Is the cosmological constant constant?
v. 3 n. 14
The cosmological constant, symbolized by capital Greek letter lambda, Λ, is the more formal term for the unknown dark energy that is conventionally believed to be causing the observed accelerated expansion of the Universe. It is an adjunct to general relativity that makes the theory conform to this observation on the large scale. Note, though, this is a phenomenological attachment to a mathematical theory and a somewhat discordant relationship. *
As well as curvature lambda has been associated with the energy density of space, energy/volume, and conventionally assumed constant. But where is all this energy flooding into the Universe coming from? According to the First Law of Thermodynamics, energy cannot be created (or destroyed), but only converted from one form to another. ** The energy is kinetic in nature, and apparently causing the Universe to accelerate at about 10^-14 m/s^2. *** Regardless of origin, at the onset of lambda this energy had to be potential. But still, where did this potential energy come from, which should be infinite in quantity if in the present kinetic form it is constant?
A way out could be apparent if the actual Universe extends beyond the observable of some 93 billion light years diameter. Then any change in lambda might become apparent, and this enigma might be resolved, as discussed.??If lambda does not ultimately diminish, creation of infinite energy from an unknown source must be explained. The choice seems to be between the Law of Conservation of Energy (the First Law of Thermodynamics) or the conventional conception of the cosmological constant.
What if Einstein was right in his rejection of the cosmological constant ("the worst blunder of my life"), and general relativity in its pure logical form ultimately does not require it to describe the Universe as fully expressed? What if the Universe extends beyond the observable limit and lambda diminishes to zero or becomes negative sufficiently to cancel completely, so that the Law of Conservation of Energy for the Universe as fully expressed is maintained (with a net energy of zero)? ?

7 个月It could just be coming from negentropy and the continual new form within which the shapes refine ever more complex yet ever greater folds. That’s maybe the energy we seek. Energy after all is just life information. Urgent response receptivity of a virtual field of particles, emerging in solitons in recursive emergence and return, across all dimensions in spatial reality. It’s pretty obvious to me.
