Now we know how much mass a minus-sign has ... 10^-41kg ;)

 1bit of information stored at 300K has a mass of 10^-38kg according to [0]. That’s a few orders of magnitude off but almost uncannily close.
 A fully-populated 128-bit storage pool would contain 2^128 blocks = 2^137 bytes = 2^140 bits; therefore the minimum mass required to hold the bits would be (2^140 bits) / (10^31 bits/kg) = 136 billion kg.136 billion kg:- ≈ 0.64 × mass of trash produced in the United States in one year ( ≈ 2.36×10^8 sh tn )- ≈ 0.35 × estimated wet biomass of all humans alive ( ≈ 385 Mt )- ≈ 1.3 × estimated dry biomass of all humans alive ( 105 Mt )thanks wolframalpha!
 Another one: 136 billion kg is the mass of a block of water with a footprint of a square kilometer and a height of 136 meters. Put this way, it does not sound that much anymore, in my opinion.
 However, it needs to be 'pure energy' not mass, a body of matter.

 arbitrage 5 months ago [–] moores law hasn't been accurate in decades, and it was widely regarded as a boondoggle of a throwaway statement for the press well before that, too.
 Hold up. The article shows a mass difference of 10^-38 for the matter/antimatter states. That’s not a few orders of magnitude off your number, that’s literally your exponent.
 The article gives the mass difference in grams, not kilograms. That’s where the factor of 10^-3 to the number in my top comment comes from.
 Ahhhh. Tricky units!
