Özet:

 

I point out a simple but usually overlooked fact about the  cosmological constant problem: to solve the cosmological   constant problem it is sufficient to find a symmetry or   mechanism that sets the cosmological constant to   zero or to a tiny value at some time in the past,   provided that general relativity is the relevant theory   of gravity,   and the energy-momentum tensor (excluding   the part of the form of a cosmological constant) is   conserved.   The relevant symmetry or mechanism need not be applicable   today. Any additional cosmological constant term   induced by a phase transition in the energy-momentum   tensor in this case is compensated by a shift in   the cosmological constant term of gravitational origin.
