Here is the arxiv link: https://arxiv.org/abs/1901.08588

There seems some overlap with this other recent paper: https://arxiv.org/abs/1905.05216

Haven't looked at either in any substantial way.

1. What is the cosmological constant?

The cosmological constant is a term in Einstein's field equations of general relativity that is used to describe the energy density of empty space. It is often represented by the Greek letter lambda (Λ) and is thought to play a role in the expansion of the universe.

2. What is the significance of a new paper on the cosmological constant?

A new paper on the cosmological constant can potentially provide new insights and understanding into this fundamental aspect of the universe. It may also offer new evidence or theories that could challenge or confirm existing models of the universe.

3. What is the methodology used in the new paper on the cosmological constant?

The methodology used in the new paper on the cosmological constant will depend on the specific study or research being conducted. It could involve theoretical calculations, observational data analysis, or experimental simulations.

4. How does the new paper on the cosmological constant contribute to the field of cosmology?

The new paper on the cosmological constant may contribute to the field of cosmology by providing new insights, theories, or evidence that can help further our understanding of the universe. It may also open up new avenues for research and exploration in this area.

5. Are there any potential implications or applications of the findings in the new paper on the cosmological constant?

The findings in the new paper on the cosmological constant could potentially have implications for our understanding of the universe and its evolution. It may also have applications in other fields, such as astrophysics and particle physics, where the cosmological constant plays a role in their theories and models.
