actually, saying that photons are split in two isn't far off the truth - in a really hot star the a photon has enough energy to make an electron and a positron. The photon hits a nucleus and is absorbed, and then the electron and positron are emitted immediately afterwards.

So a photon goes in and an electron-positron pair comes out, so you could say the photon has been split into two parts.
