I do not recall there ever being radiation damage of any sort being associated with black triangle craft or boomerangs.

FastFourierTransform,
Terribly sorry, but I recall that you had asked me to get folks to fill out your poll over on the SFIA forum. Here is a link to the responses:

Apologies for forgetting!

Please see the Self Contained Ion Powered Aircraft now also just called an Ion Propelled Vehicle. It has an onboard power supply and is powered solely by ions. It does not need a nuclear power supply, extra wings, or helium. Here are about 2 dozen videos of it:

This is an interesting video that demonstrates the sounds attributed to ionocraft and black triangles in general.

We've got some new modelling done on the Phoenix Lights craft by our very own RetroVisor !

To really get an idea of the scale of this thing and how it would've appeared in the sky, checkout his Sketchfab presentation HERE .

INTRODUCTION:
For some of you reading this, you probably think that UFOlogy is pseudoscience and intellectual tripe. For others, you may be a little more open-minded and remain skeptically intrigued by the idea. We’re also sure that some of you are so-called “believers” in the phenomenon.

Exactly. It is in fact thought that the Tabby's Star fluctuations are caused by a disintegrating planet. There was a fairly statistically-insignificant chance of us actually viewing that as it happened, but it just goes to show how busy the universe is.

(Just a thought. :lol:)
Aye, it's a fun thought. Other danger stars could be experiencing the same treatment near us!

32657 I have already considered whether the decrease in the brightness of Betelgeuse could not have been caused by a kind of star-lifting.
That sounds pretty ridiculous. Even if you manage to focus the stellar mass quite a bit, it will still be a pretty thin soup to harvest. Betelgeuse is ...

I predict that we will all either be 6 ft under by then or we will all reside in immortal artificial bodies by then!

Chances are good that if we'd survive up until then, those stars would have been diffused by us by some means along the lines of star-lifting.
