Lyric discussion by massofclouds 

Basically, this song is saying that "he" screwed up. He doesn't know how to explain it, because it was against reason, whatever he did. He wants to be able to explain what he did with science and reasoning, but he just can't, because love doesn't work like that. And this person means everything to him, so he wants to try it over again, but the other person thinks that there should be something to explain it.

My favorite song I've heard by Coldplay. I can't wait 'til the new album comes out tomorrow.

Oh yeah, this description seems about right. You can watch the video on youtube and what Massofclouds is saying fits it perfectly.

i agree as well, I wish he would have mentioned that in the end there really isn't anything to explain. You just simply move on. I feel the love song could have take into more depth.

That is exacly what I thought, he wants to go back with her he did Screwed up. He wants to make up for it. He wants to explain to the chick what he has done, but for some reason he doesn't know how to explain to her.
