AI Thread Summary
Flaws in the IMAP data due to solar system polarization may impact our understanding of cosmic background radiation, suggesting a need for revised views on the early universe. The discussion highlights that while this could affect interpretations of the WMAP data, it is unlikely to significantly alter dark matter calculations, which rely on various methods like galaxy rotation curves and N-body simulations. The caution raised emphasizes the importance of not over-relying on specific interpretations of WMAP data, as they are theory-dependent. Overall, the implications of the flawed data may prompt a reevaluation of certain cosmological models but are not expected to render dark matter irrelevant. The conversation underscores the complexity of interpreting astronomical data accurately.

:confused: I Read an article about the IMAP data being flawed because of polorizations in our solar system, if this is true does it have implications on the amount of matter we have calculated, and if it does would dark matter be irrelevant, kind of a naive question but the article was a little vague can someone clarify the errors and make a guess at the implications :confused:

I think that you're are speaking about this information appearing in November:
http://bulletin.cern.ch/eng/articles.php?bullno=48/2004&base=art

"The theorists' new mathematical analysis picks out the large-scale fluctuations from the tumult of the background radiation in maps from the Wilkinson Microwave Anisotropy Probe (WMAP). Their reanalysis suggests, surprisingly, that the observed microwave radiation has a foreground superimposed on it from the motion and orientation of our solar system. If so, the researchers say, cosmologists may need to revise their views of the early universe. Using WMAP to estimate the date the first stars formed, for example, depends heavily on the cosmic bass."

Though I don't see how it can have implications in the calculations of dark matter, since dark matter is calculated from diverses sources: the rotation curves of galaxies, N-body experiments,...

It's a warning though, not to put too much confidence on a specific interpretation of the WMAP data.

The data may be detailed and precise, but the interpretation put upon it is theory dependent.

Just a thought.

I hope you all had a very Happy Christmas and will have a thoughtful and Happy New Year!

Publication: Redox-driven mineral and organic associations in Jezero Crater, Mars Article: NASA Says Mars Rover Discovered Potential Biosignature Last Year Press conference The ~100 authors don't find a good way this could have formed without life, but also can't rule it out. Now that they have shared their findings with the larger community someone else might find an explanation - or maybe it was actually made by life.
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.
