This video presents papers that suggest that dark energy, which is what we call the energy responsible for the expansion of space, may be created from black holes, which collapse space.
Black holes neatly fit the idea that 3 dimensional spacetime should collapse inwards towards e dimensions. Black holes are often said to have a 2 dimensional event horizon. If 3 dimensional reality collapses to a 2 dimensional manifestation, it makes sense that the 2 dimensional manifestation would then collapse upwards to 3 dimensional manifestations; is dark energy the manifestation of the upwards collapse of 2 dimensional space?
