Awesome video. Loved it. Just one thing, I was wondering why birds chirping were added to the background music around 0:36. Space birds flying threw the nebulaes? *Nothing can quite compare with simply looking up at all the shimmering stars studding the vast dark blanket of space, all through the glass roof of my spaceship, while listening to the birds twit n sing.*

Incredible video! I'm so pleased to have subscribed!

I used to have a Celestron C-8 telescope, and by far the most colorful object I ever observed was the Orion Nebula. Just astounding reds, blues, purples. Far more colorful than anything I observed in our solar system (everything but the Moon required long photo exposures to get full colors and detail). Goes to just how much energy and scale nebula have. I was awestruck. I 'think' you can even see it with ok binoculars on a clear, dark night away from city lights.

Most assuredly could give the wrong idea across. Personally, I found that comparison to be more confusing than helpful. I was hoping he would compare a cubic centimeter of cloud matter ( Obviously a rough estimate, as the particle count varies greatly in clouds.) That would have made a lot more sense, since he had already compared the 2 just seconds prior to the chosen comparison.

Are those gases opaque when hot or compressed? Are there huge transparent gas clouds somewhere, and how could be detected?

You might have mentioned. Hubble pictures start out as shades of black and white. Individual images from Hubble's cameras retain no color information as such, other than the color of a filter, which selects a range of wavelengths from the full spectrum of light. A black and white (monochrome) image most realistically represents the range of brightness in such a single image. Just a little clarification.

When we die our souls live in the nebula. The RGB one was mind numbing.

what something 'looks like' depends on the eyes you possess, how sensitive and what wavelengths they detect. So, one could say that IS what they look like, but not how our eyes would naturally perceive them.

When and where does size start or begin that determines the size of the rest?

@binra3788

4 жыл бұрын

Your straight answer would likely be 'atomic weights' from which one then extrapolates larger masses - in a ball park way. Size as volume is - I feel - on shaky ground because some ideas are sacred cows that everything else has to fit - like redshift as a determiner of distance. IF we have any error in the foundation - it amplifies in the model. What price consensus? Size is volume - but do you mean mass or density or all at once? We set our datum point for bigger and smaller. The infinite in the infinitesimal is an ancient idea of the One in the Many and the Many in the One - which in scientific terms might be 'holographic'. But size is relative along the scale of its polarity. Is it our model that confines us - while also serving a purpose? The mind-body split led to Universe as Body (matter) and a self-alienation that cant find Home in it.

@Dragrath1

Size is a quantity our brains use to assess our perspective of the universe indicating some relation to causality. The best understanding is probably the current SI definition of a meter. "A meter is defined as the length of the path traveled by light in a vacuum in 1299,792,458 of a second." In short in science our standard units are defined based on the fundamental constants of the universe but it should be pointed out that space and time as we understand them are computations of the brain based on sensory information in order to convey enough information to survive long enough to reproduce and pass on our genetic material via evolution. They are in no way guaranteed to represent the universe accurately. Quantum mechanics does however provide a minimum knowable scale with plank units based off the uncertainty principal of quantum mechanics

@binra3788

​@@Dragrath1 You may notice that we have shifted to non human constants. Size is simply relative. because science is extending our mind to non human reality that requires precise mathematical definition - we need the new ways of defining - but we also need to bring it into human significance rather than use it as a leverage to invoke human insignificance. There is a sense in which we are nothing - of ourselves - and yet we are NOT of ourselves - but are each and together Perspective within Existence - regardless the contents of our mind or the use to which we put it.

It may be that constants are relational coherencies that may not under all conditions have a constant numerical value, the belief that they must be a fixed constant value would dictate any variation to be error. I see the formless or non local and non physical as 'qualities' with the expression into quanta operating a reflective sensing perception that evolves or unfolds as consciousness - but not as we define it for ourselves in terms of a dissociated sense of self that can imagine and play out options without having to act them out as part of its 'relational expression ' OF its Environment - which is Qualitative self-recognition - in formation or in structural and functional relation that holds a certain self-sustaining framework for development.

Nebulae have colors, the problem is that the only way you can see the colors with any clarity or brightness is with the intervention of technology (long exposure photography and post-processing). If you were to go out into the Universe with nothing but a spacesuit and your own two eyes, you would never be able to see all of those sights and colors. Our eyes see such a limited part of the light spectrum and they aren’t very well adapted to dark environments. And the distances in the Universe make it impossible to ever get close enough to see any of these structures in such impenetrable darkness. So the Universe to the human eye is unfortunately way too big, way too dark, and not so beautiful.

These gases are ionised plasma that makes up about 99% of the physical matter in the Universe. The electrical force is about a billion, billion, billion, billion times greater in magnitude than gravity - and the volumes of what we call 'space' are likewise vaster than our general human comprehension. The contributions of plasma physics to a new understanding of the Universe are to a significant extent blocked or pushed out by gravity models. However, those who align in the new perspective do not have to make lots of dark fudge and very silly conjectures as to why nothing is as the model predicted.
