The bubble-universe and a physico-chemical analogy of the cosmological   constant
  An analogy is developed between the bubble universe model and the Young-Laplace equation obtaining an analogic equation and commenting some numerical results produced by its application. The results, even if based on a simple analogy, appear quite intriguing and very close to the experimentally estimated or calculated values. Some conceptual and numerical limitations of such an analogic approach are also indicated.
