Dark Matter Explained: What Exactly is Dark Matter? | A Beginner’s Guide to Dark Matter

Dark matter is an invisible matter that occupies more than half of the space of the observable universe but cannot be detected directly as it doesn’t interact with electromagnetic radiation, like visible light and gamma rays. One of the greatest challenges that astral scientists and researchers face before they can fully understand the universe is so-called "dark matter." Originally called the ‘missing matter’, dark matter is the name given to particles that don’t absorb or emit light, making them impossible to detect through observing electromagnetic radiation.

Think of it this way—how do you see or observe something in your everyday life?
You are able to see things because visible light, a type of electromagnetic radiation, bounces off objects around you and then reaches your eyes. All celestial bodies interact with electromagnetic radiation, including visible light, radio waves, gamma rays, and the rest. More notably, they alter the way radiation travels around them, which is how we detect far-off galaxies hiding billions upon billions of miles away.
But dark matter cannot be observed this way, because it doesn’t interact with electromagnetic radiation. Check out this video to learn more about dark matter, how was it first discovered and how is it detected now.

Dark matter is an interesting astronomical topic. I've gone through much information. Good that I too got more information about this in Science ABC too😀

[overpricedhealthcare]

1:00 why did they use the family guy background

[rohankhuriwal]

One of the best scientific channel out on YouTube

[dvdv]

I love how you used the Family Guy living room and the cyanide and explosm figurines all mashed together. 😀👍👏👏

This is not my comment but my smart friends. Anyway he says dark energy is the repellent effect created by the essence of cold. Even a glass of ice tea can be seen to push the vapor away. So at absolute zero it is magnified and is pushing space apart and at same time pushing and holding galaxy together because they are surrounded by empty space at absolute zero and it's no magic invisible matter but from outside the galaxy cold is pushing and holding them together and also causing expansion at same time. The repellent effect of cold space is the answer. So look outside the box or galaxy not inside for the answer . What y'all think about this? His name Daryle btw

Such a diverse topic explained with such simplicity and ease . Thankyou Science ABC!
Einstein was right when he said "if you can't explain it simply you don't understand it well enough". Thanks again <3

[lindahibbs]

Your explanation is very easy to understand!
Thank you for posting great videos ‼️‼️💯💯♥️♥️

[nihaalmoktantamang]

Thanks for being so amazing! Always support you 🙏🙏❤️❤️👍👍

Terminologies cause to much confusion. 2 staps forward 3 steps back. Get the idea to grow with you from discussion with others of the same mindset.
Basic schooling you say discuss but we don't our minds weren't ready but they are now with our new method x

[Eshakochhar]

It has been explained very well! Thank you.

Combine:
1. cosmological constant in Dx = lp^2/λ = lp^2 n. Then n = ( 10^-52 / 10^ 70) = 10^18
2. schrodinger solution
3. Planck E= h f= h n
4. n = number of superpositions per m^2

And you get dark matter = WIMP

n^2 h^2 / ( 8 m L^2) = h n
m = 0.3313 10^18 10^-34 = 0.3313 10^-16 kg ( all superpositions).

1 particle = 0.331 10^-16 / ( 0.4 10^18) = 0.828 10^-34 kg = 46 eV

If you count only the positive wave function amplitudes: n = 10^9
then dark matter = WIMP
m = 46 GeV

Hmm, we know dark matter exists because it affects ordinary matter. Interesting video by the way.

I have a hypothesis, gravitons are renresponsible for the energy possesed by planets , gravitons can also be held responsible for the formation of blackhole you can say it as holes in space time, which mainly compromises of empty space with no gravitons or less gravitons, according to one of the principle suggested by me universe tends to reach a state of equilibrium, as a result large rush of gravitons gets to the empty space creating strong gravity, thus black hole

[StephenJones-uver]

He also says that this explains both dark energy and matter and its not even missing matter but an effect of cold thats causing both. Does anyone have something to contribute to this?

[YossiSirote]

I think you should have stressed more that dark matter is by far from being confirmed. It is only speculation at this time based upon the lack of explanation of the phenomenon you described. There are alternatives hypotheses though.

[saitamabhaiya]

I'm waiting for the videos on fictional advanced technologies like the Cosmic Treadmill, Infinity Stones Mother Boxes, Nidavellir and lot more.. 😬

[jamesruscheinski]

for detecting dark matter, might there be a way to block light and other electromagnetic waves to try to measure dark matter?

[megatronsdragstor]

Another great hit . What a wonderful description of the dark matter .Some say that dark matter in our universe is less that why life originated here
Another multiverse have lots of dark matter larger than us 😎🧐

[Regularsshorts]

Dark matter interates with gravity, right?
What's the mass of a dark matter particle.

At about the 3:16 mark, it's stated that the velocity of stars near the center of a galaxy is the same as those at the edge of the galaxy. That's not true. The ones at the galaxy's edge are traveling much faster (relative to the galaxy center) than the inner ones.
