Do the gaps in protoplanetary disks really indicate newly forming planets?

Roughly 5 billion years ago Earth was in the process of forming. Gas and dust gathered with the young sun's protoplanetary disk, likely nudged a bit by the resonant gravitational pull of Jupiter and other large worlds. One ...
