Well, to see is what people actually do, when they look into the night sky.

With a telescope we could look further, but that was also based on human 
perception of light.

Today we have other means and can 'see' more or less the entire em-spectrum.

But our methaphysical intuition is based on the visual impressions of 
our ancestors, because that is how mainstream physics works.

Therefore I refer to seeing in connection with cosmological modells, 
because our intuition is based on light and vision.

To include non-em waves or other frequencies into cosmology would allow 
other intuitions, but that is something, which our mainstream does not like.
