analysed your suggested equation for gravity and seen it's implications? The way you have introduced c and t seems to imply some really strange behavior if I understand your descriptions. Hint: take a look at the connection between r, v and t in what you have stated so far. Since this is speculation section I'll let you will work out the details *) Higher speeds for instance. There are also situations where more work is needed; As far as I know GR does not work good for the center of black holes for instance.
  11. Can you show the math? So far I have seen an equation for your proposed modification of Newtons mechanics.
  12. I think that it is already well established knowledge, according to current physics. It does not test the new equation you suggested.
  13. Here are some additional questions regarding the predictions of the proposed equation: When does the equation apply? How can it be tested? Since matter does not seem to pop into existence, what is the value of T when testing? We have: Perfect circular motion: [math]v=0[/math], no effect from the added parameters. Speeds [math]v[/math] close to [math]c[/math]: the equation gives incorrect results (while GR predictions matches observations). For [math]v<<c[/math] we know Newton is a good approximation. Example: space missions using gravity assist* seems to work. So, what situations requires the modifications you suggest? I think you would have to show how Keplers laws are affected and how observations matches your equations. One more; since the distance r seems to depend on v and on t, can you write out the equation taking this into account? *)
  14. I did not know of Demjanov so I searched. Results supports Strange's comment: "Physical interpretation of the fringe shift measured on Michelson interferometer in optical media" paper was retracted by the editors of Physics Letters A.
