Einstein first introduced this term in the year 1905. It is a theorem that deals with the structure of space-time. Einstein explained this theory based on two postulates –
The laws of physics are same for all irrespective of the velocity of the observer.Speed of light is always constant regardless the motion of light source or the motion of the observer.
This is the theory which laid the foundation to time travel. According to Einstein, the rate at which time tics decreases with the increase the velocity of the person. But this is hard to notice as the decrease in the time is relatively very low when compared to the increase in time. So, it can be assumed that if you can equal the velocity of light, you will be in a situation where time is still. This phenomenon is called Time Dilation. There are other surprising consequences of this theory such as –
Relativity of simultaneity – two actions, simultaneous for one person may not be simultaneous for another person in relative motion.Length Shrinking: Objects are measured and appeared to be shorter in the direction that they are moving with respect to the observer.Mass – Energy Equivalence: Study of relativity lead to a one of the greatest inventions i.e., E = mc2 where E is Energy, m stands for mass and c for velocity of light. Many scientists observed that the mass of the object is increased with the velocity but never knew how to calculate it. This equations is the answer to their problem which explains that the increased relativistic weight of the object is equal to the kinetic energydivided by the square of speed of light.
General Theory Of Relativity:
General Relativity theory developed by Einstein in the year 1907-1915 states that being at rest in the gravitational field and accelerating are identical physically. For example, an observer can see ball fall the same way on the rocket and on Earth. This is due to the acceleration of the rocket which is equal to 9.8 m/s2. This theory relates Newton’s gravitational theory and special relativity.
