“…We find that the Tsallis parameter takes negative values for range 0.5 < n < 1.2 with r < 0.0132, where negative values of the β have different physical meanings. The tendency of total entropy to decrease may mean the creation of dark energy or extra dimensions [24] in the tissue of spacetime. This points to a quintessence type of dark energy in the constant-roll inflation field.…”

“…In addition to the string-chaotic inflation models n = 2 3 and n = 4 5 , all potential values in the range of 0.5 < n < 1.2 under the small values of tensor-to-scalar ratio can be included in string-chaotic potential models and so in string landscape. It is known that quintessence dark energy [69] naturally emerges from string theory landscape solutions [62] and this may be a realistic approach to defining the structure of spacetime tissue [24]. Furthermore, dark energy solutions in the theory produce negative solutions of instead of positive ones, which correspond to anti-de Sitter vacua [69,70].…”

“…If so, the universe should be in the proper phase state (i.e., quintessence phase) after the de Sitter vacuum. In particular, it may lead to both opening up extra dimensions [24] in the tissue of spacetime and the creation of normal matter. Therefore, when compared with the Bekenstein entropy relationship S = A 4G with A = 4π R 2 A , the Tsallis entropic proposal, which proposes a modification, reveals two phases.…”

“…The sum of the entropy of the apparent horizon and the matter (the generalized form of entropy) should show an increasing trend with cosmic time or must be greater than zero when taking the Clausius relation into account. From a thermodynamic point of view, for example, zero entropy denotes a perfect structure [24] without the disorder. Particularly in the early inflation of the universe [25,26] entropy can be less than zero, and this may be related to the creation of dark energy or extra dimensions [24].…”

In this work, we investigate the high-energy era of the universe from the constant-roll condition perspective by taking the Friedmann equation, which is modified by a non-additive Tsallis entropic proposal. In the framework of the observational data, we determine the constant-roll parameter. Under the fixed field condition of the constant-roll parameter, for the wide range of the power-term of the chaotic potentials, $$\sim \phi ^{n}$$ ∼ ϕ n , which involves some string-chaotic potential models, $$n=\frac{2}{3}$$ n = 2 3 , $$n=\frac{4}{5}$$ n = 4 5 , the non-additive (nonextensive) Tsallis parameter is analyzed graphically. The resulting analysis shows that, in addition to a quasi-de Sitter phase, any value of the range $$0.5<n<1.2$$ 0.5 < n < 1.2 points to a dynamical form of the dark energy (quintessence) in the early universe. It implies that n values in the range may be included in string-chaotic potential models. The non-additive Tsallis parameter provides this with the help of its negative values in the constant-roll field.

Trapped graviton in magnetic seas induces magnetic fields as a function of time in the additional space. The Soon Joe generator made the Graviton set behave as free relativistic quantum particles. The current and voltage generated when the LED was turned on and off were measured five times. Measurements were made in units of 1/1000 of a second, and the measured data were summed. In the LED off‐state, the average current was −2.87E‐03 (A), and the average voltage was −1.44E‐01 (V) in VH and 6.83E‐01 (V) in VL. The average current in the LED on‐stage was −4.28E‐03, the VH was 2.14E‐01, and the VL was 6.57E‐01. The voltage difference was −8.27E‐01 in the off‐stage and −8.71E‐01 in the on‐stage. Less current was generated in the off‐stage, with less voltage difference. In this experiment, we confirmed that the graviton generates the current, and with the photons, more current is generated. This explains why the interactive induction protocol of gravitons or photons can be used to experiment with the magnetic field's ability to communicate or transfer energy with relativistic quantum particles. The gravitoelectric effect explains the photoelectric effect elements, and graviton has induced electricity as a physical entity in the magnetic sea.
