How real is reality?

You probably see the world around you in 3 dimensions - up/down, side/other side and back/front. Time is the 4th dimension as objects move in 3 dimensions.

That all seems pretty solid and, well, real - right?

Well not quite - it seems we can only perceive four when in fact there are believed to be 10.

Once you start to read into the string theory behind this you start to realise the universe is so much more complex then we understand and our reality is just a tiny piece of it.

If that doesn't bake your noodle then I don't know what will.

All that stuff about parallel universes etc has some basis in fact after all.

The next thing you know there will be proof that time is non linear and our perception of it is all that is making it so.

What, you didn't know....?
