In classical Newtonian physics, space and time are absolute quantities. Hence, space and time can be treated independently and discussed separately. With his theory of relativity, Einstein proved that space and time are dependent and must not be treated separately. Einstein proved this idea through time dilation and length contraction formula. He proved time dilation and length contraction formula through some thought experiments. But there is no real evidence of these formulas. Here in this article I will use my thought experiments to demonstrate that length contraction formula is wrong.
