In space, light travels at speeds of 299,792,458 meters per second (about 186,000 miles per second). This weird value is quite voluntary and it’s how we take the second and one meter key in 1975 conventions.
Light it, as far as we can tell, is always moving at the same speed in space – here, in the Andromeda galaxy and the farthest reaches of the visible universe. And when we think of it as the speed of light, it is cropped up in so many places in physics that it can only be considered to be related to electromagnetism.
This is the speed at which the massless particle moves and no specific value can be transmitted to our universe faster than this specific value. So why this value, Why constant? And why does it pop up everywhere? We still don’t have a final answer. It’s one of those things we don’t know, we don’t know that hint in the complex machinery of the universe … hopefully just hidden behind a screen that we’re slipping through.
Or historically, there are many theories about how fast light travel – but the first serious experimental evidence was that it was fast but limited. The speed of light is being limited. After that initial guess, the value became more modified, but the moment of change in the game was due to Maxwell’s theory of electromagnetism. In this theory, light is understood as an electromagnetic wave and its motion can be considered as two more static. In this formula, ε0 represents the electric constant and μ0 the magnetic constant. Both depend on other constants in the universe such as the initial charge and the finite structure constant.
Not to sound too much like a conspiracy theorist, but it’s “It’s all connected!” On a basic level, there are indications that all the features of the universe are connected to each other and this is why we see these quantities popping up in terms of different physical things. Based on what we still know, one day it was possible to find our complete physical understanding in a single model: the theory of all things. We do not know if the universe would be possible with somewhat different values, or if these could be the only possible values, then the search for the answer continues. And uninterrupted C can literally illuminate the way for humanity to find it.
