A couple of questions from someone struggling to put this in more relatable terms: Isn't information in theoretical physics just mean something that repeats, or perhaps relatable, in some way - for example an underlying structure similar to other structures - and in that sense is measurable information another form of describing mass/energy, like moving between frequency and time domain in signals? (side note: could the significance of information be a by product of using math to describe physics, as math can only describe properties of repeating systems, so high information is equilivant to being easily captured in mathematical terms) And on his experiment, assuming his theory is correct - why would a hard drive represent "pure data", such that writing to it would constitute adding an exact measure of information to mass? For example, in an erased state the drive would have ambient information from surrounding electrical fields, is there some mechanism to erase the drive that ensures it lacks any information? And why would data that a computer can read not be inefficient in some way and contain information irrelevant to the hard drives usage, causing it to measure higher even if this exact mass of information is correct? The weights seem so small that even the smallest bit of environmental interference would make this experiment fail.
