The cosmological constant problem concerns the extremely small value of the cosmological constant compared to the Standard Model mass scales. Recent studies suggest a scalar field with a flat potential may explain this. The Dark Energy Spectroscopic Instrument (DESI) reported results indicating dark energy may vary over time, deviating from the ΛCDM model. This paper shows that a simple linear potential scalar field can explain the DESI anomaly. The model proposed by the author predicts time-varying dark energy consistent with DESI data. The scalar field's potential, defined at a low energy scale, represents dark energy. The paper discusses how the scalar field's potential can explain the DESI anomaly and the cosmological constant problem. The scalar field's potential is derived from inflationary scenarios, where the cosmological constant relaxes. The scalar field's potential is shown to predict a time-varying dark energy consistent with DESI data. The paper also discusses the implications of this model for future research and the need for a UV completion. The scalar field's potential is shown to be consistent with the DESI data and the cosmological constant problem. The paper concludes that the scalar field's potential provides insights into the cosmological constant problem and the DESI anomaly.The cosmological constant problem concerns the extremely small value of the cosmological constant compared to the Standard Model mass scales.
