Replying to the questions put to you doesn't seem to be your forte, does it Line_112? I put four to you and you respond to just one. A success rate of just 25%. Why would you predicate your argument on such an average? Could you please explain your reasoning and how you arrive at the...

Why would you predicate your argument on such an average? Could you please explain your reasoning and how you arrive at the conclusion of there being (on average) no more than one radio-emitting civilization in the Milky Way. Could you then explain your reasoning for applying that average to...

Ok, this isn't about radio telescopes per se, but it's about the 'why bother about space if it doesn't affect us' attitude. In 2013 the Russian city of Chelyabinsk got lucky when an incoming meteor caused a 400/500 kiloton airburst overhead. Nobody was killed. There were some injuries and a...

Provided that we keep on building bigger and better radio telescopes, it's a win - win scenario, Line_112. If they detect no other intelligent life then that will tell us that it is either very rare or absent. Knowing that we can better understand our place in the universe. Or, if a signal...

One might well ask, does it make any sense to build new optical telescopes like the EELT? Or new space-based telescopes like the JWST? Or new gravitational detectors like LIGO, KAGRA and Virgo? Or new neutrino telescopes like Hyper-Kamiokande and IceCube? Or new particle accelerators like...

I see. The map you posted does give preference to the extragalactic origin of GRBs because there is no clustering of them on the plane of the galaxy, which would have been the case if they were intragalactic. But you clearly cannot bring yourself to admit or accept that. My three questions...

Then, if you found nothing to support your claim and if you rely on others to clarify the issue, your claim (that absorption is sufficient) remains unsupported by you personally. I therefore find myself unpersuaded by your argument and the lack of evidence to support it. Your say so and your...

There are two problems with your reply, Line_112. The first is that you still haven't cited any values for gamma ray absorption by the interstellar medium. Until you do so or link to a reputable source which does, we have no way of testing and checking the validity of your claim that GRB's are...

Have you heard of Occam's Razor, Line_112? https://en.wikipedia.org/wiki/Occam%27s_razor I would suggest that your argument is disfavoured by the use of the Razor. Thank you, Cerenkov.

Line_112, I have two things to say to you, which I will do across two separate posts. Below is a contour map of weak gravitational lensing, taken from the Wiki page on that subject. https://en.wikipedia.org/wiki/Weak_gravitational_lensing If I claimed that there was a spherical structure...

Then I don't understand the point of you attaching your map in support of your claim. It shows us nothing of what you claim is there because what you claim we are seeing is an illusion. As Ibix has also pointed out, you have cited no values about absorption by the interstellar medium...

Then if your source says nothing that can answer my questions Line_112, could you please answer them? Here they are again. A. How could such a spherical subsystem have originated? B. How it could have persisted? C. Why we seem to find ourselves at it's centre? Thank you, Cerenkov.

I see no concentration of GRB sources along the plane of the galaxy in your map, Line_112. Could you please show me where this concentration is?

Does the Astronet source say anything about... A. How such a spherical subsystem could have originated? B. How it could have persisted? C. Why we seem to find ourselves at it's centre? Thank you, Cerenkov.

Ok then. But since you've taken an interest in this thread Ibix, could I please ask you to check the logic of what I'm about to say? It's about Line-112's map of the distribution of gamma ray sources and what that distribution implies about the position of the Earth relative to the centre of...
