Einstein again +, on large scale.

In summary, the conversation discussed a paper that confirmed the general theory of relativity on large scales through weak lensing and galaxy velocities. The paper used shape measurements of over 30 million galaxies and the lensing signal around LRGs to achieve a high signal-to-noise ratio. The conversation also mentioned the upcoming BOSS survey and how it will further support gravity theories. It was noted that the paper also supported dark matter and dark energy theories.

Interesting paper -- thanks for posting this!

Using shape measurements 20 of more than 30 million source galaxies
covering the same area as the LRG sample, we calculate the lensing signal
around the LRGs and stack them together to achieve a high signal-to-noise ratio

Now that is impressive

and they are waiting the the Baryon Oscillation Spectroscopic Survey (BOSS) to smash any gravity theory contender.

Thanks, a very much interesting confirmation. Thanks for sharing. :rofl:
It also supports dark matter and dark energy theories.
 

1. What is the theory of relativity?

The theory of relativity is a fundamental scientific theory developed by Albert Einstein in the early 20th century. It explains the relationship between space and time and how they are affected by gravity. There are two main theories of relativity: the special theory of relativity and the general theory of relativity.

2. How did Einstein contribute to our understanding of the universe?

Einstein's theory of relativity revolutionized our understanding of the universe. It provided a new framework for understanding gravity and how it affects the motion of objects in space. It also led to the development of new technologies, such as GPS, and helped to confirm the existence of black holes.

3. What is the significance of "Einstein again +, on large scale."?

This phrase refers to Einstein's continued contributions to scientific understanding, particularly in regards to the large-scale structure of the universe. Einstein's theories of relativity have been instrumental in shaping our current understanding of the cosmos.

4. How does Einstein's work on large scale relate to his previous theories?

Einstein's theories of relativity, particularly the general theory, are essential for understanding the large-scale structure of the universe. They provide the mathematical framework for describing the behavior of massive objects, such as planets, stars, and galaxies, on a cosmic scale.

5. What impact has Einstein's work had on modern physics?

Einstein's work has had a profound impact on modern physics. His theories of relativity have been crucial in developing our understanding of gravity, time, and space. They have also paved the way for new theories and discoveries, such as quantum mechanics, that have further advanced our understanding of the universe.

Suggested for: Einstein again +, on large scale.
