The same thing everything else came from the SOURCE , lol , that God particle is the combined force of light and dark energy , dark energy on a small scale is the firmament aka ground in which to fertility life in all realities aka planets
The light is the life force , in which is connected to all creations , when that dies all will attract backwards or however it decides , all things are solid matter , in a huge conscious , collected ideas , or ones ideas come to a literal reality , wow ...
Why would RUclips 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?
@@FortyBlack You are essentially on the right track. I posted a more comprehensive explanation in terms of relative physics, but RUclips censored me. I must be on to something...
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.

🤣🤣🤣🤣 i was bright at high school but i was doomed in college. Autism wasnt the thing in late 90's. It was too late for me. Soon after my medical condition was detected, it was too late to go back to chase my credit. I was kicked from engineering because i couldnt do good cooperation in lab job.
This + PBS Spacetime are probably the best physics communicator channels out there. Got a special place for Crash Course too, but their Chemistry series was the best series.
I studied astronomy in college, always found fascinating, yet scary. I enjoy this channel. I enjoy the new findings.
This channel never ceases to amaze me. The quality is absolutely phenomenal, I can't believe we get this kind of content for free!!

Thank you for presenting the information on this topic as factually as possible. So many other video makers delve into wild speculative physics or outright fictional comparisons to try and draw an audience.
Truly, the most compelling thing about these topics is how much we DON'T know.
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).
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?
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!
Exactly what m theory says
@@76rjacksonwhat 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.
@@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. Your point is clear and I think it's a good one. Keep thinking outside of the box! I mean, we already knew that the moon was made of cheese....lol!
Another absolutely first class documentary! I love this channel so much. The rest of RUclips may as well not exist as far as I'm concerned.
His documentaries are better than anything on National Geographic or the discovery channel.
Absolutely !!! 💯% Couldn't agree more , or put it better ! 👍🏼
@@oldmechanic5744 what?
@@oldmechanic5744 🤭
as youtube inflates exponentially, we will only be left with this channel... and then someday, just this video 😂
I learned so much! Wonderful mind expanding content. From the music, editing, to the intelligent commentary. This is better than 99% of documentaries big TV networks release nowadays!
I love this series. It is super awesome, and I find myself watching them over and over.
The docs are the best I think I have ever had the privilege of watching. They are written so well. The narrator is perfect. Please don't stop. You answer all my questions. Great job 👍 keep it up!!!!!!!!!!
You guys are so good...and no fake ass robot voice...wonderful as always....MUCH LUV FROM N.AUGUSTA S.C
I don't know if this channel's documentaries make me more in awe of our universe or mad/sad at how little we actually seem to know about it.
Great work as always!
I sometimes wish I didn’t know that the solar system will end… the universe will go dark…. Like billions and billions etc years from now…. absolutely no effect on myself or anyone I remotely know… yet it makes me sad. Despite the human condition……. Life really is beautiful.
Be happy that we know as much as we do. It wasn't that long ago that we knew nothing.
Try being drunk it's really epic lol
We know more about space that we do our oceans 🤦🏽♂️
@@Srsbzns_5150 Seriously! There could be who knows what in there and we might never know! Kinda crazy.
I’ve watched a couple of your videos, they are amazing! You really know how to make interesting videos. You are also very good at explaining what seems to be very complicated subjects. Thank you :)
Just want to say thank you. All the work that goes into this, making freely available. Very much appreciated
This is the best presentation of modern cosmology that I have yet seen. Thanks.
Best channel on RUclips for space.
The invention of internet and accessibility to the remotest part in this planet we called Earth looks a diamond find. The priceless documentary of this channel appears gold in our knowledge. But as the saying goes life changes thru birth, growth, decay and death still we treasure this kind of information thru the access of internet. I cherish this kind of valuable documentary.
I would've never imagined that I would learn so much while going to sleep! Excellent channel!!
The concept of these mysterious components of existence is so intriguing. Thank you for such an excellent video.
The question of what is dark matter and dark energy may possibly be answered in part by researching whether the Plank is truly the smallest unit of measure in the Universe.
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?
@@skepticbb93 considering the Universe appears to be created generally in sphere shaped objects, that seems like a very good theory in my opinion.
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?" LOL My chemistry and biology degrees from the 70's were a little light on the wave function equations, but that might just be why I didn't do so well in P-Chem. My prof really liked me and let my lab scores scrape me through ;-)
Look up nassim haramain (I think that's his name) he has a very solid theory in my opinion
@Science Revolution : I think you forgot to take your medication. The things you've said are complete nonsense and most can be disproven within seconds by examining readily available data.

Love the narration and the narrator's voice 😅👍
It’s because it is relevant and always will be. This is us how we came to be who we are. It is always going to be a mystery until it is solved. But maybe we aren’t to know yet,we have limits. Maybe we need to figure out what we know first before we continue to try to figure out what we don’t know.
Excellent video! Pretty comprehensive. Not just a re-hash of the more common and established notions.
Through this vid, I've been introduced to new (to me) terms and concepts. I'm going to have to watch it again several times to fully absorb it, and even then, I might not. But at least I know now where to look for a greater understanding of the current state of cosmological knowledge and theory, and what the right questions to ask may be when I get there.
Thank you very much! 🙂👍
This is probably the best documentary I watched on this topic. Thank you so much for sharing it!
@HistoryOfTheUniverse Never stop making these videos. You inspire us. You educate us. You encourage us to look upwards and forwards to the advancement of humankind and to better find our place in the universe. To ask questions that others are afraid to know. To understand that with everything, no matter how complicated, they is an answer, an explanation to it, even if we don't know it YET! Knowledge is indeed Power!
I feel as though I can't rest until these things are known to us haha...
I have to say, this is one of the most comprehensive presentation I’ve seen on the entire evolution of the universe and our understanding of it. Oh yes, btw, enjoyed the 30 note sound clip of Cannon in D. :)
I would not rule out primordial blackholes , let’s suppose that sufficient dark matter is present , the end effect is no distortion in light , the light would be curved in virtually all directions throughout its voyage resulting in zero gravitational leasing at the destination.
I heard the first two notes and already knew what it was. Fortunately it didn't go on long enough to get annoying.

Another excellent episode, keep up the great work
The expanding universe might represent a Turing reaction-diffusion system. Turing conceived his reaction-diffusion model to explain biological complex structure, theoretically by interaction between a long range inhibitor exerting negative feedback and a short range promotor exerting positive feedback, as discussed by Kondo and Miura, 2010. Basically two agents with different distance scales and opposite effects. The result is emergent pattern like the dots and stripes on fish and land animals. In the expanding universe dark vacuum energy drives expansion over vast scales while gravity attracts object together over shorter distance. This looks analogous to the two opposing forces in a Turing reaction-diffusion system - the long range negative feedback (dark energy pushing apart) and the closer range positive feedback (gravity pulling together). So the expanding universe will inevitably be a Turing reaction between these two opposing and differently scaled forces, causing complex labyrinthine emergent pattern - this is what happens with the universe’s filamentous structure.
interesting as a sort of model, possibly, but what can it tell us that existing, perhaps-better models cannot?
weak force and strong force have been proposed to share such a system and maybe matter simply are a system of such.
@@xBINARYGODx that structure can be emergent. It does not all have to have pre-existed in the early universe. This impacts the whole uniformity question.
Self Regulated Pattern Formation. DNA? No. Well I would argue it an Untestable Theory. So Not Even Wrong.
Just a quick comment to congratulate you on the quality of your videos.
I must also add that in addition to the visual quality - your narration takes everything to another level.

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.
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

Friends !? I couldn't stand your twaddle two minutes
@@TNT-km2eg There's no need to be mean in response to friendliness.
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.
Gravity moves at the speed of light. And thus the effects would disappear at the speed of light.
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.
@@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.
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.
@Martin willemse gravity traps light in a black hole because of pulling the surrounding space-time fabric into it. It’s not gravity pulling the light in, it’s light being unable to escape the curvature of space-time.

Thanks for the excellent material!

Excellent. Very well presented, and an excellent commentary.
