I know this is a tangent from a tangent, but why is it that Obi-wan and Yoda dissipated as they died? I know the official explanation is that they are now in the ‘netherworld of the Force’ and can only appear as ghosts to those they knew, but that netherworld doesn’t require their physical bodies to allow them to project ghost bodies, otherwise Anakin wouldn’t have been able to do it in ROTJ.

Conspiracy theory: Neither Obi-wan nor Yoda is actually dead, instead they teleported via the Force to another location in the galaxy and only appear occasionally in ghost form to other people. It makes some sense, since Luke assumes that Yoda is too strong in the Force to actually die, and Yoda seems to imply that it is possible. If it is the Force that prolongs life, Obi-wan could still technically be alive - it even looks like he aged a bit in ghost form, a highly suspicious activity for a ghost.
