Meh.  false color is such a tease.

Alonjar: Meh.  false color is such a tease.


Why?

I don't know, I saw a pretty cool one earlier.

Yes, but were there a hundred of them?

Showing them all to scale is interesting in itself, but some of the coolest ones get lost in the margins.

common sense is an oxymoron: Alonjar: Meh.  false color is such a tease.

Why?


Because it's not real. That picture is based on reality, but it's a gross abstraction. It is equally as real as a cartoon, maybe even less so. Like magnetic lines being represented visually or five pointed starts in a cartoony black sky.

Because it will rub you through your jeans but when you unbutton them it suddenly says it has to go home because it has a big meeting in the morning.

To be fair, everything humans have invented, including logic, mathematics and physics, are gross abstractions. They are not reality, they are human-derived descriptions of reality.

But a camera is real. It's the base physical. Gamma and Xray are real. A camera that shows gamma and xray in the visible spectrum is real.

It's as real as the image formed by your eyes; the gases in the nebulae are real, the photons they emit and/or reflect are real, and the relative brightnesses of different parts of the nebulae are real. The only difference is that the colors have been chosen to highlight the distribution of certain chemical elements (also real) instead of matching the human eye's color response.

How many of them can you identify?

I see the Coalsack Nebula, along with the Mote in God's Eye.

Oh wait, that's only visible from New Caledonia ;)

We can't see gamma and xrays, so we need instruments to translate them into a format agreeable to our limited range of vision. It's like speaking to a Korean through an interpreter: It helps you understand him, but you still don't know Korean.

You are mistaking the tools we use to understand reality as being reality itself. Once again: You are not experiencing reality. You are experiencing a human perception of reality. And that is an important, if perhaps irrelevant, distinction.

Ishkur: You are not experiencing reality.


Actually, you ARE experiencing reality. Reality is the little world you build up in your head, your senses' limitations, and all that jazz is reality to you.

You're confusing reality with the base physical, which is merely, as the name suggests, the base or foundation of reality. It's one part. The base physical part that matters here when all we have is a few errant high energy photons from before australopithecus met Arthur and the Tick. We don't have any way or need to accurately express the mental aspects of something that that hasn't existed for millions of years. All we have is a black an white image created by detectors. That's more than enough. Giving it a peacock hue is just silly, because we all know blackbody radiation means everything heats to the same colors. B&W astronomy FTW! You want color photos? BUILD A PROBE AND GO THERE.

That's not reality. That's your version of it.

What you are doing is confusing reality for our knowledge of reality -- as in, how can we really know anything to any degree of absolute certainty.

Yes, it is possible that we may be completely wrong about everything. We do not possess the ability to jump outside our skulls - outside human perception, reasoning, and comprehension of the natural world and its faculties - and truly observe the Universe on a completely impartial level. Everything we know comes to us through biased human filters. Even things we think are universal absolutes, like logic, math and physics - they're all human constructs: Human tools created by humans and used by humans to understand human perceptions of the Universe in human terms that humans can understand, for the benefit of humanity.

We may be way off with all of this and never know it. The true answers may never be knowable, but that's okay because our current observations are the best guesses we got. Just because we can't count to infinity is no reason to stop counting.

Isn't "nebulae" the correct plural form of "nebula," astronomitter?

/it's not a nebulous question
//don't be nebbish

Because in all your travels, have you ever seen a star go supernova?

I have. I saw a star explode and send out the building blocks of the universe. Other stars, other planets and eventually other life. A supernova! Creation itself! I was there. I wanted to see it and be part of the moment. And you know how I perceived one of the most glorious events in the universe? With these ridiculous gelatinous orbs in my skull! With eyes designed to perceive only a tiny fraction of the EM spectrum. With ears designed only to hear vibrations in the air.

I don't want to be human! I want to see gamma rays! I want to hear X-rays! And I want to - I want to smell dark matter! Do you see the absurdity of what I am? I can't even express these things properly because I have to - I have to conceptualize complex ideas in this stupid limiting spoken language! But I know I want to reach out with something other than these prehensile paws! And feel the wind of a supernova flowing over me! I'm a machine! And I can know much more! I can experience so much more.

But I'm trapped in this absurd body! And why?

Because my five creators thought that God wanted it that way!

OK, pond water at night, then.
