If nothing is faster than light, how did the dark get there first? O. o

Nothing is faster than light. Dark is the absence of light, or indeed anything at all.  Darkness came before light, so light had to be created to get there. It's like turning on s flashlight in a dark room: the darkness is already there, and an outside source (you/the flashlight) needs to create light.

Explanation: Nothing is faster than light lighting is very fast.

the ima (higher than 1m) will be greater than the ima with the height of 1m.
