Hot shots weren't the only things she posted, however ... because a string of text on Jodie's IG story Thursday seemed to point directly to her recent divorce filing.
She reposted a quote about quantum physics, which talks about "a particle vibrating due to your sound when you speak," saying it can affect a molecule inside a star "at the edge of the Universe instantly."
It says the phenomenon is known as "quantum entanglement" ... and added, "The greatest illusion of this Universe is the illusion of separation."
The timing here is telling ... TMZ broke the story, Jodie pulled the plug on her marriage with the "Dawson's Creek" star earlier this week, citing the usual "irreconcilable differences" in the divorce docs.
BTW, while Jodie was sharing photos of herself having a blast overseas, Joshua was spotted loading his car at a Whole Foods in Los Angeles. While he has yet to speak out, it appears they're living very different lives amid their split.
