Much ado about nothing? Local void & LCDM

[Chronos]

This paper - The Local Void: for or against ΛCDM?,http://arxiv.org/abs/1401.6459 - puts to the test the question of low galaxy counts in the vicinity of the Milky Way. It has been suggested this poses a problem for LCDM. Using the Millennium II supercomputer at the Max Planck Supercomputer Center, a ten billion particle dark matter numerical analysis was performed and revealed such voids are not only possible, but, probable under reasonable LCDM assumptions.

Interesting. I wonder how long it took them to calculate that, lol.

The millennium II run required 1.4 million cpu hours over 2048 cores. In other words, the supercomputer required about a month to crunch all the numbers.

Very cool. More or less what I expected. The ΛCDM model has proven to be remarkably resilient, and I really think it's a bad idea to bet against it.

As a scientist, it is important to critically examine and test theories and assumptions in order to gain a better understanding of our universe. The paper, "The Local Void: for or against ΛCDM?" addresses a valid concern about the low galaxy counts in the vicinity of the Milky Way and its potential implications for the ΛCDM model.

The use of the Millennium II supercomputer at the Max Planck Supercomputer Center to perform a ten billion particle dark matter numerical analysis is a powerful tool in investigating this issue. The results of this analysis suggest that under reasonable ΛCDM assumptions, such voids are not only possible but also probable.

This is an important finding as it adds to the growing body of evidence that supports the ΛCDM model. However, it is also important to note that this study is just one piece of the puzzle and further research and analysis is needed to fully understand the implications of local voids on the ΛCDM model.

In conclusion, while the paper may seem to suggest that the concern about low galaxy counts in the vicinity of the Milky Way is much ado about nothing, it actually provides valuable insights and adds to our understanding of the universe. It is only through continued scientific inquiry and rigorous testing that we can gain a deeper understanding of the complexities of our universe.
