regarding the former shift we talked about; is there any survey done on it?
Yes, the CfA Redshift Survey, the DEEP2 Redshift Survey, the Sloan Digital Sky Survey
Redshift
The first redshift survey was the CfA Redshift Survey, started in 1977 with the initial data collection completed in 1982.
how does the redshift show galaxies are moving away from us If a source of the light is moving away from an observer, then redshift occurs; if the source moves towards the observer, then blueshift occurs. what is meant by this red term? In physics, redshift is a phenomenon where electromagnetic radiation (such as light) from an object undergoes an increase in wavelength. the kind of radiation you mentioned here; what is it actually? In physics, electromagnetic radiation refers to the waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. which equation is related to it? Maxwell's equations who is this person? James Clerk Maxwell was a Scottish scientist in the field of mathematical physics what is stated in this equation? According to Maxwell's equations, a spatially varying electric field is always associated with a magnetic field that changes over time.

Redshift [SEP] Redshift surveys
With advent of automated telescopes and improvements in spectroscopes, a number of collaborations have been made to map the universe in redshift space. By combining redshift with angular position data, a redshift survey maps the 3D distribution of matter within a field of the sky. These observations are used to measure properties of the large-scale structure of the universe. The Great Wall, a vast supercluster of galaxies over 500 million light-years wide, provides a dramatic example of a large-scale structure that redshift surveys can detect. The first redshift survey was the CfA Redshift Survey, started in 1977 with the initial data collection completed in 1982.
