  • 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!

      First of all lets think there is no time so speed cannot be calucated is time if we are standing at or our earth is on 265 day and we want to go on 300 so we tooked a space sheep and tried to go forword of earth with particles of earth and after days the particles will grow or fungus or it will increase while moving forward of earth the then the time we move to 300 day and wating for earth to arrive....is it possible think once again moving in space is quiet big what will the influences and problem will we go to another field because of forces...look in another way.. subscribe my channel

          If he moved at the speed of light, the clock tower would disappear because the photons would never reach his eyes.

            Time dilation is when you have your pupils dilated and you can't tell time. See? ( ^ _ ^ )

              Of course the clock would seem to freeze because I’m traveling with the speed of light and the light of the clock will never reach me

                @Science ABC why would Einstein see that the time in the tower would slow down? Didn't we just determine that the speed of light is the same on all reference points? So it doesn't matter if you are moving towards or away from the source of light it should come to you at the same speed.

                        If he’s receding at the speed of light, the clock tower disappears instantly. Measured against infinity everything becomes nothing. Everything, that is except the observer. Both time and space dissolves practically. A million years will flash away like a nanosecond. Time is an illusion. You think it’s there, well from our perspective, it’s there, but in the grand scheme of everything, it’s not really there, including everything we see. The earth and all the universe don’t even amount to a speck.

                          If they aged 7 years in 1 hour on planet X then time cannot be a fixed universal rule it can vary. If you lived on planet X and sent a beam of light to earth what would change? Time and space are not the same. We live in space not time. If time changes with speed or what planet your on then time is only at our side. Not part of space.

                              The speed of light is almost 300.000 km/s, instead of 300.000 m/s

                                ant to know if we travel with a warp drive can we dilate the time ?
                                Time dilation work with speed of light but if we are traveling faster than speed of light but through the warp drive what will happen ?

                                                  Hello Science ABC ... I have a question that if a body is accelerated by gravity which is just a curvature in space-time instead of a force then if the body due to gravity approaches the speed of light, the increase in mass of the body will have no effect on decreasing its speed and even greater mass would cause greater gravitational pull and the body could surpass speed of light ??? what say?

                                                    its simple... if you are not enjoying something (school, work, etc.) time goes slowly
                                                    but if you enjoy it, time flies really fast 😀

What is it mean anyway.? My god you are the greatest... smartest.... strongest i believe in you with all my heart and soul

Lets ignore all scientific facts of continuincity of the soul all over those years spread out all around the world and keep saying that theres nothing else beside this phisical world we think we know....

                                                                        • עוז מגר

There are pepole who try to solve the riddle and there are who ignore and sleep on their nose instead finding way out.... One thing is for sure....all of us skeptic or not will born into another riality just like the day we got out of the womb in our birth
