 03:05: ... energy density but also by pressure. Both mass energy density and any positive pressure act to decelerate the universe to cause it to recollapse. In fact for ...


20190109: Are Dark Matter And Dark Energy The Same?
 08:10: That gives a positive pressure, and in general relativity positive pressure adds an attractive gravitational force, no matter what causes it.
 12:59: ... negatives in what is probably not a negative mass, antigravitational, positive pressure, antideSitter space ...


20160518: Antigravity and the True Nature of Dark Energy
 04:36: ... is this how dark energy is causing expansion to accelerate, by causing positive pressure? ...
 05:39: ... slowly, even if the overall energy density of those regions is the same Positive pressure pulls the universe ...
 07:58: But we just discussed how positive pressure can't cause expansion to accelerate outwards.
 08:28: Well, positive pressure pushes outwards, like in our pressurized tank.
 08:47: But positive pressure pushes out.
 09:19: Relativistically, negative pressure has to do the opposite of positive pressure and results in antigravity, because math.
 10:12: A volume has negative pressure if it takes work to expand, just like a volume with positive pressure takes work to compress.
 10:44: It's the opposite effect to positive pressure.
