Reply to James Webb Telescope captures the same galaxy at three different points in time in a single mind-boggling image by mirzavadoodulbaig
Astronomy is so many minds-blown ahead of me by now that I'll never catch up. RIP me.

That makes a lot more sense! Fucking lensing.. Got me again!

No, it is one image. The objects are behind another supermassive object which causes gravitational lensing, and you see it three times. Because of the extra distance it has to travel as the light bends, you are seeing the objects in different moments in time.
Edit: I forgot to mention there is also something called time dilation with gravity, and the more you have it the slower time travels, so the images that are lensed with the most gravity arrive later in time.

How many galaxies that we see are redundancies?

I assume ( because I'm not the sharpest tool) that would be the case only if it too was affected by the lensing.

As one idiot to another, your logic is sound.

Although, I could just be an idiot who doesn’t understand what’s really going on. Make sure to take that into account if you are considering responding to my comment..

NASA had to remind SpaceX that the risk of a collision isn't zero. So.....

These folks are highly educated engineers and professionals. The only person taking it lightly is you, and your hyperbole.
I’m not buying it.
Go rant somewhere else please.
Have a great day, but kindly move on with this fear mongering.
This conversation is foolish.

I'm just saying that to blithely disregard the risks involved with these things is kind of foolish.

Yeah. LEO orbit is huge. We’ll be good. Cheer up.

I guess the point is that, regardless of whether you give a shit or not about collateral damage, the world likely will give a shit.
Mega-constellation debris cascades are a serious concern and shouldn't be dismissed. To do so would be extremely naive and/or foolish.

I’m not going to convince the Chinese of anything.
They literally don’t care. They don’t even make sure their Long March boosters won’t deorbit and hit land in a populated area.
Since they show they don’t care, why would your argument about the Chinese be something I take even remotely seriously?
Hey China!
I DONT GIVE AN EFF ABOUT YOUR STATION. LEARN TO CONTROL YOUR BOOSTERS BEFORE WE TAKE YOU SERIOUSLY.

Also, let’s talk about human rights when you have a moment.
