I see a bunch of lines but it’s really just scientific interpretation of data. It’s not real things second question is why in the world they call of the axis of Evil You went over in the video, but never bother to explain why such an outrageous name.

Just past the 10 minute mark in the video she states that the dipole is “exactly” 90 degrees to the quadrupole and the octipole. My understanding was that the angle of the dipole is accounted for by the direction of travel of the Milky-way. It seems to me then that the mystery is really what possible reason could there be for these higher order poles to be at right angles to our galaxy’s direction of travel. 🤷🏻

I mean, we are sorta really special. Take our star, G-Class, but unlike other G-Class stars, ours is freakishly calm (this is a very big thing not many mention). Then there's the Sun's position within the Milky Way galaxy, which places it in the galactic habitable zone. Then our actual solar system has not one but four gas giants acting as cosmic vacuum cleaners, protecting us. And then we've got our planet, which is positioned in the perfect spot for habitable life to form. And then our moon is perhaps one of the most bizarrely useful moons in the entire solar system. If our planet were a lottery winner, it would have won the jackpot multiple times. It's really quite improbable that we should even exist.

I fear there's a lot of reaching going on here. Our star is relatively stable - at present. It wasn't cooperative to life when it was young (although life managed anyway) and absolutely won't be cooperative in the future as it grows old. It's already well on its way to becoming too luminous and active for Earth's atmosphere to cope with and in about 250 million years the biosphere of the planet will begin to collapse as a result. A billion years from now and the surface of Earth will be sterile. The sun's "galactic suburbs" position in the Milky Way is shared by about 100 billion other stars and probably a trillion planets so is hardly remarkable. Nobody would bother to look for life in the Galactic core for instance because conditions there are extremely hostile, both to life and to astronomical observations. We have yet to determine the "standard" form a star system takes (if one exists at all). Exoplanet research has a rather skewed sample data built in due to it favouring systems conducive to current methods of discovery. Detection methods have extreme difficulty seeing small bodies and pretty much no ability to see distantly orbiting bodies, so these are massively under-represented. So whether the solar system's layout is atypical or not is currently unanswerable. Also the "vacuum cleaner" hypothesis is a bit old fashioned these days and the situation is a bit more nuanced. Some modelling suggests gas giants create more problems to terrestrial worlds than they solve. I'll grant you the Moon is impressively useful in its current configuration (although it would have been an unholy menace in its early days when whipping around the Earth in 9 days). However there's no reason to believe the Earth would not be able to support life without it. Only that life has taken advantage of its presence. Don't forget that you are Douglas Adams' "sentient puddle" marvelling at how the hole it fills up fits its body shape so perfectly. Meanwhile an objective observer understands the puddle can _only_ take the shape of the hole it fills. It has no choice in the matter. Likewise we have the life cycles, morphologies and chemistry on Earth that this environment, time frame and locality in the cosmos makes possible. To assume this is the only form and only way in which a biosphere can manifest is at best only a guide for finding "Earth analogues" and at worst comically arrogant and near guaranteed to be wrong. For all we know life exists on hundreds of millions of worlds, many of which are likely to be far removed from the conditions here. But at present we do not know enough to answer the question one way or the other. All we can know is that life exists in the Milky Way, because we are a sample of it. A sample set of 1 tells us only that it _can_ happen and little else and a lottery with only 1 ticket isn't remarkable at all.

The more you know, the more you become aware of the things you don't know. Imagine our knowledge as a sphere inside the space of the unknown. If the sphere of our knowledge expands then so does its surface, the things we're aware we don't know. To quote Marcelo Gleiser: "As the island of Knowledge grows, so do the shores of our ignorance -the boundary between the known and the unknown. Learning more about the world doesn’t lead to a point closer to a final destination but to more questions and mysteries."

It's always why we think that life can only emerge on Earth-like planets. Until we either figure out how life can emerge under different conditions or until we meet other observers, it will remain an unsolvable principle.

A small remark for the graphics displaying the axis. The cosmic microwave background comes from all directions and is measured as a sphere around us. In 2D the sphere is displayed using the mollweide projection (the ellipse). The mollweide projection preserves the areas of parts of the sphere but it distorts their shapes and angles. This means that a straight line across the sky or on the sphere isn't straight when using this projection. The exact way to draw the axis is in form of a curved line or by just using a different projection.

Massive Missive (c) follows: (no TLDR - Lump it.) The same problem when plotting a shortest course, I.e. a great circle route, on any flat map of the spherical earth. Only a very restricted subset of true great circle routes show up as straight lines on any given flat mapping of the global surface. The rest are curved, even crossing “hyperspace” by leaping off one edge of the map and reappearing on another, like those video games where you can shoot at an opponent nearly the complete way across the screen from you by turning and firing from a very short distance at the proper angle to the edge near you and have the projectile/ray/whatever emerge from the edge very near them, doing them in promptly. Wraparound. You are never more than half a ‘screenshot’ away, in some direction. Another analog is in drawing threads on a bolt viewed at right angles. The simplistic way is diagonal straight lines across the axis of the bolt, but in reality the thread roots and crests are properly visualized as slight ‘s’ curves, with the extreme ends of the lines curved to a parallel with the bolt axis. You are mapping a cylindrical object onto a flat surface. A slight, but I think very germane, emendation to your ‘small remark’. Not only are we, as here, mapping the sky onto a flat two dimensional surface, but the sky is itself a spherical 2-D surface mapping of a 3-D volume to start with. That is the very concept of ‘the sky’. A straight line ‘on’ the 2-D, albeit curved, sky is not necessarily a straight line through either Newtonian or Einsteinian space. Planetary orbits appear straight along the ecliptic, but are elliptical in space. A lack of understanding of ‘mapping’ may be at the core of flat-earthers’ confusion, both on the ground and in space (for those who are truly confused, and not merely knot-headed contrarians). One of my brothers-in-law was impressed by my sister’s mention of some astronomical object as being ’out there’, rather than ‘up there’, showing that she understood the three-dimensionality of what was visible overhead at the moment, and earth’s inclusion in that volume. “or by just using a different projection”: This would require reorienting each projection’s axes to place the line in question along one of the small subsets of lines straight in both space and its mapping. A case of special pleading? What if, as here, you have multiple poles to draw lines for on the same map? This arbitrary reorientation tends to militate against the very point of mapping, which is to highlight relationships between multiple entities within a particular framework using an appropriate projection. I hope this has mapped the concepts, which I am trying to communicate to you, onto/into your mind - in full fidelity.

Answer is simple: all stars synthesize all elements; fusion happens in the outer layers of stars, not in the cores, and fusion is not what powers stars, but is a powered process, powered through electrical energy from huge interstellar and intergalactic currents.

This is actually a contradiction that I see pop up regularly in physics explanations, For example: "The universe is 3.8 million years old. The visible universe (or often just Universe) is 90 billion light years across". So if the visible universe (past light cone) is 13.8 billion light years across. Where does 90 billion come from? OK, they estimate the expansion of where the furthest object may be "now", except there is no "now" in the past or visible light cone, and objects outside of the light cone are unknown to us. Unknown such as the actual size of the universe. > In relativity we are always the center of our visible light cone/sphere (knowable universe). You perceive a different visible universe so I can never have a direct knowledge of what you see :) > [Edit - correction] What we refer to as the observable universe was 84 *million* light years across at the actual time of the CMB, NOT 13.7 billion x 2. The 13.7 billion comes after adjustment for inflation.

This is what baffles me. We're not the center of the universe, we're the center of OUR universe. That being said, by what we know and observe, we'll be able to find the center of the universe? Since universe is expanding, where is the point it's expanding from? I know we can't (maybe) pinpoint that accurately like with an explosion, since the scale of universe at the moment of big bang would be incomprehensible since even if fully compacted and opaque it would, for sure, be bigger than the most massive star discovered (or even, in my opinion, the size of a BIG galaxy), after the big bang our area of where Milky way starts to exist would end up way off the "center" of "explosion", could we will ever find a "center" point? I know I didn't explained that too good, here's another easy way to understand what I think of/about: Imagine a balloon, slightly inflated, just so that is looks it has some air in it keeping it "stiff" (This is how imagine universe before big bang. Then big bang happens, everywhere, starting this expansion (now imagine you're filling up this balloon with air to it's almost max) If, let's say, where the Milky way exists now is 3/4r distance from the center of the balloon (1/4 away from the edge or the balloon itself) but our observable universe it's only as big as a soap bubble in that balloon that doesn't even come close to the edge of the balloon, can we find a starting point of our position? I find this idea a very tricky one and can't stop thinking of it, since I didn't find anything to answer me this question. Not even the question of how far out are we from the big bang origins? Or how far out are we from the center of the universe. Or even if we know where this center is/might be. Or even how much is our observable universe compared to the whole universe?

@@axle.student The universe is 14.3 Billion years old or some where there abouts. Yes the visible light cone amounts to about 90 Billion light years in diameter which is roughly 45 Billion light years in any direction. We do not see 45 billion light years away though. We just see light that was emitted from an object 14.3 billion years away when it was 14.3 billion light years away and due to the red shift we believe it to be 45 billion light years away now. 45 billion light years on both sides of us is 90 billion light years diameter. Does that help reduce the confusion?

And the Lord God said unto Moses: For mine own purpose have I made these things. Here is wisdom and it remaineth in me. 32 And by the word of my power, have I created them, which is mine Only Begotten Son, who is full of grace and truth. 33 And worlds without number have I created; and I also created them for mine own purpose; and by the Son I created them, which is mine Only Begotten. 34 And the first man of all men have I called Adam, which is many. 35 But only an account of this earth, and the inhabitants thereof, give I unto you. For behold, there are many worlds that have passed away by the word of my power. And there are many that now stand, and innumerable are they unto man; but all things are numbered unto me, for they are mine and I know them. 36 And it came to pass that Moses spake unto the Lord, saying: Be merciful unto thy servant, O God, and tell me concerning this earth, and the inhabitants thereof, and also the heavens, and then thy servant will be content. 37 And the Lord God spake unto Moses, saying: The heavens, they are many, and they cannot be numbered unto man; but they are numbered unto me, for they are mine. 38 And as one earth shall pass away, and the heavens thereof even so shall another come; and there is no end to my works, neither to my words. 39 For behold, this is my work and my glory-to bring to pass the immortality and eternal life of man. 40 And now, Moses, my son, I will speak unto thee concerning this earth upon which thou standest; and thou shalt write the things which I shall speak. 41 And in a day when the children of men shall esteem my words as naught and take many of them from the book which thou shalt write, behold, I will raise up another like unto thee; and they shall be had again among the children of men-among as many as shall believe. 42 (These words were spoken unto Moses in the mount, the name of which shall not be known among the children of men.

Using Occam's razor, it's most likely to be data artefacts from our solar system, probably microwave (heat) sources in the Oorth cloud, dust too small to detect but too bright in their totality to not affect the CMB. Our maths are not nearly as advanced as we often think. For instance, in most CMB images, when putting them side by side with pictures of our galaxy, we can see some artefacts which match, despite best efforts to eliminate them. Some methods are likely to be circular: remove potentially closer sources of microwaves until the distributions are correct. A very dangerous method which can lead to overlooking actual distortions in the CMB.

Maybe the gravity could also be explained by preons that forms quarks and fill the vacuum, having more density where there is more mass and looks like curving the space-time, and having less density between the galaxies where they create new space-time coming from the transformation of mass into gravitational energy in the merging of black holes.

@@gamelairtim That is causing you concerns? Take a universe. Fill it with a plasma with (almost) exactly the same composition, temperature and pressure, then leave it expanding (at the same rate, in all places. Come back after it has been cooling for 3 minutes less than 300,000 years and measure the temperature here, there and over there (all pairs of them separated by more then 300,000 light years, so light, gravity etc could not have got from one point to another (this is the so-called "horizon problem") in the time you've been waiting. At that time, none of the gas will have dropped below the temperature at which hydrogen nuclei can hold onto an electron to become hydrogen atoms. Come back 5 minutes later. The universe, in these separate locations unable to communicate with each other will have cooled slightly, and the hydrogen ions are starting to combine for the first time to form hydrogen atoms. Photons are travelling further before encountering an electron (or proton) to scatter off (hence the CMB's alternative name of the "Last Scattering Surface" and variants). The same event has happened simultaneously throughout the universe, without any surprising coordination. How to get a universe "with (almost) exactly the same composition, temperature and pressure" is a good question - for which the standard answer is "inflation". What happened earlier is another good question (see Weinberg's excellent "The First Three Minutes"). But you make me wonder - shouldn't we also see a "scattering surface" from when the first electrons hooked up with He2+ nuclei to form He1+ ions? With He's double charge, that should have been at higher electron energy - so, temperature, so earlier. Can't we detect the light from that event? And similarly, the (red-shifted) gamma rays from the "freezing" of nucleosynthesis in the "first three minutes" at about six hydrogen nuclei to one helium nucleus?

Yeah from what I've read it seems that the way we originally derived the local momentum of the solar system was through use of the CMB dipole which if true would put this as an example of circular arguments. At the very least it has been well demonstrated in the last 3 years though a falsification test proposed in 1984 that compares the CMB dipole to a sufficiently large dipole built from cosmologically distant sources across the sky and checks to see if they both match as would be expected if the dipole is entirely or primarily kinematic in origin. The results from Nathan Secret et al seem to show that there is a 4.9 sigma discrepancy between these two dipoles which can not be rectified with the validity of a purely kinematic dipole falsifying the cosmological principal out to redshifts greater than 1if a single large statistical anomaly exists or the observable universe otherwise We need an independent test of the local frame of reference to verify that this is the case but to me it looks like a strong case for systematic bias as the culprit. This has the nice coincidence of simultaneously resolving the observations attributed to "dark energy", as an inevitable consequence of gravity in a inhomogeneous and anisotropic universe according to numerical modeling of the full unreduced Einstein field equations, the so called axis of evil discussed here, and the Hubble tension, not to mention the numerous and ever growing list of "impossibly large structures within the lambda CDM model" observed. The amount of problems which go away as a con sequence of systematic bias seems like Occam's razor points in this direction of faulty model assumptions.

I really struggle with the Cosmic Background Radiation. It implies that when it was emitted, it was 14 billion light years away (give or take) in all directions, implying a minimum size for the universe at that time of 28 billion light years across, and yet this was emitted within the very early universe, so the universe expanded at a rate way more than the speed of light, and yet we know that things cannot travel faster than the speed of light. I know that the “answer” is that it is the cosmic inflation period in which spacetime itself expanded at a ridiculous rate, and then mysteriously stopped, but I just cannot get my head around it. It just seems like a theoretical “fix” which is divorced from reality. I’d love you to address this in a future video as your explanations generally have great clarity.

As a lay man, I tend to snigger at the memes "curves the space-time" and the Lorentzian transform acrobacy, and the "expansion of the universe" - no science youtuber has ever cared to explain the very basics: speaking of "curving the space-time" or "expansion of the universe" - do the theoreticians imply that A) the cartesian coordinate system itself, the foundational theoretical framework, becomes twisted, i.e. no longer orthogonal, or keeps "sliding under our feet" to make the universe expand or B) do we somehow switch to using an "effective space-time", twisted and bounded by the speed of light, which departs from the ideal coordinate system, while the ideal coordinate system obviously stays put (albeit with a relative origin), exactly because it's perfect / ideal by definition? Thus allowing us to "watch the effective space-time" twist and turn, and expand. The expansion means that objects are getting further apart, but e.g. their individual dimensions remain valid, scale of distance remains constant, speed of light can actually be fathomed as finite etc. And another mystery to me: so let's accept as a fact that the big bang happened. Initially, the space was filled with matter, condensed to some "unimaginably high" levels of pressure / temperature / density, and then, it expanded. The question to me is: *where to* did it start to expand? In an ideal coordinate system, ignorant of relativistic stuff, there would need to be a "difference of pressure" between different places. Inhomogeneity. Otherwise, the ultra-dense and ultra-hot and ultra-pressurized matter would just retain its state! It would just stay put. Also, if we can already infer the rate or gradient of expansion, and we probably know the density of matter, isn't that already enough data to calculate the "size of the ultra-dense blob that went bang" (in a space filled with less density), or the "approximate dimensions of the domain of inhomogeneity" that allowed for the bang to happen? Or, do we really believe that the twisty bendy relativistic spacetime is the only coordinate system that we have, and it could start out "infinitely folded unto itself" and is merely unraveling to this day, at the speed of light? (I'm not asking if that difference makes a difference :-) Also, if mass was extremely dense (at the start of the big bang), but ideally homogenously dense over infinite dimensions, it would not form any particular event horizon. Also, an event horizon needs to be centered around something. Yes it can be deformed by inhomogenous density of mass inside (if we permit anything other than a singularity at the center) or by rotation... Seems to me that if the big bang did happen, and a cartesian coordinate system is applicable at least in theory, it means that the bang started from a blob of matter of finite dimensions. "Unfathomably large" is a silly term. Having a floating decimal point at our disposal, it's either infinite, or fathomable :-) It's similar to the evolution of theories around electromagnetic field and waves. At school, you are initially taught that there is no "ether" for light to travel in. The EM field itself is the "medium", in which fluctuations travel, and somehow the speed of light is a constant, characteristic of the medium. So, no ether, but we already have a medium. And then you get an accepted theory of the "quantum fields" and "vacuum fluctuations" giving rise to subatomic particles... But nooo, no Ether, that's been disproved centuries ago :-) In my book, it's just word play...

the expansion means, the light didn't travel. The expansion also means it doesn't need to expand faster than light for example.

Of course we're at the center of our observable universe, every point the universe is at the center of its observable universe. JADES-GS-z13-0 is the most distant galaxy we're currently aware of, and if there's anyone in that galaxy today looking around, they also see that they're at the center of their observable universe. You only need three statements to categorically conclude that we must be at the center of our observable universe: The age of the universe is finite. The speed of light is constant to all observers. Expansion does not differ between different parts of the universe. That's why "We're at the center of the universe we can observe" is just a different way to say "The universe has a beginning".

Can a photon travel forever and never interact with anything? Consider a Feynman diagram that shows a photon being emitted from an interaction on the left and absorbed in an interaction on the right. Time vector to the right, as usual. In the photon's frame of reference, travelling at the speed of light, there is no actual time. And at the speed of light, space is Lorenz contracted to zero. It seems that the left and right of the diagram are actually converged and space-time doesn't exist in the frame of refence of the photon. If all that is essentially true, it seems plausible that the photon cannot actually be emitted unless there is something that will eventually interact with (in our frame of reference).

Pigeon Crap. That microwave horn antenna (at 4:54) was built for Bell Labs as an experiment with satellite communications. My father was part of the team in NYC that was needed for calibration. It was well known that these horn antennae could be attenuated by bat guano and pigeon droppings. After extensive cleaning of the horn, the problem of noise continued and was later determined to be The Universe. Signal comparisons were made and it turns out that the static seen on TVs tuned to a channel without a carrier was caused by the same thing. So... When Carol-Ann looks away from the TV and says "They're Here" she might talking about Aliens instead of Poltergeist.

I found a pole in the CMB that was never discussed in any white paper, at least to my knowledge. The dipole moment was different than that of the galaxy, and so unless there was something very massive on the other side of our galaxy, this could only be the image of our sun's magnetic structure superimposed on the CMB images. Occam's Razer applies here, where the simplest explanation is the best. If a massive magnetic image in the stars is perfectly aligned with our sun's magnetic structure, they are the same thing.

One question I have that now has me interested further, is if we have determined that the doppler effect is something we have to correct for because of our movement through space, what about some other effect due to locomotion is a cause for the axis of evil? Is there a torque applied to an object as it moves through space? What angle is that at, and could that be a sort of hidden figure that could explain why the quadrupole seems to not match what was expected?

I predicted this "axis of evil" would show up if what we are measuring is in fact the heliopause, where the solar wind "stops" and radiates back microwaves. We are seeing the envelope around our own solar system. The multipole anomaly can be explained by the way the magnetic fields of the sun and planets disturb the outbound solar wind. The dipole is hotter on one side because it is closer. Similar to the way the magnetosphere is pushed closer to Earth on the sun side. The heliopause would be pushed closer to the solar system, in the direction of travel, from encountering particles in the interstellar medium. The "correct" way to measure the CMB, if it exists at all, is to measure it from out where Voyager 1 and 2 are. And even then it would be drowned out by the emissions from the Virgo supercluster. The heliopause is the boundary of the heliosphere, which is the spherical region around the Sun filled with solar magnetic fields and the outward-moving solar wind consisting of protons and electrons. It marks the theoretical boundary where the Sun's solar wind is stopped by the interstellar medium. The heliopause is located about 123 astronomical units (AU; 18 billion km [11 billion miles]) from the Sun. This boundary cannot be detected from Earth and must be identified from in situ measurements. The only spacecraft to cross the heliopause were Voyager 1 and 2, which reached it in 2012 and 2018, respectively.

I don't know enough about this to be any kind of an authority on the subject, but from the start of the video there was a discussion about the color shifting that occurs from moving frames of reference. Three frames were mentioned, the Milky Way traveling around the universe, the Solar system moving around the Milky Way, and the Earth moving around the Sun. There were also 3 poles displaying some sort of alignment. It feels like the Galactic motion is affecting the Dipole, the Solar motion is affecting the Quadrupole, and the Earth's motion is affecting the Octopole. The data was admittedly edited to correct for color shift, whose to say those corrections weren't off, or based on assumptions from a pre-'polar' model?

Mathematician with a technical question: exactly how similar are the axes for the 4-pole and 8-pole? Is it that no distinction can be found with our most precise measurements, or are they off by a small fraction of a degree? Same question for the perpendicular angle with the dipole, is it exactly 90 degrees or a small fraction off? Since you can create an infinite sequence of poles by subdivision, math tells us there will be a convergent subsequence, meaning that random chance would always lead to patterns we can pick out if we look long enough. How do we know this isn’t the case here?
@mathemagician26

Wikipedia says they’re actually off by “a few degrees”. If they can be off by anything from 0 to 180 in a uniform distribution, then this would not be too unlikely. To quote part of the article: “…their statistical significance is unclear. For example, a study that includes the Planck mission results shows how masking techniques could introduce errors that when taken into account can render several anomalies, including the axis of evil, not statistically significant. A 2016 study compared isotropic and anisotropic cosmological models against WMAP and Planck data and found no evidence for anisotropy.”
