What does it mean about the song defying gravity?

Answer:
The song basically is about Elphaba breaking free and where people believe she is "Wicked". She believes things are corrupt in OZ and everything is a lie, she is showing people she isn't accepting limits, and that no one can stop her or bring her down. This is where Elphaba cannot turn back, and unfortunately Glinda won't follow her path.
