Mystery of strange radio bursts from space

Click For Summary

Discussion Overview

The discussion revolves around the nature and potential origins of Fast Radio Bursts (FRBs), particularly focusing on the observed discrete steps in their Dispersion Measures (DM). Participants explore various hypotheses regarding whether these signals are of terrestrial or extraterrestrial origin, and the implications of their findings on the understanding of FRBs.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants note a potential discrete spacing in DM of FRBs, suggesting integer multiples of 187.5 cm-3 pc, which could indicate a non-extragalactic origin.
  • There is a proposal that if the observed DMs are valid, they may point towards a galactic source or even an artificial source, as high DMs would typically be influenced by intergalactic dust.
  • One participant raises the possibility of a correlation between the observed DMs and terrestrial time standards, suggesting a human association with the signals.
  • Another participant questions the natural explanations for the observed patterns, emphasizing the difficulty in finding such explanations given the specific multiples of 187.5 cm-3.
  • A participant expresses curiosity about a potential pattern involving π in relation to the DM steps, leading to a discussion about the validity of such a connection.
  • Concerns are raised about the accuracy of calculations linking the DM to the Hydrogen line, with one participant correcting another's misunderstanding of the units involved.

Areas of Agreement / Disagreement

Participants express a mix of skepticism and intrigue regarding the origins of FRBs, with no clear consensus on whether they are of terrestrial or extraterrestrial origin. Multiple competing views remain, particularly concerning the implications of the observed DMs and the potential for human-made signals.

Contextual Notes

Some participants highlight limitations in the current understanding of FRBs, including unresolved mathematical steps and the dependence on specific definitions of terms like Dispersion Measure. The discussion also reflects a variety of interpretations regarding the implications of the observed data.

@bahamagreen
With such a minute data set at there is at present, it is indeed possible to discover other hypothetical relations.
You can probably hypothesize dozens of them, any of which might be discountable with just one more observation.
You are definitely leaping in the dark with the assumption that extraterrestrials are interested in us and are trying to tell us something.

I'm joking about the ETs...
rootone: "...any of which might be discountable with just one more observation." Exactly.
Hypothesis testing and prediction of subsequent data... we should not be passively waiting to find out what detection 12's multiple will be; we should be predicting it because the existing data seems improbably not random.

Even the microwave oven interpretation should be offering a prediction for the most likely multiple of detection 12...

Ah OK, I thought the ET speculation was a bit odd coming from you. :biggrin:

And that seems like a good place to close the thread.
