SUMMARY

The discussion centers on the validity of dark matter and dark energy hypotheses in light of potential inaccuracies in observational data, particularly from the IMAP satellite. Participants highlight concerns regarding local phenomena affecting measurements, specifically the polarization effects in our solar system. While the WMAP team has accounted for these factors, debates persist about the influence of certain experimental contaminants on the power spectrum, particularly the octopole moment term. Overall, the conversation emphasizes the need for a critical reassessment of existing theories in cosmology.

PREREQUISITES
  • Understanding of dark matter and dark energy concepts
  • Familiarity with cosmological measurements and the role of satellites like WMAP and IMAP
  • Knowledge of power spectrum analysis in cosmology
  • Awareness of polarization effects in astronomical data
NEXT STEPS
  • Research the implications of polarization effects on IMAP data accuracy
  • Study the octopole moment term in the cosmic microwave background power spectrum
  • Explore alternative theories to dark matter and dark energy
  • Investigate the methodologies used by the WMAP team in their measurements
USEFUL FOR

Astronomers, cosmologists, and physics students interested in the foundational theories of the universe and the ongoing debates surrounding dark matter and dark energy.

I know why the dark matter and dark light hypothesis exist to explain the universes apparent mass; when our calculations say it is only a small percnetage of the universes actual mass etc, and the Hubble constants apparent increase and so on, but what if what we are looking at is innacurate? The reason I ask is that polarizations in our solar system have skewed the IMAP data so that it's inaccurate, meaning our theory needs to be altered to allow for this; could it be that our assumptions are wrong and there simply is only visible matter in the universe? What other ideas are there to explain the incosistencies and are we any closer to finding an answer?

Any answers greatfuly received.

Thanks

The people who worked on WMAP and the like are very careful to account for local phenomena in their measurements.. Be sure that such things are contained in the error bars of the measurement. There is some debate about a certain octopole moment term in the power specturm, that might be contaminated experimentally, but that's not going to change the bulk measurement of some of those startling universal constants (by more than say .1% or so) .
 
I see thanks for that Haelfix, that's the trouble with some articles they tend too exaggerate.
