Noticed no one had posted the simple chords, so here it is for those who like that sorta
I enjoy playing Gravity kinda chill from time to time and this is the aid. Transpone or 
to your desire, this is the original key of A. I myself prefer this song in C.

For the intro you can do instrumental verse humming that riff, or you can start on a G 
go into the verse.

AThere's (x02220@1)a fracture in the color bar
In the backseat of a parked car
GBy (320003@1)the liquor store where the streetlight
AKeep (x02220@1)you company 'til the next night

AIn (x02220@1)the same town, there's the same scar
In the same glow of the liquor store
GBy (320003@1)the freeway, where the headlight
AKeep (x02220@1)her company 'til the next night

A (x02220@1)      DOh! (xx0232@1)Gravity.
          A (x02220@1)        DWhy (xx0232@1)can't we seem to keep it together?
A (x02220@1)           DSons (xx0232@1)of my enemies,
          A (x02220@1)          DWhy (xx0232@1)can't we seem to keep it together?

(this is the piano part, I typically just A D A G to lead back into the verses when on 
guitar, or you can create some nasty dissonance, whatev you want, be creative.)

AIn (x02220@1)the back room of the Pentagon
There's a thin man with a line drawn
GWith (320003@1)a red jaw and a red bite
AWatch (x02220@1)the headline on the next night

A (x02220@1)      DOh! (xx0232@1)Gravity.
          A (x02220@1)        DWhy (xx0232@1)can't we seem to keep it together?
A (x02220@1)           DSons (xx0232@1)of my enemies,
                      DWhy (xx0232@1)can't we seem to keep it together?
F#m (244222@1)         DWhy (xx0232@1)this tragedy?
          A (x02220@1)         DWhy (xx0232@1)can't we seem to keep it together?
A (x02220@1)      DOh! (xx0232@1)Gravity.
          A (x02220@1)        GWhy (320003@1)can't we seem to pull it together?

A (x02220@1)             A (x02220@1)In the fallout, the fallout
A (x02220@1)               D (xx0232@1)                 A (x02220@1)We found out the hype won't get you through
A (x02220@1)              A (x02220@1)We're connected, connected
A (x02220@1)              D (xx0232@1)                 A (x02220@1)      D (xx0232@1)
