According to Hermann Minkowski, Albert Einstein’s mathematics teacher, space and time make up the same reality. In this regard, he also stated that independently, both space and time would fade into obscurity. This led to the idea that reality exists in both space and time together, with space providing the three dimensions of height, width and depth while time contributes the fourth dimension. Thus, time cannot exist independently but exists as the Space-time continuum.
Experiments have been performed to further explain this theory and to confirm the non-existence of time or, at least, disapprove how we currently understand it. The double slit experiment showed an individual bit of matter such as a photon passing through both slots at the same time, passing individually through both slits and not passing in any of the slots, exhibiting an “interference pattern.” A similar experiment based on the double slit experiment and known as the delayed choice experiment further disapproved the existence of time as we know it. It confirmed that the definition of time affects the movement of bits of matter from one place to the other.
For instance, an electron shot towards a larger rounded piece of matter would move through two different paths (left or right/ up or down) at the same time. This phenomenon is thus determined by the observer who would make a choice of which path the electron followed based on the definition and interpretation of time. However, the electron moved similarly to the double slit experiment.
