| ID:chicag243 | Light has finite energy, weight, speed; however, other objects need infinity energy to reach speed as fast as light. Why is light so special? | |

| ANo.1 | The difficulty here is the fact that light, while having finite energy and speed, does not have finite weight. In fact, it lacks mass entirely. Light, rather than being a physical object, is an emission of energy particles, known as photons. These particles, which behave more like waves than standard particles, are a form of energy, rather than matter. Since they have no physical substance, they are exempt from the laws that require infinite energy to meet or surpass the maximum speed. Objects composed of matter, require an exponentially (or more) increasing amount of energy to accelerate to faster and faster speeds. With light speed currently being perceived as an infinite velocity, the theory is such that infinite energy would be required to accelerate any matter to that speed. There are, of course, theoretical ways around that, but that would be a little beyond the scope of your question. This in turn would raise questions of time-dilation and Einsteinian relativity. Hope this helps! |
