  • Time dilation and Einstein’s theory of relativity go hand in hand. Albert Einstein is the most popular physicist, as he formulated the theory of relativity, which gave the Energy mass equivalence formula and is directly related to time dilation. But what is time dilation? Time dilation and space time are interrelated. Einstein made one of the most important contributions to physics and had the concept of space time explained. A simple explanation of space time is that it is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. But it is very important to understand that the general theory of relativity and the special theory of relativity are different. In this short animated video, we give a simple explanation of time dilation and Einstein’s theory of relativity and also explain how time slows down in a moving vehicle!

                    In insteens thought, at the same time, same velocity, there is defference in length... In this case,my point of view, the length is correct... The time is also correct..

                                Time dilation is a fudge factor used to balance mathematical equation. Non material concepts can’t be stretched, shrunk or anything else done to them because they do not possess any alterable properties.

                                  Even if your travelling at the speed of light and the clock that you was looking at has stopped... doesn't mean time has stopped for you... look down at your watch.. its still ticking at the same speed as the one where you started from albeit the light will never catch up with you... if you travel back to it you will see it spinning at the speed of light? When you return the time will be right again...? I think time is always relative to your present self and only changes for the observer?

                                      7:24 "Stretching the duration of a second" – if it's in a vacuum chamber dropping towards the earth, would the beam be curved up, or would it still move in a straight line? Turn on a laser and drop it will the beam curve into space?

                                      Seems like the yellow dot (light beam) will still reflect at the same rate, but faster in a longer distance – which light cannot move faster or slower in space. So time moves slower or faster but light speed remains constant. This appears misleading concerning time, speed and distance in regards to viewpoint (or a light beam).

                                            THE ULTIMATE UNIFICATION OF PHYSICS/PHYSICAL EXPERIENCE HAS BEEN MATHEMATICALLY PROVEN:

                                            The balance of being AND EXPERIENCE is essential in what is the ultimate UNIFICATION of physics/physical experience. It is a very great law of physics that the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. (THOUGHTS ARE INVISIBLE.) BALANCE AND completeness go hand in hand.

                                            The SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. This is a very great truth in physics. The ultimate unification of physics/physical experience combines, BALANCES, and includes opposites.

                                            Very importantly, outer "space" involves full inertia; AND it is FULLY INVISIBLE AND black. THINK about it ALL. Piece it all together. We always begin with typical, common, or ordinary experience when establishing physical fundamentals or laws. Importantly, more explains more in physics; AND less explains less.

                                            The additional (fourth) spatial dimension is known to mathematically unify Einstein's equations (regarding gravity) with Maxwell's equations (as they describe electromagnetism). ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 is DIRECTLY AND FUNDAMENTALLY derived from F=ma. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, and describes what is possible/potential AND actual IN BALANCE. Now, consider what is invisible AND VISIBLE SPACE in fundamental equilibrium AND BALANCE. EXCELLENT. So, gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED IN AND OUT of SPACE AND TIME; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Magnificent.

                                            A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY.

                                            Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The stars AND PLANETS are POINTS in the night sky. Now, get a good LOOK at what is the black space of THE EYE. GREAT. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, Einstein's equations predict that SPACE is contracting OR expanding IN AND WITH TIME. F=ma AND E=mc2 CLEARLY PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY. Moreover, time dilation also ULTIMATELY proves that GRAVITY IS ELECTROMAGNETISM/ENERGY. Galaxies are basically FLAT, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The birth AND death of stars is thus basically visible AND understood. Stellar clustering ALSO proves that ELECTROMAGNETISM/ENERGY IS GRAVITY. Clearly, the supergiant stars prove that ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Stars as closer together AND farther apart make galaxies much better understood. GRAVITATIONAL FORCE/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This also explains the cosmological redshift AND the "black hole(s)". "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED ELECTROMAGNETIC/GRAVITATIONAL FORCE/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM ENERGY IS GRAVITY. GREAT. F=ma AND E=mc2 PROVE that ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Absolutely ingenious !!! POINTS are points. I have explained why HALF of the galaxies are "dead" or inert. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY.

                                            Dream experience is possible/potential AND actual IN BALANCE. Dream experience is/involves true/real QUANTUM GRAVITY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, there is no outsmarting the genius of dreams. MOST IMPORTANTLY, in dreams, BODILY/VISUAL experience is invisible AND VISIBLE IN BALANCE. (THE EYE is ALSO the body.) Dream experience is CLEARLY that of the MIDDLE DISTANCE in/of SPACE. Great !!! Dream experience GROWS/INCREASES.

                                            "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/AS what is BALANCED ELECTROMAGNETIC/GRAVITATIONAL FORCE/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 prove that ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THEREFORE, the stars AND PLANETS are POINTS in the night sky; AND objects fall at the SAME RATE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. THINK about it. GRAVITATIONAL FORCE/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. GREAT !!! BALANCE AND completeness go hand in hand.

                                            THE PLANETS are not "falling" in "curved SPACE" in RELATION to what is THE SUN. This is nonsense. The rotation of the Moon MATCHES it's revolution. THEREFORE, it is PROVEN that gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ACCORDINGLY, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent WITH/AS F=ma, E=mc2, AND what is PERPETUAL MOTION; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! GRAVITATIONAL FORCE/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. ALL of SPACE is NECESSARILY ELECTROMAGNETIC/GRAVITATIONAL (IN BALANCE), AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. F=ma and E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS GRAVITY IS ELECTROMAGNETISM/ENERGY.

                                                  Its easy to understand if you think like this..
                                                  1. Time moves in linear direction (simple fact)
                                                  2. How much space you can cover/experience if you move 100mph compare to 20mph.. that means how much data you store per second is also different. Thats it!

                                                  And my opinion on how a pro gamers so good is also related to this theory.. lets say they suddenly face their enemy, their time moves slower that each second is divided into 10-20 parts (thats why they always lived and the enemy died) while other people's second divided only 1-5 parts.. like if it helps..thanks

                                                  What if Einstein were to travel towards the clock? The time on the clock would have doubled for him. Time doesn't stop, its consistent for you as you'd age with the same rate.

                                                    the faster you move through space, the slower you move through time, so what is meant with this? does this mean that if i travel faster 1 second becomes 1.05 seconds long?

                                                      I dont understand either why the speed of light would be an exception, if an electromagnetic wave passes a planet which is moving the opposite direction at lets say 300.000 m/s, then with respect to the planet, the electromagnetic wave is going 300.092.458 m/s, right?

                                                      I don't understand how time would stop if you're going at the speed of light, the only reason why the clocks hand wouldn't be moving whilst your going at the speed of light is because you're moving at the same speed as light is therefore not reaching you and appearing as if time had frozen.

                                                        So what about the clock you're heading towards? Wouldn't it appear to go faster?

                                                                          When person falling while carrying 2 plates which bounces a photon every second, the photon will move upwards as plates moves downloads, so triangle is not downwards, it's upwards. If it's same photon, it will hit upper barrier eventually, if new photon gets generated every second, it will appear to hit the other side little upwards. In both cases, horizontal distance travelled by photon remains the same.
                                                                          Relative motion is understandable, but relative time is confusing.
