I actually feel so very short of words that are actually required for praising you as well as for all your efforts that you actually make every time in sharing your very knowledge with all of us.
ہماری یونیورس امیزنگ اور گرینڈ تو ہے ہی ، اور ہم اس کا بہت ہی چھوٹا سا حصہ لیکن ہمارے کام شاید گرینڈ نہیں ہیں انسانیت اور زمین کو لے کر کے 😔 شکریہ سر ہمیشہ کی طرح بہت انٹرسٹنگ اور امیزنگ کائناتی گپ شپ 🌌
We need you to make a video on only light! How is light, how is light made up of? Does light die? Light uses in the universe, does gravity affect light? Does light goes beyond the observable universe? What is the effect of black hole on light?
Thanks Hamza. Yes, we aim to have Kainaati Gup Shups every other week, and then Live Q/A and Kainaati Chai on other weeks. But these past two months were a little busy as we were launching Kainaat English - where the videos are different. Check out that channel too (there is a weekly video there) and please subscribe both channels: www.youtube.com/@kainaatastronomyinenglish
Ilyas - yes, we were working on getting the English channel ready as well. But now it should be regular - and you will get different English videos as a bonus at www.youtube.com/@kainaatastronomyinenglish (you can subscribe that one as well).

Very informative as always! Just listening to you and the puzzle about massive galaxies so early in the cosmological timelines popped an analogy in my mind. And that of the velocities of stars at the outer fringes of our galaxy. It was assumed rightly that their speed would have been less than those that are more closer to the center but observations found otherwise and hence gave us an evidence of additional gravitational force resulting from dark matter around the galaxy. If such massive galaxies really start to emerge as normal in early periods then an update of cosmology would be required. Any thoughts?
Thank you Asad - and yes, it is possible that cosmology may have to be revised. I think it is more likely that the interpretations of our observations will need to be modified. As I mentioned in the video, I think a modification of the distribution of stars may help explain the results. But this may be my own bias to galaxies and star formation... :)
Dear Salman Bhai, When the telescope look up into the sky how they actually identify the origin point from where all galaxies are originated. Indirectly, the point where big bang actually happened. It's so confusing, because when we travel in space it is quite hard to tell where is right, left up and down.. because it is all over the same...
See this video for some clarification: th-cam.com/video/DNj1MQnDBIA/w-d-xo.html. Big Bang did not happen in a particular direction. It happened everywhere - as all the matter we see today was once together (including my atoms and your atoms!!). So all the points in the universe today were once close together at the start of the universe... :)
Sir, I completed my four year degree in Mathematics. Further I want to study something related to space science for MS and PHD. Is it possible as my background is of Mathematics?
Hamid - no. It is a "time machine" in the sense that it can see galaxies that are so far away that their takes billions of years to get to us. So when we see them, it is as if we are seeing a galaxies from billions of years ago. But we cannot see our Earth, Sun or our own Milky Way in that way...
Sir please make a full video on ( [ HD - 140283 ] or Methuselah Star ) That's How Its age is older than our Universe age because that Star age is about 16 Billion Years, How? And We Know That According To CMBR, Our Universe It's About 13.8 Billion Years Old So How that Star is Older Than Our Universe. How can it possible?
Im done with astronomy science philosophy everything jo seekha kuch kisi kam nhi aya bs 7,8 saal TH-cam py reels ki jaga educational content dekha boht kuch sacrifice kiya pr keya faida
The names of galaxies are usually liked to some catalogues. Astronomers deal with hundreds of thousand of galaxies and so catalogue names along with their position in the sky (this is often the numbers come in). But then you have z-11 or z-13 associated with galaxies. This is to identify what astronomers call a "redshift" which designates how fast a galaxy is moving away from us and that in turn tells us about its distance. Z-13 would be farther away than Z-11. :)
There is a lot of overlap. But cosmology is the study of the early universe. Cosmologists are those who specifically study the early universe. Astrophysicists study stars, galaxies, and universe, and can also do theoretical work as well. Astronomers cover the entire spectrum as well, from planets, asteroids, and stars to galaxies and the universe, but often focusing on using telescopes, etc. I'm generalizing things here... but in reality astronomy and astrophysics can be used interchangeably.
Usman - well, it depends on what it means to "die". In some sense, one can argue that once galaxies stop forming new stars, they are dead...or that once ALL the stars are in the form of white dwarfs, neutron stars or blackholes...it is dead then. But you will still have those remnants along with gases that are not part of stars. Plus, 90% of the galaxy mass is in dark matter anyways, and we don't expect that to go anywhere... :)
بالکل سر آج تک کی سائنس کی معلومات کے مطابق تو آپ بالکل ٹھیک کہہ رہے ہیں لیکن سر آج کی سائنس ہمیں بتاتی ہے کہ اس کائنات کا آغاز ایک نقطے سے ہوا ہے مگر ایک ہی نقطہ ہر جگہ کیسے پھٹ سکتا ہے کیا ہو اگر کل ہمیں پتہ چلے کہ ایسا ہی ایک اور نقطہ ہمارے آس پاس ہی کہیں ہمارے نقطے سے بھی کئی کھرب سال پہلے پھٹ چکا تھا اور ہمارا نقطہ پھٹنے کے بعد اس میں مرج ہو رہا ہے اور ہم اس وقت ایک مرجڈ ورس میں رہ رہے ہیں؟اور کیا ہو کہ ہمیں پتہ چلے کہ جسے ہم ڈارک انرجی کہتے ہیں وہ ان دونوں نقطوں کی گریوٹی ہے جو ان ورسز کو نا صرف پھیلانے بلکہ پھیلنے کی رفتار کو بڑھانے کا کام کر رہی ہے؟ یہ سپیس جتنی واسٹ ہے اس طرح کے کئی نقطے مختلف جگہوں پر مختلف وقتوں میں بھی تو پھٹ سکتے ہیں آج بھی پھٹ رہے ہوں گے آئندہ بھی پھٹتے ہی رہیں گے تب ہی تو انفنٹی کا کانسپٹ صادق آئے گا نا۔معاف کیجئے گا سر میں نا تو کاسمولوجسٹ ہوں نا ہی آسٹروفزسٹ ایک عام آدمی ہوں پر سچتا ضرور ہوں اس لئے سوالات بھی ذھن میں اٹھتے ہیں ۔
Imran - unlikely - as there are many other things that point to 13.8 billion years. For example the Cosmic microwave background radiation puts a lot of constraints on the Big Bang... :)
ایک اور سوال پیدا ہوتا ہے کہ ایک کہکشاں بننے کے لئے ایک ارب سال لگتے ہیں ۔۔۔۔ پر یہ چھ کہکشائیں بگ بینگ کے چار سے آٹھ کروڑ سال بعد کیسے بن گئیں؟؟؟ یہی معمہ حل طلب ہے۔۔۔۔۔
Well...this is what the video is addressing. It is not that it takes a billion years for the galaxy to build. But rather, galaxies grow in size over time. So you can expect only smaller galaxies in the beginning. This is the puzzle. But it could be that we are assuming the mass wrong, or that early galaxies were a bit different than the latter ones.
You are right about that. Some of it has to do with history. In the 1950s, NASA was established as a public space agency as opposed to Soviet's more secretive program. So that legacy is still there...
Your constant hand movements and gestures are unnecessary and a very very big distraction and an irritation, please refrain and look into some speaking skills videos However the content and Delivery is very good
