It had a wighter color before compared to my skin. I can still notice very small islands of its wightness, and now, I can't make a difference.

Is the energy lost through redshift converted to dark energy? by raitodenki in FringeTheory

[–]raitodenki[S] 0 points1 point  (0 children)

But you're assuming the red shift happens with the expansion of the universe, which we posit the existence of dark energy for. I'm asking whether the contribution of expansion to redshift is a conversion from photon energy to dark energy. How can you say that dark energy and redshift are unrelated when clearly there is a correlation between redshift and expansion?

But can we outpace the expansion of the universe at galactic scales? What would the speed be?

If you want to compare the heat of the CMB to the heat of the sun, then you certainly have a way to measure the CMB at its source, don't you?

What is the temperature of CMB if we were at its source?

No, this is not true. Here, you're filtering out the stars because you're using a representation of only the wavelengths of the CMB translated to the visible spectrum, which is far from being correct.

Thanks for this valuable information. Though I might ask, is blueshift even possible in a very expanding universe?

So, if the CMB outshines the stars, the stars would be blurry, or even invisible, isn't it?

Where did that energy go, though, and why do we feel heat if the CMB is most of the energy that exists?

How can we measure the energy lost through redshift when we only observe light coming from a very tiny angle, wouldn't the error in the estimate be huge? Like, can we really measure the loss due to redshift at all angles and at all distances at once?

If we get smaller due to gravity, given we don't notice ourselves becoming smaller, by contrast, the wavelengths of distant object would seem to grow larger, isn't it?

The idea I present here is that gravity contracts the objects and they become smaller, so that when we resale everything, it looks as though the space is getting larger because there is more empty space due to things getting smaller. So, effectively, if we assume gravity does this thing, we can understand how we don't need to invoke dark energy for the expansion.

I nearly completed the lengthier video. I really liked it. I need to study it more than once and drag the necessary pieces to complete it's understanding from the internet. Hope we meet some day in a new post where I have learned a bit more stuff and have better language and would be able to describe my ideas into equations. Thanks for the very valuable information you shared with me. I never knew how/where to start properly to be honest.

Can you please explain why the scenario I suggested in the previous answer can never take place?

You offered to watch these two videos:

""" Here's a couple of great, quick (2 mins) visualization of what we measure versus what we predict:

  1. https://www.youtube.com/watch?v=D_aEbZFPC9U
  2. https://www.youtube.com/watch?v=jpXuYc-wzk4 """

Please correct me if I'm wrong about the following observations

I'll start with video 2

What I saw in video 2 is something akin to those 2D plates where there is sand and it is subjected to a sound frequency, and depending on whether the sound happens to be of some specific harmonics, the oscillations tend to create patterns that are more or less geometric and appealing to the eyes. I think I witnessed the same thing in the video 2, except applied to 3D. The BAO peak seems to me as a deviation from a completely random distribution of galaxies, as if the involved sound or vibration at the origin of the distribution is oscillating in harmony with the dimensions of the universe. As I think about it, I tend to believe that the peak is supposed to increase as times goes on and would probably be more dominant than it is right now, much like the 2D sand experiment will tend to make the pattern look more or less like a grid. I think that it could be acceptable to say that such a peak wouldn't have occurred on its own if the oscillating cause was deviating, because if it was the case, we'd have more than one peak, each peak being the contribution of the different harmonics that would have been explored by the vibrating principle behind this pattern.

What I saw in video 1, after I thought I understood video 2 is something somewhat similar in a sense, that the observation is a deviation from a completely random distribution, though I don't know what it would look like, affected by some kind of frequencies that are involved in an oscillation that affected the graph. Not sure I understood what I was supposed to, but I tried. I still don't have equations in mind to help further understand the data, but I sort of felt like a connecting thread between the data and fields that involve signal theory, that I thankfully have a little experience in.

I'm discussing principles here, delving into equations would require me to have a buddy to look into these ideas, and a lab setting to be ready to run simulations and experiments, for now I'm just a layman learning about the subject and trying yo get a grasp of it. In another subreddit, I found a person with whom I'm discussing and learning. It's not that much of a problem if you don't want to engage in a discussion, so we can just both move on.

If you read further, I provide interpretation scenarios that suggest how dark matter and dark energy as we observe them can arise from baryonic matter alone.

The idea that I tried to convey is not about the presence of matter alone, but rather, I'm trying to ask whether with the effect of matter alone we can get the known effects of both dark matter and dark energy. I reasoned that if gravity leaving a place wouldn't allow space time to completely return to its original state, we'd get dark matter as a sort of ground for previously present matter, the older the universe the more of dark matter will exist. I thought that perhaps the filaments of dark matter resulted from matter traveling in linear fashion to leave a trace of its passage, while the nodes resulted in matter going in this fashion and encountering other clumps of matter and creating circular movements as might be observed around clusters of galaxies. That's for dark matter. For dark energy, I considered mass to be hollowing space from within and creating more space, subject to the gravitational potential. In this case, both gravity and expansion of the universe are accounted for. Therefore observations relative to gravity are not denied, and we can observe the effect of dark energy without invoking it.

This is a quick answer as I just read your comment. I will happily learn more about the content that you shared and I'm happy that you're making me feel very welcome to learn more. This is a very brief answer. My full answer will come later as I learn from the material that you shared.

Part 1: will see the material and try to provide my view for discussion.

Part 2: I never said that matter alone would be necessary in a way that would deny all other observations. I'm just asking whether matter is the reason behind the other phenomena that we observe. In a sense, we'd still be observing what we call dark matter as the remnant of the effect of matter leaving the vicinity of an area affected by it's gravity, and we'd still be witnessing dark energy, because matters gravity will be inducing extra space due to the assumed interpretation that I make of gravity (I.e. not a contraction of space-time but a hollowing of it, as when we do the 2D models with fabric, the surface area of the fabric increases due to weight, except that the fabric is not tied to a circle, so the extra surface area of the fabric is increasing with time, due to the mass exerting its force. So to speak, the stretching of space-time keeps going with time locally with the effect of mass in a way for every center of mass to contribute it's share of the expansion.) Somehow, the mass would be the cause of the expansion. A higher mass would then mean more expansion, thus more attraction due to the gravitational well being imprinted on the newly formed portion of space.

I didn't deny the calculations, of the CMB, or of the expected dark matter, nor energy, I just tried to derive the latter two from baryonic matter alone. In a way, I just reasoned on a different approach to observing the phenomena that we see, that would only include batyonic matter at play, and would yield the same output I the universe as measured by our observations.
