The Arrow of Time is an compelling metaphor. It describes the "one-way direction" of time. It was only in 1927 that it was developed by Arthur Eddington. It remains an unsolved general physics question. The "one-way direction" means that that time is asymmetrical. If time were symmetrical then a video of real events would seem as realistic whether played forwards or backwards.
Wikipedia tells me that physical processes at the microscopic level are believed to be either entirely or mostly time-symmetric: if the direction of time were to reverse, the theoretical statements that describe them would remain true. Yet at the macroscopic level it often appears that this is not the case: there is an obvious direction (or flow) of time.
For me, the part that is fascinating is how each of us perceive time. Our perception of time is as a continuous movement from the known past to the unknown future.
nd exceptions? This article from the BBC talks about people who have experienced time stopping - such experiences can be part of epilepsies or strokes.
Another area that is under scrutiny is the experience of time seeming to stand still. This most commonly happens with something like "a beautiful sunset, a mesmerizing song or a moving piece of artwork is able to fully captivate our attention. And for that brief period, time seems to stand still."
That's the presence of awe. According to Melanie Rudd, Kathleen Vohs and Jennifer Aaker in a huffiest.com article HERE, "there are two things needed for someone to have a true awe experience: perceptual vastness -- you need to perceive that you've encountered something vast in number, size, scope, complexity or social bearing -- and a need for accommodation. You need to feel that you have to revise or update the way you think about or understand the world. While anything you encounter in daily life can evoke a sense of awe by meeting these two requirements, it is often artistic, musical, natural and spiritual elements that elicit such responses."
So then it would likely be awe that would explain Carl Sagan's and Brian Cox's mesmerizing presence in their documentaries. |
