Einstein realized that time, space, matter, and energy were interchangeable. This single idea deposed the normal world of the five senses with its claim that nothing we see, hear, taste, touch, and smell is reliable. You can do your own visualization to prove this fact to yourself. See yourself sitting on a train moving down the tracks. You look out the window and notice that a second train is traveling beside you on a second, parallel track. This second train isn’t moving forward, however, so according to your eyes, it must be standing still. But your eyes are lying, since in reality your train and the second train are moving at the same speed relative to the platform. Mentally, we all adjust to the lies our senses tell us. We adjust to the lie that the sun rises in the east and sets in the west. As a fire truck whizzes past, its siren rises in pitch as it approaches and decreases in pitch as it races off into the distance. But mentally we know that the siren’s sound hasn’t changed. The rising and falling was a lie told by our ears.
