      What I don't quite get is that Time is abstract, it is merely the framework we use to calibrate Change. Change is the underlying reality to which Time references. And Change rate is specific to each quantum event. Are you saying that the rate of Change alters?

      I know that the light pulse on the top of the box flows faster than when it hits the bottom, but waht's the difference from the perspective of the person inside the box?

      Really not understandble. I think, its very simple to measure the influence of gravity (g) on time. Put a watch in a box and let it fall down from the sufficient height. In this case, g=0 on watch. Then check if any time difference between watch in the box with another watch (g=9.81) on the earth. Show us this result. Thanks!

      Gravity iš easy undestand jos it works. Kodėl nesukuria 2 magnetus kurių vienas yra žemėje kitas yra kosmose. Vienas su kitu magnetai sujungti lazerio pagalba kad sinhronuotusi kosmose esantis magnetas su žemės jog pakilimas būtu vienodas. Ir veiktų tam tikras magnetinio lauko poliškumas kuris keltų daiktus į kosmosą. Tai yra švelnus pakilimas palaipsniui didinant magnetinio lauko pajėgumą ir daikto kilimą. Ir YouTube esant translate from Lithuanian. Whese wordpeling guess in phone is killing me 😅

      wait till science finds out the reason why I can't find its graviton is because gravity is a force that flows like water pushing us down together not pulling us down from inside. it also has all kinds of very interesting properties like water flowing through a river. the flow of gravity what you need to say is directly Associated to time. Gravity time in some places in space turn into something entirely different Sue much where it seems like a force they could fill in a cup and drink. it's quite tasty.

      I don't understand.
      When the box is falling in the first example (On Earth with gravity) .., the lady feels weightless as if there is no gravity present (I assume providing the box is a specific weight to match her speed). But I think you would still feel the force of gravity pulling you down.., as opposed to free floating in deep space. Where you would feel no gravity.


      But in the deep space example.., she is dragged with the box.
      But that is due to the box pulling her along.
      So why do we assume there is gravity? Just because we are being pulled to the box floor?

      But wouldn't she be able to push herself away from the floor, and match the box's speed?
      Thus not feeling "gravity" again?

      In the example of the box falling in Earth's gravity, the girl will always feel weightless, regardless of the weight of the box. This is due to the fact that, in the absence of air resistance, all objects will fall due to gravity at the same rate, regardless of their mass. In the example of the box in space, the girl can't match the box's speed to feel weightless, because the speed of the box is always increasing due to the fact that the box is accelerating.

      Gravity and acceleration different so you can not say this is accurate. Yes if you accelerate the time will be different but if you resume constant speed the time equalizes. The is due to space differences not time. Constantly accelerating away from the first pulse before you release the second. Each pulse you are creating more distance due to the greater speed at that moment. Does gravity effect time? Yes, but not in the way the video illustrates.

      Imagine you have a string with a marker that that leaves a mark every 2 seconds. Now you pull that string along a table at a constant speed. You have regularly spaced marks. Do it again but keep accelerating your pull, your marks keep getting further apart. By doing this you did not defy time (time travel). But you did create more gravity on the marker due to acceleration. To dilate time you have to dilate space simultaneously. This example includes separation of time by creating a greater distance. Which is not dilating or distorting space.

      I still cant understand why the body falls due to the changing rate of time progression.

      So the increase in gravity as you near the event horizon compresses time?

      When Super dense matter is compressed enough it forms a black hole.

      So is it safe to say that Time can be compressed in the same manner as matter given enough gravitational force?

      Through the looking glass- seeing it from the opposite side... (absolutely equal BUT in all ways perfectly opposite!) . Picture yourself waiting to fall feet first into the Black Hole. Your head will age to the ripe old age of retirement before your feet do! Gravity is caused by faster "Time" higher pressure toward slower "Time" low pressure. Acceleration, therefore should be Change in Time Divided by Distance (A=Delta T/D), not Change in Distance divided by Time (A=Delta D/T) as we are used to seeing. The moving box is a mirrored version of the REAL equation for Gravity! (A=Delta T/D). Time Factor Theory. Copyright 2010.

      важно также понять, что есть "измерение отрезка времени". если мы измеряет время в движущейся системе относительно неподвижной, то мы должны измерять одни движущиеся часы относительно двух (или более) неподвижных часов разнесённых на некоторое расстояние. Если же мы меняем системы отсчёта местами, то мы уже будет сравнивать одни неподвижный часы со множеством движущихся часов (которые могут вести себя очень сложно, учитывая относительность понятия одновременности событий). Отсюда и всякого рода "пародоксы", которые являются неполным пониманием теории.
