Boltzmann brains is a theoretical prediction of random

fluctuations to understand the universe as a whole.

A century ago Boltzmann considered a “cosmology”

where the observed universe should be regarded

as a rare ﬂuctuation out of some equilibrium state

(the entropy of a closed system always increases)

----

The Universe (as whole) is a flat, smooth, homogenous

isotropic and cold.

After every cosmic event horizon there is another similar

cosmic event horizon and so and so . . . to infinity.

There is a fundamental fact in the Nature that the ordinary

matter in the Universe (as whole) is very few, and its critical

density is about 9.9 x 10^-30 g/sm^3. That masses of density

cannot ''close'' the Universe into a sphere and therefore the

Universe as a whole is an infinitely flat continuum.

#

Space is ''pretty flat'' to within 0,5%, according to the

WMAP 2013 measurement.

-----

In this infinite, zero cold (T=0K) equilibrium ''closed''

continuum the quantum fluctuations take place as

Quantum physics says to us today

and Boltzmann said to us a long time ago.

''Boltzmann Brain'' saves the universe from heat death.

----

What is the conclusion?

1 - Quantum physics is about quantum energy (E=h*f)

2 - Boltzmann thermodynamics is about heat (E=kTlogW)

3 - The unity between Quantum energy and Boltzmann

micro-thermodynamics saves the universe from heat death.

This unity is the basis for Quantum gravity.

This unity is the basis for Star formation.
