Normally light travels in a straight line. However, it has been demonstrated that gravity can bend the path of light.
how can we say light does not need light to travel
Light Rays travel in straight paths as transverse waves. It needs no medium to travel along.
no if an object is OPAQUE then light can't travel through it (unless it has a hole in it)
Light will not travel through an opaque sponge.

. What do you mean? What is they?
how can we say light does not need light to travel
Normally, the answer to that kind of question would depend on what you call "low".In the case of light, however, probably nobody would call it a 'low' speed, becauseit's physically impossible for anything in creation to travel faster than light in a vacuum. It is possible for things to travel faster than light does in other media, but it's not exactly common, and it's still very much on the "fast" end of the scale.
Light will not travel into silver.
Light can travel in a vacuum or in any transparent material
There is no way to travel at the speed of light.
