**Einstein’s theory of special relativity** ** ****05/23/16**

*Why can you not go faster than the speed of light?*

This is one question that many great thinker have pondered ever since Maxwell demonstrated that the speed of light is fixed for every reference frame. How can it be possible to accommodate newtonian Mechanics, which states that all velocities are in reference to one another, with Electrodynamics, which states that there is an absolute limit for light? One great thinker who thought about this was known as **Albert Einstein**. After a considerable amount of thinking, he came up with his most brilliant idea in 1905. By taking the above two contradictions as postulates, he came upon to an amazing epiphany. **All time is relative**. Let us see how this works symbolically. Einstein came up with an equation for **Time dilation** t’=t1-v2c2, with t’being the shift in time, tbeing the change in time, vbeing the velocity, and cbeing the speed of light. If one were to have a velocity, then they would experience time as going slower around them. In this special theory of relativity, Einstein derived his most famous expression, E=mc2, which relates the mass of an object to the energy. What is even more amazing is that this shows that mass is directly proportional to energy, so if energy increase, **mass increases!** Furthermore, when an object approaches the speed of light, it’s mass increases so much that it becomes **impossible to accelerate**, therefore nothing can go past the speed of light.
