I had never considered it like that, but it feels true. Do you have some reference material for the statement that gravity and quantum effects are “negative ene

  It's not difficult to derive why the gravitational potential energy must be negative.[0] For the cosmological implications of this fact, there's Lawrence Krauss's book "A Universe from Nothing", also "The Inflationary Universe" by Alan Guth, and Stephen Hawking touches on it in "A Brief History of Time."
