10 ^18 Amps, Universal Record for Current

Click For Summary

Discussion Overview

The discussion centers around the measurement of an exceptionally high electric current of 10^18 amps associated with a cosmic jet from the galaxy 3C303, as reported by researchers. The scope includes theoretical implications of such a current, its measurement techniques, and its potential significance in astrophysics.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants highlight the significance of the measurement of 10^18 amps as a record for electric current in cosmic jets, referencing the work of Phil Kronberg and colleagues.
  • One participant humorously suggests the potential for harnessing this current to solve energy problems on Earth, indicating a speculative application of the findings.
  • Another participant questions the appropriateness of the forum for such a topic, suggesting it may be better suited for a different context.
  • A later reply affirms that the topic is suitable for discussion in the current forum, emphasizing the remarkable nature of the amperage measurement.

Areas of Agreement / Disagreement

Participants generally agree on the remarkable nature of the current measurement, but there is a light-hearted debate regarding the relevance of the topic to the forum's focus. No consensus is reached on the appropriateness of the forum for this discussion.

Contextual Notes

The discussion does not resolve the implications of the cosmic current measurement or its potential applications, leaving open questions about its significance and relevance to terrestrial energy issues.

A COSMIC jet 2 billion light years away is carrying the highest electric current ever seen: 10^18 amps, equivalent to a trillion bolts of lightning.

Philipp Kronberg of the University of Toronto in Canada and colleagues measured the alignment of radio waves around a galaxy called 3C303, which has a giant jet of matter shooting from its core. They saw a sudden change in the waves' alignment coinciding with the jet. "This is an unambiguous signature of a current," says Kronberg.

We present radio emission, polarization, and Faraday rotation maps of the radio jet of the galaxy 3C303. From this data we derive the magnetoplasma and electrodynamic parameters of this $50$ kpc long jet. For one component of this jet we obtain for the first time a direct determination of a {\it galactic}-scale electric current ($\sim 10^{18}$ A), and its direction $-$ {\it positive} away from the AGN. Our analysis strongly supports a model where the jet energy flow is mainly {\it electromagnetic}.

Quick! Let's hook up a huge motor to it and solve the world's energy problems for the next billion or so years.
 
Hi Dave, thanks for your post.

Should it be taken from your friendly humor and the obvious fact that stuff happening out in space usually lacks much significance to us here on earth, that I have posted inappropriately in the Electrical Engineering forum? Perhaps this sort of thing would have been better posted elsewhere?

Respectfully yours,
Steve
 
No, here is fine. This was just my way of saying, "HOLY !&#*!" I never pay attention to which forum something is in - it's more about the substance (and that is one whopper of an amperage!)
