Comment on the paper «The cosmological constant (Λ) as a possible primordial link to Einstein’s theory of gravity, the properties of hadronic matter and the problem of creation»

  • A. Beesham


DerSarkissian (1985) has recently presented some new cosmological models based on Einstein’s field equations with variableG and Λ, claiming that energy conservation cannot occur. We show that this claim is incorrect and we rediscuss the question of energy conservation in the corresponding field equations.

DerSarkissian (1985) ha presentato recentemente alcuni nuovi modelli cosmologici basati sulle equazioni di campo di Einstein conG e Λ variabili, sostenendo che la conservazione di energia non si può verificare. Si mostra che questa affermazione non è corretta e si ridiscute il problema della conservazione dell’energia nelle corrispondenti equazioni di campo.
