- Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales. Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe.
In this video, we have discussed about these two mysteries of the universe.

Thank you all for your love and support! - Фільми й анімація
Simple and very well explained ❤
Glad you liked it ❤️
I guarantee you one day this channel is going to blow up 💥
This is so beautiful and also interesting, this Chanel is definitely in my top 3 favourites
Hey bro I have a suggestion for you...
If possible do make a video on Quantum mechanics... Mainly time travel.. , it would be great if you do so..
This is one of the most beautiful channel ever! You even helped me with my studies! In than Horizontal velocity video...
Dang I love the way you deliver the information!
Namaste bhaiya its really a great channel and all the very best ❤
Marvelous voice and great visual
I wish you all the best for your channel, mate.
Thank you so much mate ❤️
Love your videos
Thank you so much ❤️
Nice explanation Buddy 👏 👀
There is a problem with the Hubble law. It has never been shown to be a constant. Therefore the HC cannot be used as a ruler to measure the distance of bodies based on redshift.
Hubble measured 4 galaxies. Two galaxies A & B were located around 16 megaparsecs away and the other two C & D were around 95 megaparsecs away. Galaxy A was receding away from us at 6,500 km/s while galaxy B was receding away at 500 km/s. Galaxy C was receding away at 10,500 km/s while galaxy D was receding away at 3,600 km/s.
If we determined the expansion of space between each galaxy none match the predictions made by the Hubble law (average) which is around 73/km/s per megaparsec.
Galaxy A = 16 megaparsecs away at 6,500 km/s = 406.25 km/s per megaparsec.
Galaxy B = 16 megaparsecs away at 500 km/s = 31.25 km/s per megaparsec.
Galaxy C = 95 megaparsecs away at 10,500 km/s = 110.53 km/s per megaparsec.
Galaxy D = 95 megaparsecs away at 3,600 km/s = 37.89 km/s per megaparsec.
The Hubble constant is not constant at all. Therefore it CANNOT be considered a LAW if none of these galaxies closely match predictions.
To top it all off galaxy A is 79 megaparsecs closer to us than galaxy D but is receding away from us faster. This does not indicate the further a galaxy is from us the faster it recedes away. space doesn't appear to be expanding at a constant anywhere. Thus a single solution like dark energy or Hubble constant cannot explain why a nearby galaxy A is receding away from us faster than the extremely distant galaxies C and D.
A redshift of 13.27 does not indicate a galaxy is 13.5 billion light years away because the Hubble constant is not a constant, it's an average.
Dark matter is inferred because of the rapid rotation of stars in galaxy disks. Stars did not reach their velocity all at once. It took tens of billions of years for them to reach such speeds. the older the star is the more momentum they would have acquired at a rate of about 0.0000002007 in/s. This is an acceleration of about twice the width of a proton every second. Extremely slow but over a long period of time would increase drastically. It comes out to be an acceleration of about 1 mi/h (1.61 km/h) increase in velocity every 10,000 years.
Our solar system is said to be 4,500,000,000 years old and orbits around the central core of the galaxy at a whopping 536,000 mi/h. If we do the calculations, take the mass of the solar system and the mass of the Milky Way and then divide it by 26,000 light years our solar system should be orbiting the central mass at about 86,000 mi/h not 536,000 mi/h. So, there is a huge discrepancy, about 450,000 mi/h between predictions and the actual velocity we're traveling. But if we account for this as a slow acceleration that occurs over great lengths of time, a 1 mi/h (1.61 km/h) acceleration then the math works out perfectly. Our solar system is 4,500,000,000 years old divided by 10,000 = 450,000 mi/h. It perfectly explains this extra motion they've pinned on dark matter.
Our Milky Way galaxy is 13,700,000,000 year sold and according to measurements using the CMB as a standard of rest we're moving towards what's called The Great Attractor at a whopping 1,370,000 mi/h. Our galaxy should be moving relative to the CMB all around us. So we're moving about 1,370,000 mi/h way too fast. But again if we take this slow acceleration it too fits the observations. 13,700,000,000 years divided by 10,000 = 1,370,000 mi/h. That exactly what the CMB data indicates.
If dark matter was spread evenly throughout the universe then why would our solar system have the same slow acceleration as the Milky Way galaxy over their lifetimes? The Milky Way galaxy contains over a trillion time the mass as our solar system. This motion is not a common factor of mass but a common factor of time. Meaning mass is not missing nor is it causing this motion. General relativity and the laws of motion are saved. Problem solved. They are right about gravity but are wrong to assume it is mass and gravity causing the extra motion occurring to stars and satellite galaxies. something else occurring over time is causing the motion. There is not any mass missing in these equations. There is only missing time and this slow acceleration of 0.0000002007 in/s, which comes out to be a 1 mi/h (1.61 km/h) increase in velocity every 10,000 years. Also, if stars and satellite galaxies orbiting around the barycenter of mass in each galaxy produces this slow acceleration then they would never be able to escape the gravity of the galaxy. An acceleration of a few protons every second is not enough of a jolt to change the star or satellite galaxy's trajectory away from the mass in the galaxy they are bound to. So regardless of their accumulated speed they would never be able to reach an escape velocity from the galaxy's mass. Too simple, I know.
This is awesome
Thank you so much ❤️
Throwing a ball up with an escape velocity will make the ball escape the gravity.
Yeah.. it's 11 km/s
@@shrutikashinde1008 Depending upon the position of throwing the object , from surface of earth ~ 11.2 km/s
@@r.k.sworld8945 yeah👍
Bro please make bio video downloadable please 🥺🥺🥺
Jai shree raam
The throwing a stone into the air analogy doesn't work. The rock needs to be quantum and its needs to be thrown at the velocity of Einstein Constant, lol. If you're going to be a reciter then be a better reciter, lol.
It’s called an analogy for a reason, so you’ve basically contradicted yourself
