The Implications of Light Speed

Essentially, we and all things are moving through the spatial dimensions as well as the dimension of time cumulatively at the speed of light. Moving through time takes up the majority of this energy which is why we as humans aren’t perceiving ourselves as hurdling through space at near light speeds. A massless photon however has all of its energy devoted to movement through space at 180,000 miles per second. This leaves none of its energy available to allow photons to move through time thus, light never ages. Remarkably, light originating from the big bang is perpetually the same age as it was 13.7 billion years ago.

All other matter with mass, at an absolute state of rest, will be channeling its energy entirely to the flow of time. Once a particle begins to move through space, that energy begins to flow less through time and more through space. This means that the particle, being, or what have you, will begin to age less relative to other stationary objects. Light speed (671 million MPH) is the cosmic speed limit due to the fact that energy equals mass times the speed of light (E=MC^2). Theoretically,in order for an object with mass to move through space at the speed of light, its energy would have to be infinite.

So what can we derive from all this? The possibility of time travel; let’s take it to the extreme. Say you decide to venture out to the closest black hole to our galaxy, V4641 Sgr  located in the Sagittarius arm of the Milky Way. With the immense amount of mass and gravitational strain placed on anything within the black hole’s vicinity, time is virtually brought to a standstill. If you were to hover at a ‘safe’ distance near the event horizon for about an hour relative to you, upon returning to Earth you’d find that millennia had passed during your hour long rendezvous with V4642 Sgr. As far as modern day cosmology goes, this would be a one way trip. There is no known way to travel backwards in time. Your only hope of returning would be banking on the research of future physicists leading them to a way to send you back. Would you be willing to take the risk?
