The cosmological constant problem is reanalyzed by imposing the limitation of the number of degrees of freedom (d.o.f.) due to entropy bounds directly in the calculation of the energy density of a field theory. It is shown that if a quantum field theory has to be consistent with gravity and holography, i.e. with an upper limit of storing information in a given area, the ultraviolet momentum cut-off is not the Planck mass, Mp, as naively expected, but where Nu is the number of d.o.f. of the universe. The energy density evaluation turns out completely consistent with Bousso’s bound on the cosmological constant value. The scale , that in the “fat graviton” theory corresponds to the graviton size, originates by a self-similar rearrangement of the elementary d.o.f. at different scales that can be seen as an infrared-ultraviolet connection.
The scope of this paper is to examine the
complications raised by technical innovations in the financial field (fintech).
The conclusion of this enquire is that the current institutional architecture
cannot guarantee monetary and financial sustainability as long as Governments
decide to reform it using the already available instruments (cryptocurrency,
blockchain, algorithms) instead of leaving them free to operate or limiting
their use as they are doing. The same goes for any tentative to restate bank
credibility forecasting money and financial instability starting from big data
treated with traditional econometric methods.
