What they are actually saying, is even the bit we thought we had a reasonable amount of knowledge we barely know. We thought the universe was made up of normal matter, the stuff on the periodic table... they now know at least 95% is dark matter and dark energy. The % is based on calculations that i don't understand. These are the best current models, that bare testing pending revision. It is vrry true that is the universe uf infinite there good be.massive variation... and scientists that are not sharing for the lay person would add layers of caveats and make clear but documentries tend not to add all those caveats... they would be too dry and boring for most to enjoy.

[@lewis7515]

Why would you assume that conclusion is an assumption? It's not an assumption, it's a calculation. We know the Universe is homogenous and what we can see, just doesn't add up - not by 1 or 2%: by 95%. We see that what we can observe behaves in a way it can only behave if 95% of it was actually totally invisible to us. You've totally misunderstood what's missing. Nobody is saying the totality of the region of the Universe we can observe is 5% of the Universe. W However, what people can calculate is that what we are able to see in the region of the Universe we can observe, can only possibly be, only 5% of what is actually in that region - we just cannot physically see the rest of what _must_ be there.

[@russellsmejkal304]

@@lewis7515what if we can see if we are jest looking at it all wrong. What if it’s not dark matter or dark energy what ever. What if it all has to do with magnetic fields everywhere even a extremely week magnetic field can attract things at a great distance and we only assume we know how strong a magnetic field really is because we gave it some random number wen we invented the word magnetic field and used a random machine that gave off a random number based of the strength of the magnetic field but the original amount was not it’s true value because like i said humans invented the amount randomly and called it zero to infinity ♾️. Not realizing. That they were wrong about it the hole time. And if they changed the base valve of it they will come out with a completely different valve in the end but it would still be right. Jest because humans invented the number that it was originally given. Sorry went of a way word rant there. But think about this if you’re in space you are constantly being pulled to earth right that’s gravity now you’re spinning around it that’s centripetal force throwing you away at the same time now take away all the planets in the solar system and come to a complete stop some how you will start falling towards the next biggest thing around. You will jest think you are floating around but you’re not and gravity is moving everything towards everything that gravity is the magnetic field that’s why you would weigh more on earth then you would on another planet like mars it has a week magnetic attraction. You can really explore this on earth itself there’s plenty of places ware the magnetic fields are weekend and you will weigh slightly less than you would in a strong magnetic field spot. This experiment has also been done so you should be able to look it up. But that 95% of what is missing it’s never been there it’s jest magnetic fields pulling on everything that’s also how they know some galaxies are pushing away from each other and some to each another even the galaxies have a north and south facing polarity. Anyway sorry this might make some sense or none at all but open up to it being possible

It quickly piles on the possibility of billions of humans with the capacity and capability to answer these questions and solve these problems having their lives utterly destroyed by brainwashing them into submission.

We don't just send out radio bursts, we send out highly organized bursts at varying frequencies and time periods and over a longer timeframes. One burst from a relatively secluded part of the universe is highly unlikely to be an alien civilization, in my opinion.

[@tracyavent-costanza346]

kind of ironic that one of the first "highly organized" radio bursts from earth, would have been the dramatic version of "War of the Worlds" (AM radio). Then among the first widely broadcasted TV signals would have been The Lucy Show. Lucy Arnaz of course, does get credit for having picked up the Star Trek franchise and syndicated it on DesiLu. That syndication popularized the now-common-idea of peacefully exploring space with a faster-than-light warp-engine technology and cooperating with alien species. And Gene Roddenberry's vision, as well as an interracial crew, left far reaching messages. Mostly to humans who in turn grew up to be astronomers and space scientists. And at the christening of the Space Shuttle "Enterprise" there was a formal event where NASA recognized the Star Trek cast and production staff for the influence they had upon generations of space research.

[@fekeetsa]

We have been doing so since the invention of radio. 100+light years is as far as we could have reached by now. And now billions of bursts occur at different frequencies daily. This will not help. Specific binary codes containing mathematical or chemical information is much more productive but has only been in use for approximately 35 light years. Not very far in a galaxy as large as ours. It will be many hundreds of years for a coherent message to be decoded and the the same to return.

[@tracyavent-costanza346]

@@fekeetsa and it does rather follow that some other civilization might have sent such messages long enough ago that today me might detect them. except they might have only been transmitting for a relative short time and we have only had the capability of receiving/decoding them for about 75 years. The lack of any (widely publicized anyway) is really not an evidence of not existing. Or to hesitantly quote william lane craig, "absence of evidence is not evidence of absence". For MORTAL sources that might be true, but if you are claiming your source to be omnisicent and eternal, that statement is much less compelling.

[@theRealist.]

What if we look at dark energy as a music? Imagine a "Harmonic Resonance Theory" where the fundamental laws of physics are expressed as musical harmonies. Each particle, force, and interaction corresponds to a unique note or chord. The way these harmonies combine and interact determines the behavior of the universe. Changes in energy levels and frequencies result in shifts in the cosmic melody, leading to new phenomena and transformations. Just as music creates emotion and movement, these harmonic interactions could shape the physical world in a harmonious dance of existence.

Could it be that when virtual particles pop into existence they pop the space they inhabit in with them, then when the virtual particles annihilate they leave the new space behind? Could someone do the maths and see if that explains dark energy?

[@tikaanipippin]

Virtual particles certainly increase mass, and when they get taken apart by black holes as Hawking Radiation, that increases both the mass of the black hole, and that of the space outside. We know that in our universe, there is an excess of matter over antimatter, so this seems to imply that supemassive black holes should have swallowed up an excess of antimatter over matter, so more matter is accumulating in the universe we live in. So the amount of matter is both infinite and increasing. There is little reason to believe a mechanism by which black holes select either the particle or the antiparticle in preference, unless there are unequal patches of positive and negative charges that attract sometimes positive or negative particles. It's hard to know what sort of magnetic fields a black hole could produce. There are more unpaired particles to collide and anihilate each other with subsequent release of energy, and these exist preferentially where there are no black holes to absorb them and that space is more rareified, for instance at the edges of galaxies.

[@jeffo4817]

I did. It don’t

There’s no need, even without any math I can tell you with absolute certainty that virtual particles have nothing whatsoever to do with dark energy. Primary reason being that, as their name implies, virtual particles AREN’T REAL!!😱

Another question: If the Heinsenberg uncertainty principle says that quantum states are uncertain until they're observed/quantified, how would the universe itself exist in any given state without an observer present for the whole universe?

[@robotaholic]

I think the universe is not expanding and speeding up. Instead, I think we are all shrinking because we're inside a black hole. A model of being inside a black hole really does fit our current observations. Maybe the reason we can see galaxies and stars way too old to fit our galaxy modeling is because of time dilation near a black hole. Forgive me for rambling and brainstorming. Neutron stars are my favorite objects in the universe 🤘🤩 and I have a lot to learn. Thank you for such an interesting video.

[@vanessacherche6393]

I’ve liked a similar idea since I learned a black hole with the mass of the observable universe has an event horizon with the diameter of said obvservable universe. I have wondered if our experience of seeing everything distant moving away could be the result of every point collapsing inward, dragging and stretching space time inwardly. It would be interesting if a shift in perspective could solve the dark matter and/or the dark energy mysteries.

[@vanessacherche6393]

What really happens inside a black hole? If no changes occur to an observer entering the horizon, could it be the same as what we experience being dragged toward the future? Approaching the singularity without ever making real progress towards it in space… acceleration in “expansion” of universe an artifact of “approaching” a singularity that is forever out of reach…

Everything that comes out of a Super Nova was there before the Super Nova, just now a gas with newly created heavier elements such as gold and iron. The universe is in entropy meaning getting colder converting energy into heavier elements not energy that burns easier. Heavy elements are still the same energy but colder. Those elements can now form planets and new smaller suns like ours.

[@johnmckee2671]

Thank you a very articulate program.

[@abdulhalim9650]

Wow ! These space mysteries are mind boggling and scary. Can we ever accused these scientists of over theorizing ? The recent lunar's mission to the south pole showed that we always got the unexpected, yet moon is our closest neighbour we thought we knew.

[@PublixJohn]

I love this stuff ❤

[@shaunjohnson1854]

I think we are constantly falling through space or the universe and moving around the giant mother stars in our galaxies

[@helicalactual]

I’m saying dark energy and dark matter are coming out of black holes or rather not black holes, but the accretion discs around black holes. They act like particle smashers as all the matter that’s grinding in, releasing more energy that current science predicts.

[@dreamwork69]

thank you for knowledge ❤

[@JimKrause1975]

Simply fascinating!!

[@red94mr28]

The Earth spinning faster segment (29:36) got me curious so I did a little research. The increase in Earth's rotation due to melting glaciers would depend on various factors, such as the rate of melting, the amount of ice lost, and the distribution of this mass across different regions of the Earth, such as the "equatorial bulge," that she pointed out. What wasn't mentioned is the time scale. It is estimated that if melting glaciers were to cause a noticeable increase in Earth's rotation, the increase would likely be tiny, possibly only a few milliseconds per century. It is very difficult to determine if such a small change in Earth's rotation would have any discernable impact on the climate.

[@AcamarWolf-Rayet]

Wow! never thought so many stars existed

[@flashflame4952]

That segment about the glaciers melting, etc was incredible and scary at the same time.

[@safeysmith6720]

Yes we are missing a huge piece, which explains our universe.

[@ophthojooeileyecirclehisha4917]

thank you so much

[@bill7576]

Our laws of Physics are still in its infancy! Give us a few more thousand years.

[@janakasanjaya6926]

Thank you

[@NeonVisual]

Perhaps it's like cell division. Space self replicates at the smallest scale.

[@AjaiTv.]

Eagerly waiting ❤❤❤

[@bsmith577]

The universe is actually shrinking and accelerating in its shrinkish.

[@healthdoc]

When an electron comes together with a proton to form a neutron does the electron simply flip one quark to a down quark? What is the relationship between the electron and the quark?

[@DarkKnight_]

the weak force is responsible for changing quarks

[@andrewbahr1921]

the genius of these scientist inspires and makes me feel as smart as a rock. but i lold at the "browning machinge gun sniper round" Some people are good at understanding the universe and the things around us, and others are ggod at taking it apart. bless these scientists and the work theyve done!!!!!!!!!!!

[@finalxgohan1]

It is a bit scary to think about infinite amount of space in the universe even living up to 1000 years old won't give you enough time to make it there. Space is huge, and somewhere out there I am going to assume there are different life forms.

[@desertdogstyle]

Great job on the video

следующий этап-второй этап-преобразования ВЕНЕРЫ-это погружение в водную среду-земноводных флоры и фауны, а главное водорослей, для выработки КИСЛОРОДА И АЗОТА И прочих ГАЗОВ, необходимых для развития атмосферы

[@WolfeBTV]

You said "...what hapoens when junk collides..." and now I've got a horrible parody of Powerman 5000 stuck in my head 😂

[@chrisbriden3833]

you think it, you see it, it's all taking place in the MIND It's all taking place on the inside and reflected to the outside. What seems to be the world is a reflection of our thoughts and beliefs in the mind.

[@uzayinsan]

AND YOU RESEARCH AND CHECK!!!

[@uzayinsan]

SORRY, I HAVE A LOT OF OTHER BUSINESS TO DO, TOO!!!

[@shannonspage9360]

It is just not knowing the medium that space exists in which will be difficult for us to detect due to our relative size by comparison. It would be like bacteria that lives in a whale trying to figure out the medium that makes up the ocean. Or if our planet was an electron and our sun was the nucleus of an atom and then trying to figure out medium that exists in between the atoms...atomic spacing and what it is made of.

[@morpheox]

Surely the Earth slowing down due to less of a gravitational influence from the evermore distant Moon must be a mistake? With a 28-ish day rotation around the Earth, the Moon is what is slowing Earth down, kind of like a dragging brake. Wouldn't the diminishing gravitational interaction between the two bodies lead to the decline in Earth spin actually slowing down, not speeding up? I.e. it would still slow down, but slower, not faster?

[@morpheox]

Also, I'm thinking the cold(er) water from the melting ice (from glaciers aswell as the polar ice caps) would not stay at the surface-as water is at its densest at 4°C-but sink, thus speeding rotation up even more.

[@jimgraham6722]

Thankyou, my suspicion is the missing super voids, anti matter, dark energy, dark matter will turn out to be various manifestations of the same thing.

[@afekasi79]

Woot!Woot! Dr Becky!!!

[@noahludford3667]

It honestly doesn't matter that the universe is expanding it only sets the timer on how far we can possibly reach.

[@user-zf4qv4mu3p]

This expansion is totally up for grabs now. Its not constant, its not uniform, not speeding up everywhere.

[@iatebambismom]

Good to see Dr. Becky on the Beeb. Wow!

[@noobskaterzrollupz3279]

Seriously interesting 😮

[@desertdogstyle]

You are a beautiful scientist

[@axzyzzen]

So there can be real heavyweight science and knowledge behind a clickbait headline😅 What a great entertaining science video👍

[@RaymondStyles-sx8bw]
