Time is a concept that has puzzled humanity for centuries. Across different civilizations, cultures and eras, time has been studied by a plethora of individuals; scientists, philosophers, artists, and even priests. Despite the fact that no one has been able to explain, comprehend, or evaluate what time is exactly, physicists constantly try to do so in their own way. In the field of physics, time is described as a dimension. This dimension is a fundamental part of our existence, the universe, and everything that surrounds us. It quantifies the duration of events, and measures changes in our environment. In fact, the word change is the core concept of time in physics. Change – from the distance you walk to the movement of a clock arm – is how time is detected, measured, and understood. It takes an extremely abstract, loose concept, and turns it into something empirical. When looking at breathtaking scenery, or encapsulated in a highly emotional moment, we often deploy the phrase “as if time has stopped”. While life certainly does feel so in some moments, we still understand that time, in fact, has still passed by because we notice the changes: the sky has turned a bit darker, the pedestrian who had waited at the crosswalk is on the other side, and a watch tells us 36 seconds have passed. Though this is a universal scientific understanding of time, the exact perimeter to which scientists describe time differs amongst various subfields of physics. Quantum mechanics view time as an entirely static parameter, a rigid system to measure when events happen. On the other hand, relativity sees time as a flowing, flexible concept. Time warps depending on factors like speed and gravitational fields, as explained in Einstein's theory of relativity.
