  1. Yes, that was complete nonsense. :-)

  2. She isn't good at science, either. ;-)

  3. Because the definition of force does not include gravity. Newton called ONE effect that causes relative motion right, he didn't call ALL such effects correctly. The problem for most people is that we don't teach it like that in school. Instead we are pretending that Newtonian gravity is the correct solution and that everything is fine. They already knew better at the time of Newton, we just didn't have the observational data to go beyond what we knew could not have been entirely correct. Now we do and it would be better to teach forces as one thing and Newtonian gravity as a completely different one right from the beginning.

  4. Einstein had a lot of false ideas about a lot of things. Physics was never about numerical laws. Taking Einstein literally about these things leads to a complete misunderstanding of physics.

  5.  @stewiesaidthat  And what's up with the sock puppet play? :-)

  6.  @stewiesaidthat  Let me give you some more attention, then. The pigeons aren't in the park, yet. I need to feed something. :-)

  11.  @jeremycleary2002  And there is the kid who doesn't know what the word "theory" means. Let's give him some more attention, everybody. ;-)

  12.  @jeremycleary2002  Dude, you can look up the meaning of "theory" on your own time. I am only here to warm your basement by giving emotional support. ;-)

  13.  @stewiesaidthat  Yes, that was bullshit and I don't read bullshit. Hope you fell better. ;-)

  14.  @stewiesaidthat  Yes, that was bullshit. :-)

  15.  @stewiesaidthat  Yes, we agree that whatever you are posting here is bullshit. ;-)

  16.  @stewiesaidthat  Yes, we can agree that that was bs, too. :-)

  17.  @stewiesaidthat  Of course not. You are one. I will give you attention anyway. ;-)

  19. Your cell phone can measure acceleration just fine without reference to any other part of the universe. You need to pay attention to your cell phone, even if you haven't been paying attention to high school physics. ;-)

  20. A paradox is a teaching tool so that people with low attention span can learn non-trivial lessons. Can you see what the lesson here is? :-)
    1
  21.  @vesuvandoppelganger  The lesson is that events that are happening in different locations but at the same time in one particular rest system are NOT causally connected.

  22. That's coordinate acceleration. Physical acceleration is absolute because it can be measured in a single coordinate system (no other system is needed). Your cell phone can do it for you.

  23. Where did you get that nonsense from? :-)

  24. Gravity was never a force. Even Newton knew that. You were simply not paying enough attention in high school.

  25.  @familienglum3902  Why are you insulting your family? I am sure there are a few smarter family members there, too. ;-)

  27. Yes, that bullshit came from the internet... like Trump's huge hands. ;-)

  28. Let me give you attention for failing K-12. ;-)

  29. Congratulation to failing. ;-)

  30. All time is the measurement of the observer. Time is simply that which the clocks show. The assumption in Newtonian mechanics was that all clocks are equal and that they are showing the same time no matter where they are and what their physical history was. That turns out to be false. The times that clocks show depend on their locations and relative motion histories. Nothing really exciting here.

  31. Time is that which the clocks show. It's amazing that so many people can't even retain 7 word definitions. Must be the binge drinking. Or maybe there is too much lead in the water. ;-)

  32. @ There is no such thing as "time" without clocks. That's just one of those nonsensical philosophical ideas that just don't want to disappear, no matter how many times it is being pointed out that science does not speak of unmeasurable things. Only religions and binge drinking people who are close to passing out are talking about such nonsense. ;-)

  33. @ Yes, let me give you some more attention for mentioning Einstein. ;-)

  34. Time is not really a dimension. Time is that which the clocks show. You can define a time unit any which way you like, depending on what's convenient. In SI we use the second because it's a convenient unit for human time measurement. Theoretical physicists might end up with something closer to the period of the ground state to ionization energy transition of hydrogen (10^-16seconds or so).

  35. Tesla was very good at making a fool of himself. You are following right in his footsteps. ;-)

  36. We can. Objects in free fall are simply not accelerating (but they are still experiencing tidal forces). This is where actual physical coordinates and naive mathematical coordinate systems differ. The problem is solely with the naive mathematical coordinates. The world just ain't so.

  37. Yes, you weren't paying any attention in high school science class. So what, though? :-)

  38.  @edwardmacnab354  If you are still stuck on Michaelson-Morley, then you were definitely not paying any attention. One can derive all of special relativity algebraically with a few dozen lines of high school level math using nothing but Galileo's correct understanding of the relativity principle. Electrodynamics never even gets close to being involved in that. ;-)

  39.  @edwardmacnab354  Galileo didn't talk about math. He talked about ways to observe relativity in the everyday world. You need to pay more attention to reality. ;-)

  40. Time doesn't slow down. What slows down is the flow of energy between two systems.
