Light is a kind of electro-magnetci wave... ALL electro-magnetic waves travel at "the speed of light".... this includes the visible light, ultra violet and infra-red light, micro-waves, x rays, gamma rays and so on... Gravity waves also travel at that speed. Yes, gravity also travels (strange though). just imagine a huge star going BOOOM and the effect it will have. apparently it'll send gravity waves in every direction. Many sub-atomic particles also aproach the speed of light and behave like waves and paricles at hte same time.. Any matter that travels (really really fast) gains (significant if fast enough) mass, gets shorter and time slows down for it.

Electromagnetic waves (which include visible light, infrared, ultraviolet, x-rays, gamma rays, microwaves, and radio waves) travel at the "speed of light". This would be true of any wave that can travel through a vaccuum without a medium.
Gravity waves which transmit a "gravitational field" are assumed to travel at the speed of light, but have yet to be detected.
All other known waves require a medium to be transmitted and so travel slower than light.

Light waves travel at the speed of light.

None. All waves that do not require a medium to pass through travel at the speed of light.

Actually the speed related to the medium that it scattered on it I think you mean the speed of light in vacuum but electromagnetic waves can do what you want cause they have the same nature I mean modern physics proved that light is electromagnetic wave!!

Thought waves can exceed the speed of light. In one second i can be thinking of earth and the next i will be thinking of proxima centauri. It will take light more than 3 YEARS to do that. Thought is faster than light!

all electromagnetic waves (light is A kind of electromagnetic wave)
also neutrinos. but at these speeds, matter IS energy, so I guess they're a kind of electromagnetic wave too
(propagation of gravity is supposed to be instanteneous, because it's a force)

you're confusing diverse innovations and a similar notice used as an adjective here, yet with diverse meanings. "dark", on your storage occasion, is in simple terms the absence of sunshine. dark would not pass - mild leaves, and the absence of sunshine continues to be. it particularly is like shutting off the water on your bathe. you do not unexpectedly get hit with a team of non-water. The water stops flowing, is all. "dark rely" is in simple terms rely that we will not stumble upon. Scientists CAN degree the cost of products as they conflict by area, and might estimate their mass. in addition they comprehend the guidelines of action that each and every physique mass might desire to shop on with, be they something the size of a bagel, or something the size of the Andromeda galaxy. the celebs and galaxies that we are in a position to confirm do not shop on with the guidelines wisely - the stuff that we are in a position to confirm would not have sufficient mass to pass the way it does. They pass as though there grew to become into lots greater mass in contact in a roundabout way. So scientists and physicists desperate that there might desire to be greater mass available, and that they have given the call "dark rely" to this mass.

electromagnetics waves in the void of the univers ie not in matter or air, if you considers photons as waves, photons can also
