      Это видео - полная чушь, начиная с самого названия, разная скорость течения времени в пространстве это и есть гравитация, точнее гравитация это следствие и чем интенсивнее время замедляется в пространстве тем сильнее сила гравитации.

      So according to your video people in rockets going to space are actually going towards gravity? And if the Earth is a box, we should be stuck only to one side? Flat earthers now have evidence lol I'm really confused now.

      I do not agree in everything you posted on the video.. Maybe, in the beggining I accept some basal theories, but I would like to explain a new way to understand the function of Universe.

      Everything can be explained based on the same Life-Laws of Universe: There is a "NOTHING" inter-related to the "EVERYTHING" (La NADA inter-relacionada con el TODO) by a "SOMETHING", like an invisible force or conector between both sides creating a 3 basic estructural concepts and its Law sintesis:

      NOTHING tends to EVERYTHING using the connector I call "SOMETHING".

      At that point you have to imagine this: Time is constantly influencing on the movement of particles, fotons or electrons, even matter by itself. Time is always present and Time is 1 of the 4 Dimensions of Universe. ... That's why I dont agree with de Elevator explanation you gave in this video. Even if you move the box (the Elevator), that will not change the way time flows... that will not influence the velocity/aceleration of which move the fotons in your explanation, looking at the yellowed-dots flowing between the red and blue estructures in the model you showed in the video. I think every process is based on the same Law, "the Universal Life's Law": The journey or distance between one point (A) and another point (B) always respects the Law that unites both (the distance between both points, A+B). This relation is not influenced by external Gravity, not even by another external forces of the Universe (i am not shure of that yet). Gravity may confuse us by letting our eye see as if in the bottom of the box/elevator there is a lot of yellow-dots meeting together "slowly" and appilating themselves like it's moving slower that side of the box (the bottom, in blue color). On the other side, looking to the roof of the box/elevator (red) it may seem time is flowing faster than the previous explanation nearest the Blue estructure.
      That confuse us in the beggining, but if you integrate all of this Theory, this Universe Life's Law, you may understand that there is no difference between both points, no difference between de Blue and the Red estructure presented on this video. The only truth or Law I respect now is that "the Origin of everything iniciates at an Unique Point (number 0) where all the Universe was generated, similar to the Big Bang Theory, ... and that 'energy' flows from A to B based on the Law I am presenting you today: the movement and energy flowing from the first point (point A) or "the origin" towards the secundary point (point B) is constant. That's the only force, an internal force, that regulates that continuous flow, mantaining the process vital forever... tending again to the Infinite, without breaking previous Laws or Theories.

      In conclusion, the distance or even time between Point A and Point B is like a constant based on its internal continuous force... you cannot infuence time at this point... So the video explanation is not enough for me to understand how all works.
      Time is the only parameter that we use today to measure progress in every process of life. It's not possible that time is slower in one point and faster on the other extreme... even if there exists that Black-Hole in the middle.

      1:30 "In both cases, it will appear to the person inside the box as if the box is standing still"
      How come? In the first case, floating around inside the box won't tell me that the box is stationary, quite the contrary. In the second case, I would even be able to tell when the box changes its acceleration.

      I understand that the theory says something different from what I wrote here, but my problem is that I don't understand what that is. All I can think of is that I would be able to tell that the box is not standing still. Could someone help me, please? I'm genuinely trying to understand the topic

      Thank you for the videos they are helping me get a better understanding (don't change a thing - people will always find a reason to criticize)

      I understand that acceleration and gravity are perceived the the same relative to position. And that time is affected by both gravitational (force?) and acceleration.

      But, are acceleration a gravity actually the same thing?

      Something is wrong here, I think the time between the two photons is less at the bottom than in the top as the box is travelling along opposite direction of photons n photons cover less distance to reach the bottom

      Physics Videos by Eugene Khutoryansky I’m mean when the box is at constant velocity as seen by the outside observer, but it says this happens only when accelerating

      The video is correct and what you said is also correct. What you stated is exactly what the video shows: That the time between light pulses is less at the bottom of the box.

      If gravity is such a weak force how does it stop light in its tracks in black hole
      Do you think varying speed of light is possible
      Maybe light goes much faster when condensing into a singularity
      Just a science reader but
      Light baffles me
      Don't think we've heard the last word on light

      So essentially the weightlessness in a rocket is due to accelerating INTO gravity? And gravity would cause only what's inside the box to stick? The Earth is a box tugged through space by solar portals? Head hurts

      If there is no light coming out of a black hole, does this mean there is no time in the black hole?

      No. Time is a function of distance/speed so, no.
