I thought this was self explanatory, but maybe I missed a nuance here and there.
Edit: Apologies to all, I am not sure who I am replying to here, I think the quote I took is from one of channel1's posts, and here I have replied to someone else. I blame it on the caffeine, and the phone call that interrupeted my post. Oops.
If I understand Hawking correctly, the reason you can only see one universe is that a given universe is bounded by space-time, whose limiting dimension (constant?) is the speed of light. Thus, if you can see it, it is by default within your space-time universe, so you could never 'see' a second universe. You could 'be in a second universe' but then you'd only see that one. While that makes sense to me, I might have tripped on the physics somewhere.
This brings me to the head scratching problem of 'how do you deal with and study something that you can't see?' Do you use some quantum version of the electron microscope, one that can peek through wormholes?
And now to the problem for the engineers out there: How do you grind the lens for that device? If you thought tolerances were tough in the manufacture of slip rings or ball bearings, how about the tolerances for the manufacture of quantum tools? :lol:
