Would a magnetic 1 weigh more or less than a magnetic 0? I have no idea but it is a question worth asking.
If a 1 is an electrical or magnetic charge and a zero is an absence of a charge, is it possible that they weigh differently (given my analogy above of compressed air weighing more than non-compressed air).
Any physics gurus that know whether electricity or magnetism has weight? We know that light has weight...

Not a guru, exactly, but let me
weigh in on the matter, anyway. :sly
Electrons have mass. So the electrons moving through a wire (electricity) have mass. However, throw the switch to turn off the flow, and the electrons don't go away. They just stop moving along the wire. So the question really is whether the mass changes when current is flowing. The only way that could happen is if relativity kicked in. An object gains mass as it gains speed. But even there, it's not that simple. The electrons in a wire are always moving, whether in electric current or not. When current is flowing, there is a net motion in one direction. When it is not, they move randomly, so no net movement in any direction. Bottom line, I'd have to say no, electricity has no weight (mass), at least not in a way that makes a 1 weigh differently from a 0.
But: not sure if all the above applies in semiconductors, like transistors on chips. When their state changes, I think there is a change in the number of electrons present at the junctions. Where those electrons go, I dunno. They must be carried away to somewhere else in the circuit, I suppose. So no net change in the mass of the computer, due to changing a 1 to a 0 or vice versa, I would think.
Magnetic charge? Nah. No mass there. And no mass change for when the polarity changes. It's just the orientation of atoms that are there, with or without a magnetic charge.
Now, paper tape and punch cards. That's where we have a difference in weight between a one and a zero! Ah. Those were the days. You could actually
see the bits.
