"I wonder about a couple of things. One, having the past and present neutrons side by side, rather than looking at the past neutron. If one is to "see" both of them, wouldn't one have to "have" two of them?"

I would think so, Bowser. <shrug> Maybe, they should try using 'radio' waves first:

Interesting movie. In that movie, the Hamm radio was the 'connector' and present in both the past and present.

This is the second theory I've seen where they have used the sun for time travel. The first, is by actually traveling towards the sun and going around it a few times at the right time and speed so that when you come out of it's orbit/the other side, you'll be in the future. I suppose that going around the sun counter-clock-wise would take you to the past. :}
