We may think the speed of light is super-fast when compared to our known speeds, but 299 792 kilometers per second, in a Galactic scale, it’s actually pretty slow. At the speed of light, you would take around 45 minutes to go from the Sun to Jupiter.
The special theory of relativity, written by Albert Einstein, states that the closer you get to the speed of light, the slower the time passes by, and when you get to the speed of light, the time would actually stop, and if we surpass it, we would actually be going back in time.
Other thing we should keep in mind, is that nothing with mass can in theory reach the speed of light, since when something is coming close to it, the inertia increases, and in the case of an object with mass, it would slow down.
But, if an object has no mass, as Joe Scott, host of “Answers With Joe” explains, it would travel all the time at the speed of light, and wouldn’t be able to run any slower.
But some physicists have suggested that another cosmic factor can influence the speed of light, the quantum vacuum fluctuation. This theory is based on the assumption that empty spaces on the Universe, aren’t actually empty, they are instead filled with particles that are constantly changing between existent and non-existent states.
And based on that, Quantum fluctuations can in theory actually slow down the speed of light. Of course, this doesn’t answer to the most important question of all: what if the speed of light doesn’t actually have a limit, and is infinite?
