Too much information

I'm not entirely sure why this is important to physics, but still, here's the abstract of a study trying to estimate all of the information capacity of the visible universe:

The information capacity of the universe has been a topic of great debate since the 1970s and continues to stimulate multiple branches of physics research. Here, we used Shannon’s information theory to estimate the amount of encoded information in all the visible matter in the universe. We achieved this by deriving a detailed formula estimating the total number of particles in the observable universe, known as the Eddington number, and by estimating the amount of information stored by each particle about itself. We determined that each particle in the observable universe contains 1.509 bits of information and there are ∼6 × 10⁸⁰ bits of information stored in all the matter particles of the observable universe.

But but - this doesn't include the information possible by how you arrange the elementary particles, does it?  It's all a bit confusing...
