there must have been expereimetnts on sample lenght a wire and a fiber that prove the data transmission speed of one is n times faster the other? How fast is it? this is
in reference to the below question where public talk of many theories of current and prove that electric current speed is 75 percent of light which i felt is not that big a differnce for change in technolgy.i think it should be drastic difference for such a technological revolution adn replacement of the older system.I WOULD LIKE TO KNOW REAL DATA OF SPEED OF CURRENT

I think animals are the cutest things in the world and people mock my excitement towards them. I like to stop the car and talk to the deer and everyone screams at me to keep driving...but I just want to say hello.

They say I'm obsessed...I think they're heartless. What do you think?
