Although I am unable to judge this paper it should make an interesting read to toughs that can.

Here we investigate the limits imposed by thermodynamics to a DE fluid. We proof that thermodynamics rule out DE fluids.
Therefore, we believe that we have demonstrated precisely that the vacuum energy remains the strongest candidate to explain the current accelerated expansion of the Universe and the cosmological constant problem remains as one of the biggest problems of the theoretical cosmology.
Dark energy is a hypothetical form of energy that is thought to make up around 70% of the total energy in the universe. It is believed to be responsible for the accelerating expansion of the universe, and its exact nature and properties are still being studied by scientists.
The existence of dark energy was first proposed in the late 1990s when scientists observed that the expansion of the universe was accelerating, rather than slowing down as expected. This was confirmed by multiple independent studies, including measurements of the cosmic microwave background radiation and the large-scale structure of the universe.
Dark energy fluids are theoretical fluids that are used to describe the properties and behavior of dark energy. They are often modeled as a type of energy that is distributed throughout the universe, rather than being concentrated in specific locations like matter and radiation.
Scientists are studying dark energy fluids through a variety of methods, including observations of the universe, theoretical calculations, and experiments using advanced technology such as particle accelerators. They are also constantly refining and developing new models to better understand the nature of dark energy.
Recent research has suggested that dark energy may be even more mysterious and complex than previously thought. Some studies have proposed new theories and models, while others have attempted to better understand the properties and behavior of dark energy through observations and experiments. However, the exact nature of dark energy and its role in the universe is still a subject of ongoing research and debate.
