Why doesn't light go faster than it does?

AI Thread Summary
Light does not travel faster than its established speed due to the fundamental properties of permittivity and permeability, which govern electromagnetic wave propagation. Despite having no mass, light's speed is constrained by the principles of relativity, making it a special case in physics. Other forces, including gravity and nuclear interactions, also propagate at this maximum speed. The discussion emphasizes that no wave equation can define a scenario where the speed of propagation is infinite. Thus, the speed of light remains a constant limit in the universe.

If it has no mass, what stops it from going arbitrarily fast? Why doesn't it have infinite speed?
 
Science news on Phys.org
Permittivity & permeability properties determine e.m. wave speed.
 
Check out [post=1556816]this excellent post[/post] on the subject by rbj.

Try writing down a wave equation where the speed of propagation is infinite :p
 
light is a special case .no mater what speed of light cannot be more than what it is.its a relativity concept.

Actually, it's not just light - as rbj points out in the post I linked to E&M, gravity, nuclear interactions, etc. all travel at the speed of light.
