经验告诉我们，要超过风速或声速是不难做到的。所以说，能不能超越，要看输

Experience tells us that we must exceed the velocity or speed of sound is not hard to do. So, you can not go beyond, depending on the input information which is light band. For the speed of light 400-760 nanometer band (though we can not measure it) can not be surpassed. why? Because the human species is only able to "decode" this band by the carrier of information carried by the light, and then converts it into the universe. Any light propagation speed information exceeds the speed of light this band, we will not see. Knowing this will help us to rethink the "black hole" of such objects.

Experience tells us that it is not difficult to exceed wind speed or sound speed. So, can you go beyond, depending on which band of light information is entered. For the 400-760 nm band the speed of light (although we cannot measure it) cannot be exceeded. Why? Because the human species can only "decode" the information carried by the carrier light of this band and convert it into everything in the universe. Any light information travels faster than the speed of light in this band, and we can't see it. Understanding this will help us reacquaint ourselves with the object of a "black hole".

Experience tells us that it is not difficult to exceed the speed of wind or sound. So, whether we can surpass it depends on which band of optical information is input. For the 400-760 nm band, the speed of light (though we can't measure it) can't be exceeded. Why? Because the human species can only "decode" the information carried by the carrier light in this band, and then convert it into all things in the universe. If the propagation speed of any optical information exceeds the speed of light in this band, we will not see it. Understanding this will help us to understand the black hole again.
