I have a background in CFD (computational fluid dynamics) and when I see these patterns, I immediately think of the surface of a slow moving river where these patterns are the effect of undercurrents. When I see rotation curves of most spiral galaxies, I immediately think of micro eddies also as a consequence of a flow field with a Reynolds’s number of 4000 or so. If you look at DNS (direct numerical simulations) where the flow field is resolved to the theoretically smallest eddy scales, this is exactly the same pattern that you see. Dark energy fits well in a great river model as well where you get non uniform accelerating expansion due to a dynamic free surface. The only thing left to accommodate is the Big Bang, the supposed beginning of everything. But what if it’s not the beginning of everything but only the beginning of what we can see? A big splash in this great river would fit nicely because it would result in the the highly energetic yet super low entropy signature as seen in the CMB. Maybe we could collaborate on a KZread video, Arvin.

Top notch presentation,. As someone who has been in the sciences for decades, I appreciate the quality of information. Clear presentation is not to be confused with dumbing down.it’s refreshing to have this type of quality. One caveat: ‘Might’ not impact us. This assumes that these speeds are constant.

How can we understand our galaxies movement towards great attractor. I mean movements are the key right.. i dont undertand . Please if you can reply please help.

Since the current speed of the expansion of the universe is greater than the speed at which the Milky Way is moving towards the great attractor, I think that means from an outside perspective, we speeding away from the great attractor and towards nothing but empty new space. Or I guess we are speeding towards great attractor but great attractor relative to our position is speeding away from us faster than we could ever hope to catch up.

The force of 'gravity' is not going to be of help since the weak vacuum of your lungs on the earth surface can already make you drink with a straw, so forget about a weaker gravity doing anything against the 'pull' of a enormous supposed space vacuum. This is a contradiction, so a 'space vacuum' cannot exist above our (existing) atmosphere. Problem with our education is that we trust our teachers and we don't have enough time to think about and test what we learn. Hence we get deceived...

The idea of a larger mass outside the visible universe, causing expansion (dark energy) is an intriguing idea!

Good stuff sir. Got a bunch of my required science fix here. Have a son who, when he was 15, declared himself to be the Great Attractor. He had just learnt about it in school. Ha, ha, funny son. Problem with that is the great attractor is way older than you and way more massive. Without missing a step, he walked up to me, patted my belly, called me Sir TGA, and ran out the door. I expected nothing less. Between ourselves, I was Sir TGA, and he was Mr. U. Every kiss begins with "K," but ugly starts with "U" son.

Thanks Arvin & The Team, you're all great.

Excellent video. Very interesting, informative and worthwhile video. Many thanks for the links to the papers.

My favorite theory involving dark flow is, There is another universe, outside of our own. At one point we thought that all the bright objects were suns/stars. Then we discovered that they included galaxies. Since then we have found Sagan Units of galaxies, you know, "billions and billions". So why can't there be a universe, out there, in fact Sagan units of universes, just beyond our ability to detect. More massive than our universe. Not strings or dimension, just more rocks on rocks, just like our universe with the same laws of nature. A lot more fun to consider, without all the elegant math getting in the way.

In classical rhetoric and logic, begging the question or assuming the conclusion (Latin: petitio principii) is an informal fallacy that occurs when an argument's premises assume the truth of the conclusion, instead of supporting it. For example, the statement "Green is the best color because it is the greenest of all colors" claims that the color green is the best because it is the greenest - which it presupposes is the best. It is a type of circular reasoning: an argument that requires that the desired conclusion be true. This often occurs in an indirect way such that the fallacy's presence is hidden, or at least not easily apparent. In modern vernacular usage, however, begging the question is often used to mean "raising the question" or "suggesting the question". Sometimes it is confused with "dodging the question", an attempt to avoid it, or perhaps more often begging the question means simply leaving the question unanswered. The phrase begging the question originated in the 16th century as a mistranslation of the Latin petitio principii, which in turn was a mistranslation of the Greek for "assuming the conclusion".

Not really. Are you and I moving farther apart? Is the moon moving farther from the earth? The earth from the sun? The answer is 'no'. The local effects of gravity maintain the distance between objects in their local gravitational field. You are not expanding outwards in all directions.

I really appreciate the way you end this. I am utterly fascinated with pretty much everything you covered (and explained so well!) yet at the same time I find myself terrified by it all. Like, I can't wrap my brain around the expansion of the Universe and Space-Time itself, because then I wonder why don't we observe this as each second of time goes on, if it's increasing at an ever faster rate? And when would it stop? Would it ever? Would matter itself expand? How far does this behavior of the cosmos go exactly? Just crazy stuff...

I learnt something new today. Very well presented! Of course, I do understand, our attempts to make more sense of our universe is mostly based on prevailing knowledge that we have accumulated so far. So, this may or may not be relevant in future when we are able to unravel the mystery of dark energy and likes of it, which perhaps we still aren't aware of, as yet. Nevertheless, learning something new is so exciting :) Keep them coming!!

Yet another video where Arvin knocks it out of the ballpark. Up until 12:40 I'd been getting fidgety wondering "how does this square with hubbles observed expansion?" I should have known Arvin wouldn't leave something as important as that unanswered. Thanks agian my friend, looking forward to your next video o7

I like you, Arvin! You didn't bore me or hit me with too much math for my BA/History to handle.

Very interesting and intelligible-the logical extrapolation would seem to be that all matter agglomerates to ever-denser units, until everything disappears into ultra-super-massive "black holes""-(which maybe then explode at "absolute maximum" temperature & pressure, restarting the whole cycle?)

Excellent video so well presented too 👌🏼

As you age, a day or a year is less of a percent of your total life than it was when you were young, so it kind of gets lost in the mix, as it were. It's how perception works, we don't see absolute differences, but proportions relative to the total.

I always found the memory explanation acceptable, how we only remember certain "critical" events and most of them happened when we were young and they all happened in a relatively short timeframe. The older we get the less memories get saved because the important ones are all already in the library and there is just not much new to add besides a few things like having kids and death of relatives/friends, so the time between those events is heavily shifted towards our youth and time simply goes by the older we get without much of it getting saved to memory. When you look back you remember the important ones and ask yourself where all the time has gone between them and now, because you cant recall much of it, but it happened.
