In summary, the paper discussed a method proposed to challenge the LCDM model by utilizing the BigBOSS project at UC Berkeley. The success of this project could potentially put the LCDM model in a precarious position if dark energy is found to be questionable. Additionally, BigBOSS is an expansion of the BOSS project, which aims to create a three-dimensional map of a large portion of space using data from over 1.5 million galaxies and tens of thousands of quasars. BigBOSS intends to surpass BOSS in scope by including data from 24 million galaxies and 2 million quasars across the entire Northern Hemisphere.

This paper, http://arxiv.org/abs/1401.7438, proposes a method to falsify the LCDM model based on the BigBOSS project currently under development at UC Berkely. The LCDM model would be under serious stress if dark energy proves suspect. In a nutshell, from http://www.moore.org/newsroom/press-releases/2012/12/04/a-big-boost-to-bigboss, "BigBOSS takes its name from BOSS, the Baryon Oscillation Spectroscopic Survey now underway as the largest component of the third Sloan Digital Sky Survey, which is creating a three-dimensional map of a large volume of space using 1.5 million galaxies and tens of thousands of quasars; BOSS has already produced powerful new cosmological results. BigBOSS is designed to be bigger than BOSS in every way, reaching deeper into space and building its map from 24,000,000 galaxies and 2,000,000 quasars across the entire sky of the Northern Hemisphere."

I definitely enjoyed reading that article, be interesting to see how it works out.

BTW first time I heard of the concordance model as bein referred to as the "Vanilla model" lol
 

1. What is LCDM and what does it stand for?

LCDM stands for Lambda Cold Dark Matter, which is a cosmological model used to explain the formation and evolution of the universe.

2. What is the role of "Lambda" in the LCDM model?

Lambda, also known as the cosmological constant, is a parameter in the LCDM model that represents the energy density of dark energy, which is responsible for the accelerated expansion of the universe.

3. What is "cold dark matter" and why is it important in the LCDM model?

Cold dark matter is a type of matter that does not interact with electromagnetic radiation and is thought to make up about 85% of the total matter in the universe. It is important in the LCDM model because it helps explain the large-scale structure of the universe and the movement of galaxies.

4. How does the LCDM model explain the formation of the cosmic microwave background?

The LCDM model predicts that in the early universe, there were small fluctuations in the density of matter. As the universe expanded and cooled, these fluctuations grew and eventually led to the formation of structures, including galaxies and galaxy clusters. The cosmic microwave background is a remnant of the radiation from this early universe and provides evidence for the LCDM model.

5. What is the role of the BigBOSS project in studying LCDM?

The BigBOSS project is a large-scale astronomical survey designed to map the distribution and movement of galaxies in the universe. This data will be used to test and refine the predictions of the LCDM model and provide a better understanding of the structure and evolution of the universe.
