Comments by "Mark Pawelek" (@mark4asp) on "Physicist Despairs over Vacuum Energy" video.

  1. “Vacuum energy is positive and has a constant density throughout space. Thus, increasing the volume of space increases the total amount of vacuum energy, which requires work. It is the opposite of a gas, whose energy and density decrease as it expands. When that happens, the gas exerts positive pressure. In contrast, because vacuum energy is positive, it exerts negative pressure, so galaxies on the largest scales are pushed apart, not pulled together.” <- Nonsense on so many different levels it's comical. The author uses a negative comparison with gas as a metaphoric example! Can't do that, 1) gases are actual matter, Vacuum energy is not. Real gases exert pressure. Fictional vacuum energy pulls things apart.
