Relativity is a profound science. In the picture (top left) we see
how the presence of mass distorts the otherwise linear fabric of space. And in the picture (top right) we can see by using this "Fish eye" lens analogy - just how mind blowing space-time distortion can be. So mind blowing in fact that the area under the power of the lens has become completely detatched from any reality beyond its grip. The lens comparison is not a trick, its how things really are in "Space-time/gravity" vortices - and in these pages I'm trying desperately to understand the full implications of the above effects.
Below is a simple diagram to explain the essence of relativity
