Would you like to borrow my asbestos suit?wolram said:
I know that Wolram - I was just making light of the reaction you would get if you seriously promoted Setterfield here.wolram said:
I'm sorry, Marcus. I don't know if I can behave well enough to survive while Wolram borrows my suit.marcus said:
You may have to get one of your own... Hey! you're still alive! You've already got one, you devil. Apparently, Barry has not yet heard about the 2df survey results.wolram said:
Red shift refers to the phenomenon where light from distant objects in space appears to be shifted towards the red end of the spectrum. This can be explained by the Doppler effect, where objects moving away from us will have their light waves stretched, causing them to appear more red. Red shift is important in astronomy because it provides evidence for the expansion of the universe and allows us to measure the distance and speed of objects in space.
Halton Arp was an American astrophysicist known for his controversial theory that challenges the traditional interpretation of red shift. His theory, known as the "intrinsic red shift" hypothesis, suggests that red shift is not solely caused by the expansion of the universe, but also by other factors such as the ejection of matter from active galactic nuclei.
Arp's theory is primarily based on his observations of unusual red shift values in certain pairs of galaxies, where a smaller, lower red shift galaxy is seen connected to a larger, higher red shift galaxy. He also points to examples of quasars, which have extremely high red shifts, but are located in close proximity to galaxies with much lower red shifts.
Arp's theory has been met with skepticism and criticism from many in the scientific community. The majority of evidence and observations support the traditional interpretation of red shift as a result of the expansion of the universe. However, some scientists continue to explore and study Arp's ideas, as the debate over the true nature of red shift remains ongoing.
If Arp's theory were to be proven correct, it would challenge our current understanding of the universe and the mechanisms behind red shift. It could potentially lead to new discoveries and insights about the nature of galaxies and the expansion of the universe. However, until more evidence is gathered and verified, the traditional interpretation of red shift remains the dominant perspective in astronomy.
