Is light finite? is it really a electro/mag wave through empty space? what is this is a early error?

Therefore extrapolating backwards in time from light does not give a accurate age. Light is likely instant originally but is now interfered with a bit.

the quality of bbc doumentaries puts to shame my public television network. I'm just a cow milked by government, the TV license is super expensive here, we only get satisfied idiots lecturing us.
