  1. Good job! That was funny. We can't even get people to wear masks, how could we make them learn the metric system?

  2.  @jaixzz  If it were only crackpot theories, we wouldn't have put men on the moon or developed nuclear weapons.

  3. That is the simple explanation of it. The dark part of the black holes is where the escape velocity is greater than the speed of light.

  5. General relativity and curved time explains gravity.

  8. Dark matter DOES interact GRAVITATIONALLY with visible matter, so the center of mass of a galaxy would be the same center. It DOESN'T interact with the ELECTROMAGNETIC FIELD, so there's not a theory explaining how to detect it without photons.

  10. ​ @ronginzler6600  The speed of light is a constant. If it wasn't a constant and could change velocity, it would need mass. I.e., from Newton's First and Second Law, the only way to change a velocity is to apply a force. In Relativistic Physics, all particles with no mass move at one speed: The Speed of Light. Looking back in time at Type-1a Supernova, we don't see matter moving superluminal velocities; we also see gravitational interactions following the same magnitudes of Newtonian Gravity and General Relativity. We know this also from Inductive reasoning. If relativity and the laws of physics were wrong, they wouldn't be able to consistently explain observations

  12.  @musicalADD_theband  Right now, all we have is the gravity of Isaac Newton and Albert Einstein. We can explain it as a "force" or "spacetime curvature," but no one knows why it's a property of the universe.

  13.  @musicalADD_theband  The radius of the earth and moon hasn't changed, so how would it apply to their apparent attraction.

  17. It's a video for a general audience. Explaining classical mechanics with geodesics, differential geometry, 4D spacetime, and abstract concepts like tensor fields would ruin the video. The prerequisites for special and general relativity ("GR") include a mastery of Newtonian mechanics and Galilean relativity. IMO, GR is a beautiful theory, but the mathematics and theoretical framework are beyond most non-physics majors.

  18. Eigenchris, Physics with Elliot, Science Clic, Sean Carroll, and the Susskind GR lectures at Stanford offer the best options for learning or re-learning relativistic physics and quantum mechanics outside of a university and textbook.

  19. That's Newton's Third Law. In General Relativity, your example would reduce back to Newtonian Mechanics ("Special Relativity" or "Flat Spacetime") because you would get the same answer without using complicated tensor calculus for curved spacetime and geodesics.

  25. Ever heard of "gravitational potential energy'? Force, energy, acceleration, and spacetime curvature are all related by "work-energy relation."

  27. It's mostly preference of terminology, but the ultimate source of gravity in all theories are the local energy/mass density and the energy and momentum of matter fields. It's not a classical force, ΣF = ma, in Newtonian mechanics. It's a "fictitious force" added to a non-inertial frame to be consistent with Newton's Laws of Motions. In general relativity ("GR"), the effects normally associated with a gravitational force and acceleration due to gravity are spacetime curvature. Newton's gravity and predictions can be reproduced and described as spacetime curvature rather than a force. In the standard model of elementary particles, the "graviton" is a theoretical force-carrying particle of gravitational interaction. There's no settled, verified, and tested theory of quantum gravity. GR and Newton's gravity are the current theories and neither requires the "graviton" to explain gravity.

  29. Spacetime of your Grade curved toward [ D- ], i.e., the same as your test scores and midterm grades accelerated toward [ D- ]; the same results as if the frame of reference was inertial. The average grades remained on a geodesic path toward C+.

  31. He said, "Despite remaining stationary, in general relativity, a deviation from the straight-line geodesic is an acceleration." Did you mean "inertial motion," instead of "initial acceleration?"
    1
  32. It's okay to use the "F word." Wouldn't the tidal forces ("deviations from geodesic paths in GR") indicate you're not in a uniform gravitational field; and from that, the equivalence of gravity and acceleration wouldn't apply? A change in coordinates systems wouldn't be able to remove the affects of gravitation.

  35. Yes. I've got to admit Derek's content is bad ass.

  36. They're both considered "fictitious forces" or "inertial forces." You're not confusing them with tidal forces, are you?

  37. LMAO! It takes years to understand relativity, but yes, I finally understand what he and Einstein were (and "are") saying about gravity.

  38. "Gravity isn't a force, and the gravitational field doesn't exist in GENERAL RELATIVITY." Quantum Gravity, supersymmetry, QFT, and String Theory are not in GENERAL RELATIVITY.

  39. Which physical constants are you suggesting modern physics mistakenly assumes to be invariant (e.g., "G" or "c" as variables)? The expansion observations were originally from Hubble and by applying thermodynamics and General Relativity on cosmological scales. Einstein's significance was to make Newtonian Gravity compatible with Special Relativity

  40.  @ronginzler6600  Observing space is looking back in time. The gravitational constant and speed of light hasn't changed.

  44. They'll still die regardless of this research. We could have solved hunger in 2019 but still lost millions from coronavirus complications from 2020-present.
