Greene has grown on me. I find Tyson sometimes brilliant like when he said to Stephen Colbert that some day space will have expanded so much that future generations will not be able to see other galaxies and deduce theirs is the only one and their science will be based on that. But what "keeps him up at night" is the possibility such a thing has already happened. But on a moment to moment basis I find him repellent. Cox is basically informative ASMR. Greene seems more like Feynman in being relateable to us dumber people.<br><br>That being said looking for an energy loss as a clue to other dimensions is probably folly. What you need is a detector surrounding a chamber that is as empty as possible. And even if this chamber doesn't capture energy from another dimension you would have a good experiment for virtual particles, quantum tunneling, vacuum energy,  etc.
