As we discussed earlier (in one of your posts or mine, I don't remember), I am now trying to make shorter posts, easier to read with much less details (questions on the details can always come in the comments, where I am glad to give more information). I am happy if you liked this post and if it was clear (enough). :)
I like how you presented this new method of "resurrecting" nuclear compounds through dark matter, as a means to detect it (?).
You can remove the question mark from your sentence. This is the exact idea.
To rephrase and summarise the post a little: One should take all these pieces of nuclear waste, put them together so that we will have a large amount of matter living in an excited state and staying excited (because those pieces of waste have a very long lifetime). If a stealthy dark matter particle comes around, the excited waste gets a mean to de-excite (thank you dark matter!) by transferring its energy to dark matter. As a result, dark matter is now more energetic and the experiments targeting it have can detect it more easily.
Enjoy your day as well!
