It should be "the smaller the speed relative to the speed of light, the closer it should be to Newton mechanics"...and this way of stating it makes it clearer why the effects of relativity would be more conspicuous if the speed of light were lower (although as this page points out, the idea of changing a dimensionful constant like the speed of light may not be very meaningful).asdf1 said:the smaller the speed, the closer it should be to Newton mechanics...
The speed of light is a fundamental constant in physics, denoted by the letter c. In a vacuum, it is approximately 299,792,458 meters per second.
If the speed of light was slower, it would have a significant impact on the laws of physics. Time and space would be affected, and the universe as we know it would look very different.
A slower speed of light would have a minimal impact on our daily lives. It would only be noticeable in extreme cases, such as when traveling at speeds close to the speed of light or in highly precise scientific experiments.
Currently, it is believed that the speed of light is a constant and cannot be changed. However, there are some theories and experiments that suggest it may have been different in the early universe.
If the speed of light was slower, it would affect the structure and expansion of the universe. It could also change the fundamental forces that govern the behavior of particles and matter, leading to a very different universe than the one we currently observe.
