It was not the first time since I disclosed astronomical, though it is not at all left me so indifferent that I continue to think again.
This afternoon a non-blind visited the show and it was a really good dialogue.
With the cosmic abyss we are in contact only through the light, but it is often forgotten that visible light is only a small part of the electromagnetic waves coming from space and so, in front of the telescope we see displayed in the exhibition: "Yes, we are all blind to the microwave, all in the same way, we are all on the same starting line."
And from there the comparison is continued on other things that a non-sighted grasp certainly better than many other visitors: the note of the tuning fork clean and bright as the band H alpha hydrogen, the Doppler variation of his tone, the mental journey among billions of galaxies moving away ...
I'm still traveling.
Thanks:)
