How much does a terrabyte weigh

[Philip Hardcastle]

According to those that believe in the CoE as being absolute they were concerned about black holes and information. They were concerned about a potential violation of the laws of physics if information was lost in a black hole.

They settled the argument between themselves by saying information must be conserved and that accordingly there was no violation.

The above is a very short precis.

My point is if information is part of CoE then a Terrabyte equals energy and thus it must also equal mass if stored on a chip or disk, do you agree and if so how much would it weigh, and if so could we accurately weigh things to see how much information they contain?

Got to be honest, I weigh a few pounds too much so I am hoping I am full of information. LOL

A terabyte weighs exactly....ZERO.

Memory is essentially just switches on or off.  No mass difference when memory is full or empty, but it takes energy to make memory change state.

A bit can exist in the form of a photon. Having a photon can mean ON and having no photon can mean OFF. Also, the lower bound of a photon's energy is only limited by the lower limit of photon's frequency. Also, photons have no rest mass, and when converted into mass, their energy and mass are both very very small, especially at very long wavelengths.

In other words, there is no foreseeable lower limit on a terrabyte's energy content.

You should consult "Claude Shannon".

He looks like a skinny chap on his photo.

As you, I have more "information" than him lol.

A terabyte weighs exactly....ZERO.

Some mass MUST be employed to store some information.

I agree that the state weighs zero but to store that state then it must be contained in a substrate with mass.

If my computer memory is 1GB and I have half filled it then you are right, I have not increased its mass from zero filled. But remember even when the memory is empty it is still full of zeros, it is still 1GB of information, just all zero.

If compression were employed then the required mass would depend on the informational complexity.
