Life. Multiverses. Humans.
The Multiverse theory, introduced in the 1980s, can explain the "luckily small" amount of dark energy in our Universe that enabled it to host life, among many universes that could not. Using huge computer simulations of the cosmos, research has found that adding dark energy, up to a few hundred times the amount observed in…

Counting till the end… Numbers… Infinite… Water and fire…
Gisin, of the University of Geneva, debates the physical reality of real numbers. His main problem lies with real numbers that consist of a never-ending string of digits with no discernable pattern and that can’t be calculated by a computer. Such numbers (like π for example) contain an infinite amount of information: You could imagine…

Boltzmann's idea of entropy and the Creator: An unexpected end…
While reading a scientific paper for thermodynamics (Ted Jacobson, Entropy from Carnot to Bekenstein, arXiv:1810.07839 [physics.hist-ph]) I came up to a reference of Boltzmann’s (and later on Planck’s) notion that entropy corresponds to the logarithm of the number of microstates compatible with a macrostate, and that entropy is maximized in equilibrium. Given that, one can…
