The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they reveal knowledge. They have no speech, they use no words; no sound is heard from them. Yet their voice goes out into all the earth, their words to the ends of the world.

No. A normal visible light telescope absolutely shows color. You can just point a DSLR with a zoom lens and no filters at the sky, take a picture of M42, and confirm that yourself.
I'm sorry, but the last time I checked a DSLR is not my eye. I have plenty of images from my telescope and various cameras. How you can conflate the 2 is beyond me. Comparing a long exposure from a digital sensor to what your eye can see is beyond bonkers and confusion of the topic at hand, or right in front of our eyes to keep it on subject
Before you jump to "bonkers" maybe give the people you reply to some credit- I'm an amateur astronomer with facts at his disposal.

#203Absolutely incredible. For a little bit of context for how impressive this is, here's my take on it with a consumer grade 8" Newtonian telescope from my backyard: https://www.astrobin.com/full/w4tjwt/0/

Maybe I misread your statement "Using a telescope to look at things, one only sees a black and white image". Certainly you can see color when looking at planets (mars, jupiter, saturn). But more importantly: you can see M42 in color with a telescope and eyes, it doesn't need to be a camera or film. If your point is that it's hard for your retina to detect a rich color spectrum from distant objects without either magn…
As am I, and any time I use an eye piece, it is nothing but b&w for DSOs even for something as bright as Orion's Nebula. The spirit of the conversation is if people can see the true color the way images from large telescopes posted in articles like this. They cannot. You take the reaction from the average person that has only seen processed images after looking through a telescope for the first time, and they will almost always have a bit of disappointment in their voice. I have taken my scope to rooftop bars and let patrons look through at whatever can be seen at the time. I have yet to do this and not meet someone that's never looked through a telescope with their own eyes--which is the point of my effort.

Buddhism is deeply rooted in reincarnation and the progression of a common person to an enlightened being through different ranks over the span of multiple lifetimes. I am pretty sure there is a dimension of life that we have yet to discover and learn about. And for the time being Buddhism is the only “religion” that openly discusses this progression. Hinduism has the same but in my experience it’s a lot more reserve…
I think any view of life consistent with its emergence by evolution isn't consistent with reincarnation, or certainly doesn't support it. But given the universe in total may be unimaginably larger than our observable universe, and the total universe may well be an insignificant feature of an unimaginably larger reality, its quite possible that versions of us appear in a fractal-like way, over and over across reality.…
Is this yet another one of those scientific facts that does not require a proof?
> Too many imaginative people and popularizers have a tendency to jump from actual equations/constraints they don't understand, to non-scientific psychologically motivated "implications" and ideologies.
Similarly, too many imaginative people who lack adequate depth in epistemology and non-binary logic like to practice both on the internet as if they know what they're doing. And the beauty of it is: if the minds of the population have been adequately conditioned, no one notices.
But wait, there's even more Oracle level soothsaying of the unknowable below:

My response is staying with science, which just means staying with evidence and reasoning that avoids our unbounded ability to fool ourselves. I.e. repeatable experiments by others, tested model predictions, mathematical and statistical checks, etc.
That is all science and math are. An accumulation of tools and systems that improve the reliability of our thinking. They increasingly help us mitigate our exceptional talent for fooling ourselves.
If we find another way to "know", it will get included into science too.

I'm sorry to be such a party pooper, but when religious or mystical people make epistemically unsound claims, the knives almost always come out for them, a little in the opposite direction shouldn't hurt too much. And besides: "science" claims to welcome criticism, much like religious people claim to follow their scriptures. But then, who doesn't like to have their cake and eat it too?

For demonstration, I always attach a DSLR to prime focus and display Live View.

But that's it. Life doesn't seem so unlikely, does it? There are things we still don't understand about it, but we understand some, and it's not magic. It can happen, given the right conditions, much like mold may grow on a piece of bread under the right conditions. What's difficult to comprehend is the immense vastness of the universe. It seems unlikely that nowhere else did the preconditions for life arise, and in…

We know a whole lot about ways life changes once it's there but we haven't observed life emerging from non-life and our hypotheses for how life emerged on earth has more holes than swiss cheese and it doesn't have to be magic in order to be exceed…
> but we haven't observed life emerging from non-life
But our laboratory is very, very small, so that proves little.
And we know life emerged at least once, and it doesn't seem particularly improbable. That's what I mean by "not magic"; not that we understand every little step, but we have some idea.
I don't think it's scifi to believe it's unlikely only Earth has sparked life. The one thing that is unlikely is that we will ever witness life anywhere else, but that's a different problem.
