"Neutron Star Collision (Love Is Forever)" is a song by the English rock band Muse, featured on the soundtrack to the 2010 film The Twilight Saga: Eclipse.

Matt Bellamy explained that the song was written after he split with his longtime girlfriend at the end of 2009, and was based on his feelings at the beginning of their relationship.

While Muse featured on the Twilight and New Moon soundtracks previously (with "Supermassive Black Hole" and a special remix of "I Belong to You" respectively), this marks the first time the band has produced the lead single for a movie.

In a positive review, BBC Music described the song as Muse "turning their reality-altering Preposteriser Ray on their own back catalogue".

Above and Beyond Magazine wrote: "Neutron Star Collision... reminds [me] of their previous work Origin of Symmetry, which is in my mind, the real and honest Muse.
