Discussion Overview

The discussion revolves around the detection of a mysterious cosmic noise, with participants exploring its implications, potential explanations, and the reliability of current cosmological models. The scope includes theoretical considerations, observational challenges, and the need for further investigation in astrophysics and cosmology.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants express skepticism about the noise being a genuine astronomical phenomenon, suggesting it could be a scientific mistake due to the early stage of investigation.
  • Others highlight the unexpected nature of the noise, noting it is significantly louder than predicted, which raises questions about existing cosmological models.
  • A participant mentions the need for more observational devices beyond ARCADE to confirm the findings, indicating a gap in current observational capabilities.
  • There is a contention regarding the reliability of the Lambda-CDM model, with some arguing it is well-supported by evidence, while others challenge its validity based on recent anomalies.
  • Some participants emphasize the complexities of astrophysics and cosmology, suggesting that misunderstandings are common as the field develops.
  • A later reply questions the relevance of cited articles, asking for clarification to facilitate a more productive discussion.
  • One participant inquires about potential follow-up projects to ARCADE, expressing a need for further radio observations to explore the cosmic noise more thoroughly.

Areas of Agreement / Disagreement

Participants exhibit a mix of agreement and disagreement. While some support the reliability of the Lambda-CDM model, others express doubts and highlight the need for further investigation into the anomalies. The discussion remains unresolved with competing views on the implications of the cosmic noise and the state of cosmological theories.

Contextual Notes

Participants note that the current understanding of cosmology is still developing, and many assumptions may not yet be fully tested. There are also references to the limitations of existing observational data and the challenges in interpreting new findings.

Who May Find This Useful

This discussion may be of interest to those engaged in astrophysics, cosmology, and observational astronomy, as well as individuals curious about the implications of new cosmic discoveries.

Thanks RunSwimSurf, this is interesting stuff for me cause I've always wondered what is really out there. I really think this should be looked at more carefully, the most common thing i think it could be is a scientific mistake which are actually pretty common and considering this is only like the 2nd day, there is still way to much we don't know about this.
It would be interesting if there were more devices that could confirm this noise because all i know about is ARCADE at the moment and never heard of this guy.. and the noises are louder and farther then ever?? weird.
If the sound stops and restarts then seems to be coming from our moon then i think this could be my last blog posting :( they are coming!
 
"The universe really threw us a curve," Kogut said. "Instead of the faint signal we hoped to find, here was this booming noise six times louder than anyone had predicted."

"We really don't know what it is,"said team member Michael Seiffert of NASA's Jet Propulsion Laboratory in Pasadena, Calif.




This is a common theme in cosmology today.

It stems from us using untested assumptions as the basis for buidling our cosmological models.

A correct theory can be measured by its predictive powers.

"I am feeling both humble and perplexed by this," said Anderson, who is now working as a retiree. "There is something very strange going on with spacecraft motions. We have no convincing explanation for either the Pioneer anomaly or the flyby anomaly."

The mystery is that the “blue blobs” are found along a wispy bridge of gas strung among three colliding galaxies, M81, M82, and NGC 3077, residing approximately 12 million light-years from Earth. This is not the place astronomers expect to find star clusters: in the "abyssal plain" of intergalactic space. “We could not believe it, the stars were in the middle of nowhere”, says de Mello.

"We knew there were really massive young galaxies eons ago, but we thought they had all matured into older ones more like our Milky Way. If these galaxies are indeed newly formed, then this implies parts of the universe are still hotbeds of galaxy birth," said Dr. Chris Martin.

"It was quite a surprise to us," admits Kuulkers. However, after running a series of checks, the team satisfied themselves that the oscillations were indeed taking place 1122 times a second (1122 Hz). - In reference to a supposed "neutron" star spinning 1122 times a second.

"We were very surprised to see the flare", says Waite. "The rapid increase in intensity over such a large area was quite unexpected and is hard to explain".

"At first I didn't believe it," says THEMIS project scientist David Sibeck of the Goddard Space Flight Center. "This finding fundamentally alters our understanding of the solar wind-magnetosphere interaction."

Nope. It's because cosmology is a very new science (before about 15 years ago, there was very, very little cosmological data). Any new science always goes through growing pains while the scientists figure out how to not make errors. You can expect that the vast majority of the anomalies found are misunderstandings of astrophysics (astrophysics, the physics of objects out there in the universe, is vastly more complex than cosmology, and therefore vastly easier to get wrong).

The basics of cosmology, however, are unlikely to be overturned by simple astrophysics due to the preponderance of the evidence. It's possible, of course. Just not likely.

Which is why the success of the Lambda-CDM model puts it on such firm footing. I suppose if you only read popular news articles, you're not going to get a balanced view of the science. They tend to sensationalize the small number of weird findings, while discounting the much more typical null observations that line up perfectly with Lambda-CDM.
 
Excuses bore me.

Don't be an appologist, be a scientist.

Ignorant trolls bore me.
 
Ignorance is saying the lcdm model is on "firm footing".
 
I agree with Chalnoth - it looks like a troll. Your cites do not appear to connect with whatever point you are trying to make. Please clarify so we can have a lucid conversation. I'm all for that.
 
I'm pointing out the "suprises" that are a constant reminder of our current theory's failure.

If that's considered trolling these days, I fear for the state of science.

So, what is the followup project to ARCADE? We've got space observatories for all of the other wavelengths - except radio. We need something chilled down to 2.7K, and I don't think any of the space/VLBI plans have liquid helium.

I would expect another balloon experiment to look at another 7% (or more) of the sky, but I couldn't find anything. Anyone know?

Cheers,
--Jake
