Interpreting SDSS extragalactic data in the era of JWST

In summary, the CERN talk discussed the use of empirical evidence from the SDSS to challenge the ΛCDM standard model of Big Bang cosmology. The presenter proposed a new predictive "temporal geometry" model consistent with de Sitter's exact solution, which addresses discrepancies such as the Hubble constant tension and lensing anomaly. Further validation of this model is needed from the mathematical physics and cosmology communities.

Talk Description (Abstract)
We present empirical evidence from the Sloan Digital Sky Survey (SDSS), including statistically-significant, independent measurements of galaxy theta-z, redshift-magnitude, and redshift-population. These corroborating data sets are clearly inconsistent with the optimal ΛCDM standard model of Big Bang cosmology, exacerbating the Hubble constant tension; the σ8 (clustering parameter) discrepancy; the lensing anomaly; the large-angular-scale anomalies in CMB temperature and polarization; and other anomalies that now confront cosmologists. A set of predictive equations are put forward that are consistent with de Sitter's exact solution to the Einstein field equations; this new predictive "temporal geometry" model, which requires vetting by the mathematical physics and cosmology communities, is consistent with the SDSS data and relieves the unexpected new tensions in cosmology created by initial and ongoing JWST observations.

The CERN talk and presentation materials provide a fascinating look into the current state of interpreting extragalactic data in the era of the upcoming James Webb Space Telescope (JWST). The speaker presents empirical evidence from the Sloan Digital Sky Survey (SDSS) that challenges the current standard model of Big Bang cosmology and raises important questions about the Hubble constant, clustering parameter, lensing anomaly, and other anomalies that have been observed.

The speaker also introduces a new predictive "temporal geometry" model that is consistent with the SDSS data and offers a potential solution to these tensions in cosmology. However, they also acknowledge that this model requires further vetting by the mathematical physics and cosmology communities.

Overall, this talk highlights the exciting and ever-evolving nature of cosmology and the important role that data interpretation plays in shaping our understanding of the universe. With the upcoming launch of the JWST, we can expect even more groundbreaking discoveries and challenges to our current models of the universe, and it will be fascinating to see how this new data will impact our understanding of the cosmos.
 

1. What is SDSS and how does it relate to extragalactic data?

SDSS stands for Sloan Digital Sky Survey, which is a project that has been mapping the universe since 2000. It has collected data on millions of galaxies, including their positions, colors, and spectra. This data is used to study the large-scale structure of the universe and to understand the properties and evolution of galaxies. The extragalactic data from SDSS is particularly useful for studying galaxies outside of our own Milky Way galaxy.

2. What is the significance of interpreting SDSS extragalactic data in the era of JWST?

The James Webb Space Telescope (JWST) is the successor to the Hubble Space Telescope and is set to launch in 2021. It will have a larger mirror and more advanced instruments, making it capable of observing the universe in greater detail and at longer wavelengths. This will greatly enhance our ability to study extragalactic objects, and interpreting SDSS data in conjunction with JWST observations will provide a more comprehensive understanding of the universe.

3. How does SDSS extragalactic data complement observations from other telescopes?

SDSS data is unique in that it provides a large-scale view of the universe, while other telescopes may focus on specific objects or regions. By combining data from multiple telescopes, scientists can create a more complete picture of the universe and gain a deeper understanding of the properties and evolution of galaxies.

4. What challenges are faced when interpreting SDSS extragalactic data?

One challenge is the sheer volume of data that SDSS has collected over the years. It can be overwhelming to sort through and analyze such a large dataset. Additionally, the data may contain errors or biases that need to be accounted for in the interpretation process. Another challenge is understanding the limitations of the data and how it may affect the conclusions drawn from it.

5. How can interpreting SDSS extragalactic data in the era of JWST contribute to our understanding of the universe?

By combining the large-scale view of the universe provided by SDSS with the high-resolution observations of JWST, scientists can gain a more detailed understanding of the properties and evolution of galaxies. This can lead to insights into the formation of structures in the universe, the distribution of dark matter, and the role of supermassive black holes in galaxy evolution. Ultimately, interpreting SDSS extragalactic data in the era of JWST can help us better understand the origins and fate of our universe.
