This is the cleverest way of integrating science into romance that I have seen in a long time. I love the idea that they experience the same photons. I wish I could come up with stories as clever as this.

Beautifully written.

Romantic physics, novel and well written. The Multiverse is such an interesting concept, one I use a lot in my own writing ideas.
Many Blessings.

Beautiful and bittersweet. They will both move on with their lives, as promised to each other. Nonetheless, I have always felt that Will would be the less likely between the both of them to be able to more successfully move on. Still, they would be happy for each others sake before they come together again. Thank you for sharing this wonderful snippet.

... ALL. MY. FEELS. Be right back. Tissues are required.

This was beautiful. I loved the blending of science and Will's musings about Lyra - they fit together perfectly, and your writing is so fluid, and so moving.
