Chris Klimek of The Washington Post called the song "haunting" and stated that "Gravity is strong evidence that Bareilles's songcraft may yet warrant the stardom she's attained.
"[5] The Hollywood Reporter mentioned the song in their review of one her concerts, stating it was the "night's bravest and most powerful performance" when "she brilliantly sang fan favorite Gravity".
[7] In an homage to the short film Powers of Ten, the music video for "Gravity" features a single unbroken take of Bareilles strolling in the middle of a street while people are walking behind her bringing lights, balloons, and globes of other planets representing a journey through the solar system and into deep space.
[10] Kelly Clarkson covered the song in Durham, North Carolina, during her Stronger World Tour, in which she praised Bareilles's voice and lyrics.
A shipping video featuring a clip montage of the characters Annie and Jeff set to "Gravity" was made by a Community fan in November 2009, halfway through the first season of the show.
[14] The video inspired show creator Dan Harmon[15] and he included a similar sequence of clips of the two characters in the second season episode "Paradigms of Human Memory".
Bareilles eventually made an appearance as a hot-air balloon guide in "Intro to Felt Surrogacy", the ninth episode of the series' fourth season.
