Did anyone read about Boltzmann brains in 18 August (no. 2617) edition of NewScientist?
Quote from page 29, 'What little brains are made of':
"As empty space contains a repulsive force known as vacuum energy, it can eventually spawn particles, atoms and even, in theory, conscious entities. These hypothetical "Boltzmann brains" - spontaneous observers of the space around them - challenge our place in the universe. .......
...... In theory, they could take on almost any form, but the larger and more complex they are, the less likely it is that they will appear, according to the laws of probability and quantum mechanics. They could be disembodied brains with eyeballs, floating in outer space. They could consist of a whole body, encased in a space suit and equipped with an oxygen tank. ......."
Could someone better versed in physics that I explain how this hypothesis does not violate the first law of thermodynamics?
