Since light travels at the speed of light (duh!), let’s imagine a disembodied observer (pure mind with no mass) traveling at the speed of light. Einstein’s equations would predict that from light’s point of view (the point of view of the disembodied observer), it travels no distance and takes zero time to do so. This points to something very strange indeed about light. Whatever light is, it seems to exist in a realm where there is no before and no after. There is only now.
