his friend Rick, however, decides to sit back and relax and enjoy the lazy winters back at home. Which means, if you shine a beam of light from a car traveling at 50kmph then the speed of light will not be c+50kmph.Īllen has planned a short interstellar trip this upcoming winter vacation. It was also concluded that whatever reference frame you are in, the speed of light is constant. Maxwell through the basic laws of electricity and magnetism derived the speed of the light. If you start accelerating than obviously, you can feel the effects of acceleration. Provided!!!! there is no acceleration and the airplane travels at a constant velocity. If you spill coffee on the airplane it will fall the same way on your lap like it would do on your sofa in your living room.

When we travel on an airplane we actually can’t tell whether we are moving at 700 kmph unless we look outside and see the clouds and the ground moving away.Īnd all the experiments we perform on the airplane will be agreed with the experiments performed on the ground. The only motion that matters is relative motion between objects.Īnd this is pretty much understandable. Indirectly, this tells us that there is no such thing as absolute motion: if there is no physical experiment which can distinguish between an experimenter moving at (absolute) constant speed or sitting at (absolute) rest, the term ‘absolute motion’ has no meaning. In other words, we all play by the same physical rules, whether we are ‘moving’ or ‘standing still’. “The laws of physics (mechanics) are the same for any observer In general relativity, clocks that are near a strong gravitational field run slower than clocks in a weaker gravitational field.īefore we go any deeper into time dilation, we need to clear our concepts on Newtonian Relativity and Electromagnetism.Īccording to Newton, velocities are relative to one another. This effect does not come from workings of the clocks, but from the nature of spacetime.Ĭase #2: the observers may be in positions with different gravitational masses. In Albert Einstein’s theories of relativity, there are two types of time dilation:Ĭase #1: In special relativity, clocks that are moving run slower according to a stationary observer’s clock. This concept first originated from Einsteins Theory of Relativity.
