And if the two actually do interact, it could mean that both have a common origin. And they're referring this as the dark dimension. So string theory suggests that there could be six or more dimensions in addition to our own three spatial dimensions. In one of time, the dark dimension might be considerably larger than a microscopic one of the string theory. Graviton, these are the theoretical particles that give rise to gravity, might be able to leak into the enlarged dark dimension. So if so, they would attain more mass and become dark gravitons. These then would reside inside the dark dimension, but their effects would be seen in other dimensions as well, letting them play the role of ascribed to dark matter. And this would lead to a natural coupling between dark energy and dark matter. So a lot of theory right now.
