I was recently out walking in the beautiful countryside of Gwehelog, in Wales, when I noticed a wonderful rainbow arching across the valley.
I stood to admire the vivid colours, and held my gaze for a while. Then all of a sudden I noticed the patch of rainbow I was looking at starting to vanish!
I played with this most peculiar phenomenon by making the rainbow hide and reappear at will. I then noticed that the rainbow could be made invisible for quite some time, and this got me thinking what else am I missing?
If the huge, bright rainbow can vanish when looking at it, what else could be there, but unseen?
I have often seen glowing layers around my daughter in the photograph I took of her on the beach (OK, it's mud) earlier this year. This could just be a quirk of the lighting and how the camera processed the image, however others I ask to look at it dismiss my exclamations.
What else may we not see, hear or feel? Should we only be bound to our physical senses, or should we learn to seek other sensorial experiences?
There is a lot we don't understand about the universe, so rather than thinking we know it all, go out and keep exploring!
