FRB's source as Rail and/or Coil Guns (or mass drivers)

In summary, the conversation discusses the possibility of Fast Radio Bursts (FRBs) being caused by rail and/or coil guns, or mass drivers. However, this theory is unlikely due to the technical limitations and speculative assumptions involved. The conversation also references an experiment that observed radio emissions from a firing rail gun, but it is not enough evidence to support the FRB theory. Overall, the discussion concludes that the source of FRBs is still unknown.

Summary: FRB's source as Rail and/or Coil Guns (or mass drivers)

Hello,

I've been studying rail and coil guns recently, and certain applications of this technology can result in some pretty high speeds with a significant amount of mass. I've been wondering if these FRB's could be a result of these? By my calculations, that amount of force could result in a extremely high %c velocities. In fact, if you could harness 10^30 to 10^33 Joules of energy, then one would see a huge lorentz factor...

The main problem with this tech, would be slowing. But I wonder if you have a mass driver, would it be possible to design something at the point of arrival, with a similar mechanism, as a mass "catcher."

Additionally, someone did an experiment where they observed radio emissions from a firing rail gun. Link: https://apps.dtic.mil/dtic/tr/fulltext/u2/a470631.pdf

To me, the spectra seem to fit with an FRB, but I'm not a physicist by trade, just curious. Also, if the object has a small diameter, but it's VERY long, then one would see a strange dispersion measure from one of these events, assuming emission along a rail as the mass travels along the thing.

Curious to see what folks would think of this?

Thanks,

Mike

No. You implicite some extraterrestrial lifeform using railguns, and produce radio signals, which we detect.
It is extremely unlikely that such lifeforms exist with the exact level of technology. If they do, why should the use railguns? If they exist and use railguns, why should theirs emit radio signals? Hence

If they exist,
if they have a similar level of technology than us,
if they use railguns,
if their railguns emit radio waves,
if this all happens within the range which we can observe,

then the signals will still be far too weak for us to detect considering the distances we observe FRBs from.

And the duration and frequency of occurrences are the next problems.

So even if we assume five big IF, we still ran into the problem that our observations do not match such a potential cause.Since the entire subject is based on too many speculative assumptions, compared with the technical impossibility, this thread is closed.
