**Here's how you contain infinity within a unity**

We're all familiar with the concept of optical reflection. When a beam of light hits a mirrored surface, it gets reflected right?. And we've all seen that crazy situation where, if you set up two mirrored surfaces facing each other, you can get them to reflect each other out to infinity.

Well, here's a concept called

**spatial reflection**. If you create a perfect hollow sphere - and it has to be perfect or this doesn't work - and coat the inner surface with a material that reflects space and nothing else, then the space contained within the sphere gets reflected out in all directions to infinity. In this way, just like light and optical reflectors traps a finite beam of light and reflects that beam of light out to infinity in both directions, space and spatial reflectors traps a finite space bubble within a sphere and reflects that space bubble out in all directions to infinity.

If you have the technology to build such a sphere, and know how to coat it's inner surface with a spatially reflecting material, you can contain an infinite space bubble within a finite sphere.

Of course, when you're inside the sphere, space appears to be infinite in all directions - and in fact it is. However, when you're outside the sphere, it's obvious the sphere is actually only the size of, say, a snooker ball.

Are you science geeks sure you're not trapped within such a sphere?
