This is my second (easy) riddle:
You can see me but you see through me.
I can fill the room but I will vanish as soon as nobody creates me.
I transport energy but I am not sure if I am made of physical matter.
Nobody is faster than me but I cannot drive on regular streets.
I do not need anything to survive but there are things that can stop me.
I am information but I can overwrite myself.
Who am I?
Straight-forward answer:
Light
You can see me but you see through me.
We can see through he medium light passes through and see the light reflected off objects.
I can fill the room but I will vanish as soon as nobody creates me.
A brightly lit room can get dark as soon as the light source is cut off.
I transport energy but I am not sure if I am made of physical matter.
The basic composition of light, photons, is not tangible matter but transport energy.
Nobody is faster than me but I cannot drive on regular streets.
Nothing beats speed of light but as it’s not a vehicle in itself.
I do not need anything to survive but there are things that can stop me.
Light can be obstructed by an object
I am information but I can overwrite myself.
Light can be used to pass information but it can be disrupted through interference.
