Thanks for the nice comment.

That's a fascinating new theory. Thanks for breaking it down so that even I could follow - I didn't feel the need to call the committee for the prevention of torture. ;-)

I was also shocked when I typed CPT in google to find a few references.... (but this is not the stupidity in this post). And then I laughed... ;)

You say the right-handed neutrino would be almost impossible to detect - is this because of its weak interactions with other particles?

It is in fact completely decoupled and we can only track its gravitational effects to see it. Which is why no dark matter experiment will ever be able to see it...
