Rob Sheldon notes that the more real-world information we have, the less the bits weigh until, at very large amounts of information, they weigh almost nothing.
Holloway: If [Melvin] Vopson is correct we now have a mystery because his theory is in tension with the conservation of energy. The only solution is that the system is not closed. So where is the opening in the system? If the system is physically closed, then the influx of information must come from outside the physical realm.
Sheldon: Throughout history we have examples of these bad physics generalizations. For example, heat was once considered a fluid embedded in the oak log, absorbed from the sun, called phlogiston. As it turned out, heat is not a material substance.
