Never mind "touch" all atoms in the universe overlap.
They don't have "edges".

Note that the everday concept of touch (i.e the hard boundaries of two objects exist at the same location) makes no sense at the atomic level because atoms don't have hard boundaries. Atoms are not really solid spheres. They are fuzzy quantum probability clouds filled with electrons spread out into waving cloud-like shapes called "orbitals".

How do I know that my eyes perceive colours exactly the same as yours ? For all i know your orange might be my green ?You don't. No way to compare subjective experience, but there are some people that see more colour than typical, sort of the opposite of being colour blind. They see patterns in flowers that might appear white to me. They get offended that the crayon box never seems to be anywhere near complete.
Do both eyes see colours exactly the same ?I think one would notice if otherwise, so barring health issues, yes.
Does the colour of eyes have any effect on colour perception ?No
Will I still perceive colours the same when I'm 80 like i do now ?Again, barring health issues, yes. I've had cataracts, so my world sort of faded to foggy white. My colours were not off, but I needed 3cm high font to read anything. All fixed now. My mother lost most of here colour vision and was amazed when it was restored. All the vivid hues and such that she'd forgotten about.
*What's your favourite colour ? (US translation service: "colour" = "color" sheesh !!)Boring if there's only one. The prior owners of my house liked gold. All the drapes, carpets, hardware, and even the cars. Sheesh indeed...
Why do we prefer certain colours over another ?I don't, so don't know.
Where do norty light rays go ?Ah yes, but they’ll have time to reflect on what they did wrong
guffaw chortle !!
unless i've missed them, i have never seen a warning on a pack of liquorice. not good.The liquorice labelling act (2019) has been delayed by Brexit taking all parliamentary discussion time for the past n years. Perhaps when the log jam has cleared ......
Does this then mean that the Sun is a moon of Sagittarius A ?Few stars actually orbit Sgr-A. The sun is not one of them as its orbital speed is far too large at this distance from such a small object. No, we go around the galaxy in a non-elliptical path and if we orbit anything, it is the general cloud of assorted objects and (mostly) dark matter that exists mostly (but not entirely) within the radius of our circuit. Sgr-A is only a tiny percentage of this mass, and is thus just one of those assorted objects.
