Iv'e heard it said that there are more stars in the universe than grains of sand on all the beaches on earth. I think there are more galaxies than grains of sand on all the beaches on earth. Our knowledge is expanding all the time who knows what has still to be discovered.
I’m just saying I want you to do something with that you can get a
I was watching one of these programs and they threw out that there are 3 trillion trees on the planet.
The amount of things we've discovered in only 100 years is astounding. Image the depths of information we will learn just 100 years from today, surely more groundbreaking things to come and I want to be around to see it
Totally agree, I 100% believe that more human effort should be placed into understanding space and it's inhabitants.
Keep the space content coming Spark. Great stuff. Thanks again!
agree. -rather than that millitary gloryfying docs…
Sparkling ✨️ as always !
Peace !
25:05 amazing that distant star systems seem to stay relatively in same distance from center and tend to bunch up then spread again as they revolve back to certain areas. Incredible
Every time I try to watch this I fall asleep 💤 😮
What a amazing channel!
Great work THank you
Sadly, the video is more about telescopes than blackholes. =(
Yeah, telescopes and exoplanets
If you leave the cap on the end of the telescope when you look through, it sort of looks like a black hole
@@TunaFreeDolphinMeat I like what you did there 😂😂😂😂😂
That is a proper documentary I'd want to pay for. Learn from this Magellan and Curiousity Stream !!
For some reason people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he 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 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."
We have all heard the phrase "mass becomes infinite at the speed of light" this phenomenon is illustrated in a common relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation (sometimes called gamma or y) on the vertical line. Mass that is dilated is smeared through spacetime relative to an outside observer.
General relativity does not predict singularities when you factor in dilation. Einstein is known to have repeatedly spoken about this. Nobody believed in singularities when he was alive for this reason.
Wherever you have an astronomical quantity of mass, dilation will occur because high mass means high momentum. There is no place in the universe where mass is more concentrated than at the center of a galaxy.
According to Einstein's math the mass at the center of our own galaxy must be dilated. In other words that mass is all around us because as the graph shows we are still connected to it.
This is the explanation for the abnormally high rotation rates of stars in spiral galaxies (the reason for the theory of dark matter). The missing mass is dilated mass.
SO MUCH MYSTERY
@17:36 "time stops at the event horizon" suggests that the distance to the surface of the black hole is infinite.
Basically we have no idea what we are looking at nor how much of it there is and we call an incredibly dense, impossible to escape Object "a black hole". But it is anything but a hole. It is impossibly dense.
@Josh Smith Baaaah!
It is truly fascinating what humans can accomplish in 100 years
I can confidently say that this is the best and the no.1 channel on TH-cam now, which has regular and quality content. If Spark had a TV channel, I’d love it!
You jest.
If I was you...I would search for the TH-cam channel KOSMO you'll change you're mind about spark
🏆🏆🏆👍🇺🇲🙏.
Thank you for sharing
The best way to "explain a Black Hole" to a Newb, would explain it as the Garbage Disposal of said Universe.
It takes in unwanted/unneeded material, but how it is "repurposed" is still in question...
The "Great Recycler Question" is how I see this Phenomenon!
How does a black hole know if something is needed or unneeded?
Might a better title be....telescopes, what we know so far?
what do black holes rotate ?
Very interesting and informative but the title is slightly misleading, still enjoyed it though.
I was about to say the same, i was looking for a similar comment and here it is.
This episode was okay, but they definitely hyped it up with the title, but yeah, still no waste of time or anything.
The universe is infinite, there is no doubt about it...
Goodeveng hey spark naic vedio.and is hostory its mai famili is and iam.thankyou
Black Hole is not a hole, rather a sphere instead. Anything with sufficient gravity will take on shape of sphere. Suns, planets, moons, and big asteroids are a 3D sphere, not 2D shape of hole like drain in a shower.
Jets of energy can not come out of a Black Hole. Nothing can escape including light, all forms of energy, objects, etc. Light has no mass, yet it is held tightly once it enter Black Hole. We can see the effects of a Black Hole, but we can't observe it directly. There is no wormhole connecting to another black hole.
There is no shiny accretion disk like the rings of Saturn, unless a single object is being pulled apart. There is a accretion layer on the outside of 3D Black Hole Sphere. Multiple objects surround it and are in multiple stages of destruction. The accretion debris would look like bright frosting on a black bowling ball.
You can see the frosting, but can't see what is underneath. Further, this only occurs when objects are being pulled apart by gravity. The accretion layer could appear in different bandwidths. After all matter has entered, only a Spherical Black Hole remains and that can't be seen directly.
We have no idea what's inside. Nothing: IR, UV, Visible, X-Ray, Radio wave, comes out. After the accretion layer vanishes inside, the Black Hole truly is 'black', it is the blackest thing in universe.
The 'photos' of black holes are computer generated using invisible wavelength data and converting into visible. Use of large radio telescopes, like any other imaging device has limitations. Scientists rush out the latest and greatest, but 99.999 percent are not even close. Most of it is pure speculation.
Distance versus resolution versus location versus noise versus. So they use 10 devices, get 10 times the resolution, but also 10 times the noise. Most of these objects are so far away, behind other closer objects. We capture a single pixel of data. The gears that drive telescope are pretty precise, but a 100th degree of local hot / cold can change accuracy by fractions of arc seconds. That is 1,000 times more than the size of captured data.
If black holes have infinate density, then why are there black holes with different diameters ? Shouldn't infinate material fit into a space the same size, with no limit? Matter must crush down to a finite size, then when nothing else fits, it's diameter grows. So maybe matter's smallest size is not infinite. Meaning its diameter is what has no limit.
The event horizon is the effect of the singularity at the core of every black hole, one could argue that the event horizon is not the actual black hole, when we see vortexi in nature, they are varying sizes, based on the strength of the force that causes them, the same can be said about the gravity the singularity has.
The sun produces energy which gives it a magnetic gravitational pull, so if one method to producr energy by photons and array of lights on our skin, so do we radiate energy and if we do where is that energy gravitating towards
I tried getting to sleep listening to this - but had to give up. It's riddled with adverts which go on and on and on.
It's about time TH-cam got it through their thick heads that the ads generate fuck all for the advertisers, they piss off the viewers but are there merely to justify the vast fees charged by TH-cam
The ads are the reason why I have a subscription to TH-cam. Then I can sleep.
Tell me once you've found an alien civilization with HD footage from one of the satellite's advance telescopes. I want to see alien civilizations!
👍
Are black holes orbiting anything?
This video is about telescopes. Very little black hole info
14:45 there are plans? 💀💀💀
we are all living in a big toilet someone has already flushed
James Webb telescope outclasses Hubble - its about 6.5 meters in extent.
6.5m in extent sounds like a fat american FTT!
When they all accumulate to a mega blackhole only thing left will be a big G?😅
Quasars are where it's at.
@Josh Smith They fascinate me to know end. Them, and their buddy The Neutron Star.
@Josh Smith So me suggesting SEA's video on Large Quasar Groups is moot? Darn!
Seen it perhaps a dozen times.
@Josh Smith Yep.

There's no end for space exploration, no matter how far we go still will never be enough!!
Beautiful how massive this universe is.
Woopie
This is definitely not current, one of the most frustrating things on the internet is all of the “misleading” titles!!
Blackholes are a portal where angels travels, someone said and i think it may be right.
Nah. Black holes are what Bigfoot used for vacation. Just as likely as likely as angel portals. 🤦🏻♂️
@@DisposableSupervillainHenchman Nah its the place your brain went, looks like it never made it through
@@MohamedEzekiel My brain just fine, thanks. I’m not the one spouting off nonsense about angels using black holes as portals. You sound like a mental patient.
We are in a black hole right now! Prove me wrong
Don't want to prove you right either we'd all be on a tight spot won't we ...The Black Hole of Infinity .......
that's not how science works!
you need to prove yourself right first!
personally I think we are in the very center of the smallest part of an atom.
If we was in a black hole...the stars we see in the night sky would not be where they are...instead they will be spinning around out of control
Has anyone been in a black hole???
Yes... Now I have few STDs....
What if our whole universe that we are living in right now is existing within a black hole in another dimension
@@lovingdeanthegodmachine5622 we ain't even been on the moon yet
@@rupruprup8690 Yes we have. July 1969. Read a book.
We know nothing about Black holes.
We barely know anything about our next door neighbor, Mars.... Let alone a black hole....
We know quite a bit about them, except for what happens inside.
Also, the answers to our key questions are found within the data succinctly referred to as the initial values culminating to the big bang.
TLDR: since it is highly unlikely (actually, "absurdly" so, to put it mildly, even flattering) to be from random processes then, logically, it is not and, therefore, by design-deliberate & intelligent design.
Furthermore, postulating multiverses is even more highly unlikely, since the unlikelihood is exponentially compounded to way beyond comprehension!
Just do the math!
Everything is illusion. There are no galaxies.
سبحان الله و بحمده و الله أكبر
@spark change the title...this isn't really about black holes...more about telescopes to exoplanets... Don't be fooled to those who want to watch this.
We are living within a black hole. Our whole universe IS the black hole. Within the endless universe of the eternal universe of the eternal God, the home of Jesus. This universe is not our home, the solar system is the home of all demons, it's the kingdom of chaos. Read the secret teachings of Jesus. First of all Secret book of John. It's all a lie we're living in. Human never sinned against God at the beginning, like the Bible says. We are all creatures of the darks, they wanted to imitate the true God and created the human according to the picture of the real God, because they wanted to be higher than the higher God. The whole world lives in a lie.
Just an old rerun. Nothing to see here.

What if… we are just a “cell” drifting in the depths of a massive ocean.
