For all intents and purposes, now is impossible because it is not - TopicsExpress



          

For all intents and purposes, now is impossible because it is not apprehensible by the senses. Our bodies are not as amazing as one might think when one compares the speed of light to the speed of nerve impulses. ❝Even if nerve impulses propagate fast along nerve fibers, their traveling times are still much slower than the speed of light. Although there are variations for different types of nerves and for different people, the speed is around 60 feet per second. That is, nerve impulses travel about 1 foot in sixteen milliseconds. (A millisecond is one thousandth of a second.) For comparison, light travels 2,980 miles in the same amount of time, a little more than the driving distance from New York to San Diego.❞ pbs.org/wgbh/nova/blogs/physics/2014/06/there-is-no-now/
