I’m hotter than both of them
I have no doubt
Quite a few more particles...
There’s no theory of gravity. Relativity?
what do you mean? The modern theory of gravity is a theory of relativity, but it may not be correct if dark matter does not exist
I thought you quit running the channel
Do you believe there exists a parallel universe?
I have a video about this topic: kzread.info/dash/bejne/Z615srNygZq1mco.htmlsi=KbS5jszVKKAZ0lXV
@Aedviluen no I mean your personal opinion
I'm skeptical about this
Here is the explanation for galaxy rotation curves - General Relativity predicts dilation, not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light." He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is just one aspect of dilation, it's not just time that gets dilated. There is no singularity at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. More precisely, everywhere you point is equally valid. In other words that mass is all around us. Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. To date, 6 very low mass galaxies including NGC 1052-DF2 and DF4 have been confirmed to show no signs of dark matter. The concept of singularities is preventing clarity in astronomy. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Feynman etc
"Our universe is believed to be flat and infinite"???????? Nobody believes that the universe is irrelevant. In fact the universe is IMPOSSIBLE TO be infinite. Also when you hear the world "infinity, infinite and infinitely small, that doesn't mean LITERALLY infinite, but an arbitrary big number that is so big that is either too hard to pin point or too irrelevantly big to name it.
Yeah it's good stuff it'll be great to get some compilations so I can go to bed listening
Hope you can keep up with the good quality of this piece of fine KZread video. I am no. 252 of your „followers“ ;-)
Super underrated channel
I appreciate that!
beautifully explained, i’m going to have to subscribe and watch your other videos. <3 -a huge space nerd
Wow, thank you!
Is this still a text to voice? It’s quite convincing / natural.
You got the facts reversed at 1:30. You said Shapley claimed the nebulae were other galaxies while Curtis believed the Milky Way was the entire universe. It was the exact opposite; Shapley thought the Milky Way was the entire universe and Curtis said the nebulae were other galaxies.
ΚΑΤΑΠΛΗΚΤΙΚΟ ΤΕΚΜΗΡΙΟΝΟΝΤΑΙ ΤΑ ΣΧΕΔΙΑ ΜΟΥ ΜΠΡΑΒΟ
Amazing channel! I absolutely love what you're doing ❤❤❤❤
Thank you so much!
What was the question? Where I put my shoes ? Ya that’s it
Good video, with mistakes! at eight minutes you say the fastest spacecraft travels at 6 percent the speed of light. The fastest speed by a spacecraft is 163 km/s (586,800 km/h; 364,660 mph), by the Parker Solar Probe, 6 percent of the speed of light = 17,987 km/s! the Parker Solar Probe reached 163 Kilometres per second = 0.00054371 Speed of light. You then said that even at the speed of light it would take billions of years to reach neighboring galaxies. The Andromeda Galaxy is only 2.537 million light years from Earth. Keep up the good work, but check your facts, you are missing well known numbers by orders of magnitude.
Finally a good new channel , refreshing in this avalanche of clickbait nonsense science channels. Very well made , good voice and naration, good format as well. I wish from my heart you will grow fast ! Subbed so hard i split my mouse like a proton. Cheers !
Much appreciated!
Gotta be very impressed with Shapley. He argues that the Milky Way is the only galaxy in the universe. He is presented convincing evidence that he is wrong. And then instead of clinging to his previous position, he accepts the evidence and shifts his work and focus and catalogs 1,200 galaxies in six years. Beautifully done Mr. Shapley.
Absolutely - that‘s how we all should be, isn‘t it? With regards to this part of his work: an absolute role model!
Thank you so much for the detailed video! I have prepared a similar video in my mother language, and I am just wondering about 1:31 concerning the great debate, i guess it's the opposite where it was Curtis arguing that the universe is composed of many galaxies similar to our own, while Shapley believed that the spiral nebulae ( galaxies now) were mostly nearby gas clouds, and that the universe was composed of a single large galaxy, after Edwin Hubble's calculations he accepted the fact that he has mistaken and actually worked on globular clusters. Also in 4:26 you were saying that Shapley supported the idea that the milky way was our entire universe, which confusing comparing to the first part of the video. Thank you for clarifying in advance, and I appreciate your efforts and way of simplifying facts.😊
"How do we know the shape of the Milky Way if we are in it?" Strictly speaking, we don't.
This question has been bugging me for a long time. While this clip does not answer the question completely to my satisfaction, I now "get it" to a great extent on how this question can be answered. This is what science is all about isn't it; always fine-tuning our understanding based on observations, deployment of new methods and technology. Thanks for sharing. New sub.
In short, graphics aside, if you have ever looked at a monastic itinerary map or its more modern equivalent the London Underground map - well, that is what we now project upon our understanding of what we perceive around us. They are not myths and here-be-dragons legends they are actual maps aka 'mappa' i.e. napkins upon which we stylise a drawing on a plane surface of information that represents (or now records) a part or the whole of data spread across point, time and relative dimensions. Only some of what is - out there, in reality - is therefore presented .. or photographed = traced by light, etc; and yet enough to make a fairly good job of helping us to distinguish between, let us say, Cannon Street and Mornington Crescent (and why it might be necessary, or at least entertaining, to know the difference, even if one has no intention of finding out, even if one were able so to do). ;o)
I made a photo of a 60W bulb against a strong backlight
Nice...keep it up!
Thank you, I will
Thanks for sharing this ~
My pleasure!

So.. the core of the sun is yet hotter than the surface of the sun? Or... Is the core of the sun hotter than the core of the earth?
the core of the sun is much hotter than the surface of the sun and the core of the earth
Subscriber #99.. 😁😁 I'm not an astronomer so I have no idea if your info is correct.. but the visuals are great and the vocal presentation sounds professional. Good content!!👍👍
Awesome, thank you! I am a master's student in astrophysics and I retell on my channel simplified information that I studied at the university and in practice at the observatory. But I will be glad if someone corrects me, no one is perfect
We'll never know what is on the other side of the center of our own galaxy, but if the rest of space is any indication - just more of the same. Walking into any area of technical expertise is awe inspiring, until it becomes everyday and tedious. Knowing our limits in both understanding the universe and traversing it has put it on the shelf for the most part although many continue to chip away at the edges of known dogma. Perhaps this is what drives some of the desire for AI, so we can feed it everything we know and get back the number 42.
Fantastic video. Hope channel grows fast and we get more of this!
Thanks!
You Gọt mỹ vote💋
Damn bro.
I’m making this comment to tell you to keep it up with the voice over videos they’re great I absolutely do not like the text to speech voice lol your real voice is perfect, also there’s a typo in the title of your video on the expansion of the universe
@@ncs2104 lol there is no universe where this robot voice isn’t a text to speech voice, if I looked it up I could probably find the exact text to speech voice he used, real people speaking sound nothing like this
Ok thanks!
Thank you. I always wondered about this
Glad it was helpful!
I was just wondering this the other day. Seriously. LOL!
glad I answered your question ❤
Really good video man. ❤ keep going
Thank you
Only our lifetime sky that has stars to beat Satans , so the other Skies are protected?! Are Satans that bad ?! What do they do that we can't do !!
Allah = pig 🐖 🐷 🐽
Great video, this is really interesting to learn about and it must have taken a lot of effort to find out and research all of this and make the video, I wish you a lot of success in the future, this is really good content :)
Glad you enjoyed it! Thank you for your support, it means a lot for a small channel
cool
Thank you for your support, it means a lot for a small channel ❤️
its a black hole, infinite yet finite, if you can go faster than light you can break free, but seeing as nothing can we cant. Think about it like this, space twists at the point of a singularity, we have no real idea what happens to it, but the route to source gets closed off to ordinary matter, imagine standing one side of the grand canyon, the river is flooded completely and the river bends away from you, there is no amount of speed you can put into yourself so you can swim thru the waters, at the point in space around the black hole this is what it must be like for anything getting too close to the singularity, space twists so much even light gets twisted and refracted, there is no route to source, only another black hole can even come close, but then what happens, do they orbit eachother inside the event horizon forever? 2 unbending immovable forces, they wouldnt ever come together unless one loses mass or energy, but when they do oh boy, imagine what happens inside that bubble, if the radiation of the singularity is like a star it will be super heating itself, all the energy and radiation coming back on itself instead of being radiated away, and then there is the pressure and density, do you think it would be a hot or cold singularity? things would be so confined even the subatomic would be struggling to vibrate, yet there is so much confined mass and energy, wanting to be released. Is there another dimension of reality where black holes orbit around eachother in twisted parts of reality for near eternities without ever coming together? Lets collide 2 potential supermassive black holes together, i imagine when they come to the point of sharing energy its quite the event, the mass of 2 objects forced to become one when they don't like being what they are, its so much force and pressure that so much energy gets released, and hey if E=MC2 why cant it be space and time, with enough energy being released with nowhere to go the spacetime propagates into the limitless void we have to work with between the singularity and the event horizon, remember we cant travel faster than light, even that initial boom, happened everywhere at once, gravity for the singularity ceased to exist as a thing, trading off for spacetime, leaving energy to condense in its wake into the universe we see today, it allowed entropy to happen again, a new era of spacetime born from infinite gravity mass and density, if we could go fast enough now we could find a point in space where the initial light from the big bang hasnt happened, you could travel for infinity at light speed and never reach the event horizon, but you could witness the birth of it all if you could go a little faster and knew just when to stop, it might take you a few billion years to get there, but in that slither of reality, infinity in a limited space, there is a potential to expand until the universe decays, and the singularity we are inside will never get the information that we are dead, hell the universe we are in could be dead and we too wouldnt get the information, all because of these gravitational pinch points, like christmas cracker necks, they let things in if they are already outside of spacetime, but other than that you are just riding around the outside cardboard as part of the picture.
Good vedio bro keep it up
Thanks
Dark energy is bs.
in cosmology we cannot say anything 100%, but the modern cosmological model cannot do without dark energy
How it is possible, that vacuum can be energy?
Black holes are based on a mathematical misconception. General Relativity predicts dilation not singularities. In the 1939 journal "Annals of Mathematics" Einstein wrote - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star clusters) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light". He was referring to the phenomenon of dilation (sometimes called gamma or y) mass that is dilated is smeared through spacetime relative to an outside observer. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is one aspect of dilation. Wherever there is an astronomical quantity of mass, dilation will occur because high mass means high momentum. Dilation is the original and correct explanation for why we cannot see light from the galactic center. It can be shown mathematically that the mass at the center of our own galaxy must be dilated. In other words that mass is all around us. This is the explanation for the abnormally high rotation rates of stars in spiral galaxies, the "missing mass" is dilated mass. Einstein wrote about dilation occurring in "large clusters of stars" which is basically a very low mass galaxy. For a galaxy to have no/low dilation it must have very, very low mass. To date, 5 very, very low mass galaxies have been confirmed to show no signs of dark matter. For the same reason binary stars will always have predictable rotation rates. What we see in modern astronomy has been known since 1925. This is when the existence of galaxies was confirmed. It was clear that there should be an astronomical quantity of light emanating from our own galactic center. It wasn't until television and movies began to popularize singularities that the concept gradually became mainstream. There was clarity in astronomy before the concept of singularities took hold.
Your assumptions {not proven} are that the black hole starts at the Event Horizon proceeding inward to a singularity {not proven}, and then you provided an average density {of some unknown substance} based on those assumptions. There's no reason to assume you are correct.
Of course, we cannot experimentally confirm the structure of black holes, for obvious reasons. But our general theory of relativity has been experimentally confirmed and the partial solution to the Einstein equation for a black hole is the Schwarzschild Metric, from which it follows that the black hole is limited to the so-called event horizon with a Schwarzschild radius. We don't know how the mass is distributed inside the black hole, but we know the mass and volume of the black hole and therefore can calculate the average density.
@@Aedviluen Exactly, we humans, of limited knowledge, have arbitrarily assigned the beginning of the black hole as the event horizon, which is the equivalent of calculating the volume and density of the earth at the outer limit of our atmosphere. Further, the average density is an entirely meaningless calculation, in that it describes nothing useful in the real world/ universe. We could also calculate the average density of the Solar System, with equally meaningless results. And this would not change, even if we calculated it with the Sun being a singularity.
@@Aedviluen Of course, the Scwartzchild metric is the gravitational field outside a spherical mass, and as the event horizon is not a physical mass, we then go with the Schwartzchild radius, which is from the center of the black hole to the event horizon. Calculating an average density of a given mass and it's surrounding space is an entirely useless measurement for a couple of reasons, first the Schwartzchild calculations are based on, among other things, zero angular momentum, and black holes can have monstrous rotational rates. Also, calculating an average density is pointless because it produces no useful information (at some level, there must be a density gradient). An average density can't, for example, determine the size of the black hole mass. We could also calculate the average density of the Solar System to include the Oort and the Kuyper, but it would be just as useless. PS angular momentum is an entirely different discussion.

Um
6x more dense than air :/
Switzerland trying to be neautral😂😂
The temperature of the universe during the Planck era 🗿
The temperature in the Planck era is theoretical, the author spoke about the temperature that we recorded
@@Aaroncoppelmangood point
@denysliashev411 is right, I want also add that if we think about what the highest theoretical temperature is, then we will understand that there is no limit (at least in the modern physical model), for example, somewhere in the universe we can have a collision of several particles with sooooo much energy that the temperature has no limit, but we won't detect it
