Where Did Dark Matter And Dark Energy Come From?

Why would KZbin censor a legitimate explanation of Dark Energy in scientific terms? Why is it the people who claim to speak for knowledge and science are so afraid of the Truth they claim to be seeking?

[@ericfarina3935]

@@FortyBlack You are essentially on the right track. I posted a more comprehensive explanation in terms of relative physics, but KZbin censored me. I must be on to something...

[@ericfarina3935]

There is only one Truth: the Universe is Infinite. All language, math, and observational experience exists relative to eternity. That is why there is no limit to the information processing potential of linguistic or mathematical social constructs (future humans may well make base trillion calculations in their head. Imagine how that ability would change your perception of objective reality, and imagine that future humans after them may become even more intelligent ad infinitum). That is why our understanding of physics begins and ends with the Singularity. Future humans operating in tandem through some form of neuralink will likely develop systems for information processing and organization beyond our capacity to imagine, and all of our beliefs will seem foolish or at least obsolete. There is only one thing we can know for sure, one thing that is obvious: the Universe is Infinite. Everything else is speculation relative to observation relative to evolution.

In the late 1970s, as a university freshman, I attended a three part course, Introduction to Astronomy. I would have become an astrophysicist but I couldn't comprehend the academic politics, egos, etc. Intellect was not the problem. Playground rules were. I later learned that it is called autism. I attended a lecture given by a friend of my professor who explained this weird stuff she called dark matter. Decades later I was reading an article in the Smithsonian magazine and I saw the lecturer's picture. I have no expletives to express my astonishment when I realized that I had attended a talk, along with about two dozen other students, given by Madam Dark Matter herself, Vera Ruben. She was really nice.

[@fitz2917]

@@bangrojaiwhat does autism feel like? I’ve always wondered. Obviously you don’t notice it, unless you compare yourself to others. However always found myself being curious on what it truly feels like.

[@DefaultFlame]

@@fitz2917 Like you are born on an alien planet with an alien and, to you, completely incomprehensible culture. Everyone around you seems to be, from your perspective, insane, but since it seems to be everyone the conclusion is that your are the one that's on the wrong planet, not them. Alternatively, it's like everyone is playing a game, everyone except you got the rulebook to the game, and the game is played all the time for all the stakes. And you are told none of this. The punishments for breaking even what seems to be utterly insignificant rules can be absolutely massive. No one will tell you the rules, saying that they are obvious, or will even lie to you about the rules, or skip important caveats of or exceptions to the rules. Sometimes asking about a rule is against the rules and leads to being punished. Sometimes asking is not against the rules. Sometimes you can only ask a cetain number of questions about the rules before it becomes against the rules. Sometimes you can only ask about certain rules from certain people, or you will be punished. There is no way to know who you can ask, other than asking the wrong person about the wrong rule and getting punished. The only way to find out these rules that govern even the smallest and most insignificant thing in life is to break them, suffer the disproportionate punishment, and somehow figure out what thing or combination of things out of hundreds if not thousands of possible things you did, didn't do, did wrong, did at just slightly the wrong time, in just slightly the wrong order, etc lead to the punishment. And figuring all of these thousands of rules with millions of exceptions, caveats, and variants does not come naturally to you at all because none of it makes sense to you. It all has to be done actively, consciously, and by memorization, because to you there is no line of logic connecting the rules, they seem to uttely arbitrary. After literal decades of constantly trying to learn I can say from my own anecdotal experience, research, learning about psychology, animal behavior, politics, history, and so much more that there seems to be underlying threads connecting these seemingly arbitrary rules, but it's a muddled and vague mess made up of instinct, tradition, culture, and personal history all interacting in unpredictable ways and all smushed into a ball of utter chaos that tangled Christmas lights can only dream of aspiring to. If that all sounds exhausting, that's because it it. There is a reason autistic people tend to try to limit their amount of social interaction. Not because we don't enjoy social interaction but because it gets really, really exhausting having to constantly do mental math. Yes, you can get better at it, to a degree, and yes you can train some of it in as habits with enough years and effort sunk into it, that's what masking is, but it never truly becomes automatic as it is for other people. It always requires active effort.

[@mscbijles1256]

I’m a chemist, with nothing more than a fascination for the universe. But I find myself wondering whether additional dimensions could have anything to do with ‘the dark side of the universe’. Too small to measure them directly, but these dimensions seem to show their heads in a large and varying amount of things (including computational chemistry and the modeling of reactions). I just can’t shake the feeling that the thing we are missing, may not be truly missed or overlooked at all, but we just have to connect the dots (in a higher dimension).

[@farangtikitungmuang]

Lately I've been considering the idea of emergence such as how some very simple systems tend to organize themselves in strange and surprising ways. Chemistry emerges from physics and biology emerges from chemistry. And with the recent discovery of the Higgs boson we now have an idea about the emergence of a specific property of matter: mass. Suppose there are other "fields" which defy our current capacity to measure but nonetheless canalize lower order phenomena to "emerge" in higher order structures. Consider that somehow elementary particles exist and act in specific ways that earn them labels as quarks, electrons, atoms, etc. Where does the information come from that permits an electron to act the way it's supposed to act? Obviously elementary particles are what they are but their very being requires that they be imbued with information. Where does the information come from that distinguishes a proton from a neutron? Wherever that may be, perhaps some higher dimension or other, with which we can only indirectly interact, that information is as integral to the existence of the particle as its mass. So, could there not also be a dimension from which information that informs chemicals about how to form life derives? Suppose life is like mass and derives from a fundamental property of matter that is even harder to measure than the Higgs boson? Furthermore, life should also demonstrate periodicity the same way chemistry does. Which begs the question, what does biological life emerge into? Maybe AI?

[@winterroadspokenword4681]

As a deeply spiritual person who's discovered what appears to be a god that interacts emotionally with us; once you open up truly to your emotions and gives you insights you never knew you had...I fully believe that all of the dimensions of the metaphysical universe are the dark energy and matter elements of the universe. By all accounts of those who've channelled information, the metaphysical universe is far far bigger than the physical. For example, every animal that has ever lived that has a central nervous system also has a spirit body, that passes into be spirit universe, or rather, remains there, linked to earth and the physical universe. But expanding outwards and its growing too. Each time humanity expands and grows by connecting to god, it creates new universes in the metaphysical world...new dimensions by all accounts. I'm curious to see if this is paralleled in physically observable science!

[@kylewenzel537]

@@farangtikitungmuangwhat if the universe isn’t actually infinite? You seem to understand this better than I do but if dark energy is pushing the universe outwards, and it doesn’t dissipate then theoretically the universe can expand infinitely. However what if dark energy does eventually dissipate but the universe hasn’t been alive long enough for it to start dissipating. Since dark energy makes up so much of our universe if it were to dissipate it would take trillions of years to do so and then eventually the universe would stop expanding. I try to think of dark energy as the mozzarella inside a mozzarella stick. The universe is the stick and when you expand it the mozzarella inside becomes thinner but the closer you are to the stick itself the thicker the cheese is. Could it be possible that where we are in time is the equivalent to the thickest part of a mozzarella stick? It’s a really stupid analogy but it helps me understand this a little more and actually visualize what I’m trying to say. I know next to nothing about this but it’s fun to hypothesize.

[@farangtikitungmuang]

@@kylewenzel537 it is fun to hypothesize and I don't think I have much more insight into the reality of the universe than anyone else. Your analogy works just fine.

[@skepticbb93]

If we imagine the universe as a construct that is made up of tiny crystals that are "plank" size, the crystals may not fit perfectly together. So between those spaces maybe energy seeps in from a parallel universe or seeps out into an adjacent universe. If it seeps in could that be dark energy?

[@daf631]

@@skepticbb93 considering the Universe appears to be created generally in sphere shaped objects, that seems like a very good theory in my opinion.

[@airplayn]

I have read papers suggesting that quantum gravity may be a property of the quantum foam below the plank size limitation. I guess that's possible because the quantum "foam" isn't really "matter" and not limited to the plank distance in a similar way the "strings" of string theory may make up matter while they aren't material either just like the concept of quantum foam. For example, Matt Dowd at PBS Spacetime actually made me "think" I "understood" the "concept" of quantum gravity. Obviously all those "quotes" mean that without the equations all that I thought I understood might 'feel' right without full comprehension. "Wow, that all sounds pretty neat, doesn't it, Rover?" and "what did you think about that, Spot?"

Love this channel (and the Earth Channel too) and really appreciate these videos. However, I need to push back slightly on the assertion that Dark Matter can't be Black Holes. I'm no expert, and am only going on what I recently heard on Scientific American's Audiobook "Black Holes, Going to Extremes". There were at least a couple of quite recent essays that sited recent papers which claim Primordial Black Holes could still be a possible source, as the more recent hypothesis is that they could cover a range of mass/densities that would make their detection via gravitational lensing vastly less likely. Honestly, I'd need to go back and listen to it again to be clear on the argument, but anyway, just thought I'd mention it. Keep up the great work.

Cosmology has always been such a great comfort to me. My problems melt away and while I’m snot sure that I see design, I know I see beauty and mystery. Thank you for these videos.

Newton's laws were an approximation. Einstein's laws an approximation. Approximation of reality Huge steps for a collection of particles such as the human mind. That is part of the wonders we find ourselves in. It is only the optimists that is important, the optimists that sees reality and looks beyond This is, wonderful and exciting. Thank you for your work in bringing this together for all of us.

We barely know anything about space but what we do know is truly spectacular, a seemingly endless playground for discovery and exploration. The closest I'll ever get to exploreing it is Elite Dangerous and that kinda breaks my heart. I love Elite but would be completely fulfilled to be able to actually explore different star systems and their body's, different galaxy's and everything in between.

This is probably the best documentary I watched on this topic. Thank you so much for sharing it!

[@STaSHZILLA420]

I have a question.(well, a few.) Lets say you have just an Earth-sized planet in space. If the planet were to disappear instantly, how fast would it take for the gravitational effects to disappear? Would it be instant? Light speed? Would it sort of dissipate over a certain time? What would happen at the place where the center of mass used to be? Thanks in advance.

[@bobman929]

Gravity moves at the speed of light. And thus the effects would disappear at the speed of light.

[@SamSung-qy5hj]

Above is not proven yet! It is based on very inaccurate measurements of gravitational waves. I think gravitation is part of the underlying structure of the universe itself. Call it a constant or ether or as you will. So I postulate that the earth would fly free faster ("instantly ")than the 8 minutes the light takes to travel the distance between sun and earth, if the sun is somehow magically to disappear. Could be I'm right or wrong. Probability dictates we most likely will never find out.

[@gammakay521]

@@SamSung-qy5hj If gravity travelled faster than the speed of light, then we could detect when a macroscopic object has moved based on its gravitational effects faster than light. As that breaks the postulate that information travels less than or equal to the speed of light, then it cannot travel faster than light.

[@martinwillemse8923]

They say it goes at the speed of light, if it does then the light could escape from a black hole because the light goes at the speed of light and gravity can only speed it up because gravity is too slow, we so could assume that the gravitational force is a direct force and it is instantly gone, leaving a vacuum and objects trapped by the gravitational pull will then shoot into space.

[@mudbaeley9199]

Idk why people are telling you that gravitational waves don’t travel at the speed of light, but they do. It would take eight minutes for earth to realize the sun had disappeared- not only because of the sudden darkness, but because that’s the moment we would be flung into space and become rogue.

It’s truly amazing that Einstein predicted dark energy 100 years before it was discovered. A man truly ahead of his time.

[@knuckle12356]

Have we discovered it? I thought that we've only found evidence that it >MUST< exist, inferences based on behavior observed indirectly to affect the universe and its constructed form as we claim it to be today. But we haven't captured, created, or directly observed dark energy, right? It's just a place holder for math equations that don't work without inserting some balancing forces. And those adjustments are referred to as dark matter and -energy. Are you saying we have captured/ identified dark energy through direct observation? Or just that we have confirmed something to be real, which used to be just a proposed thought experiment...? Curious to read your answer. Cheers. 🎩👌🏻 💩 ~Lord Shitly of House Fæces.

The non-observable mass and energy could belong to other dimensions that we do not access at this time.

If higher dimensional matter exists then we should’ve at least discovered a 3d shadow of one

[@pluxauag7555]

Einstein may have pondered a possibility today, does Dark Matter come from Dark Energy, where in the same way Dark Energy may come from voids. The answer to these two dark states and understanding the deeper make up could explain the Universe in equations much better. We learn everyday. Will the universe expand forever or is this a snapshot of a dynamic universe which could change over billions of years, which brings us back to the question, does dark energy create dark matter? Great video keep up the great work and the years to come will give us so much more to learn and understand.

[@jimgraham6722]

Or dark matter a decay product of the inflaton, decay in turn to dark energy.

[@kenadams5504]

I though a tiny amount of dark matter is thought to have instigated the Inflation ...which implies dark energy came after dark matter.

[@jimgraham6722]

@@kenadams5504 I think most agree before inflation there was no matter, just energy of incredibly short (basically Plank) wavelength. Matter and most of the fields that constitute the universe were therefore emergent from the inflationary period.

Amazing documentary. I knew you had to be a PhD astronomer and turns out I was right. Very well written/researched. And yes, I do believe dark matter and dark energy are related somehow.

[@SverreMunthe]

Every time I see a video about dark matter and dark energy it's like watching a show by a magician, and most physicists in the world sit there and applaud and try to figure out his tricks. 10-15 seconds, at the end of the video mentioning the most interesting , and probably only, solution to the magicians trick, gravity. We have placed Einstein on a pedestal and anyone who even thinks of questioning his discoveries are looked upon as heretics and blasphemers. We still trust the man who refused to believe quantum physics, and called it playing with dice, more than anyone else.

Thanks for keeping it to the science. I usually don't watch the basic level material because it's usually sensational pseudoscience schlock, but your videos are different. Really appreciate you staying within the bounds of real science.

@@SuperFluidFerroFluid theory is a part of science. What's not science is misappropriating pieces of theory to fit a specific narrative. For example, there are a lot of channels using quantum entanglement as a launching pad to all sorts of ridiculous speculation.
