Information converted to energy

I have always argued the Universe is made of Information.

Information -> Energy -> Matter

We know energy compressed becomes matter  with E=MC^2
Well E=IC  where C is some constant also.  Information converted to energy
Among the many responses to this conundrum was that of Leó Szilárd in 1929, who argued that the demon must consume energy in the act of measuring the particle speeds and that this consumption will lead to a net increase in the system's entropy. In fact, Szilárd formulated an equivalence between energy and information, calculating that kTln2 (or about 0.69 kT) is both the minimum amount of work needed to store one bit of binary information and the maximum that is liberated when this bit is erased, where k is Boltzmann's constant and T is the temperature of the storage medium.

this was fantastic

i have often wondered - what is the maximum information density of free space ?

how much information can be stroed in a cubic meter of space ?
