Can a 2 dimensional object Exist?

It isn’t possible to have a truly 2D object in our space-time – the energy required to make it exist would defacto collapse it into a black hole. That said, black hole event horizons may be 2D structures – though the fact they are wrapped around a sphere/torus may cause that to be disputed.

Why are shadows always black?

Shadows most often appear black because the visible light cannot make its way past the obstruction, if there is no light falling on an object then it will be black as there is no light to reflect. … As to why black is the absence of light, it just is and we have to accept that.
