Thank u sir

very nicely explained. I finally understood what parsec actually means.

Thats soo good🎉

Okay. That explained the what very well. Now, what about the why? Why use such a convoluted measurement for anything? Why not just use lightyears?

Very helpful

Mc

can i have a question where does the 10^16 come from im confuse

YEARS OF DOUBT RESOLVED🔥🔥🔥🎉✨✨ THANKS👍✨💕

Does the same plane rule apply for the refraction as well?

I leave this comment because, u think this video is very helpful for me..😊

Very bad

Dude thanks a lot it helped me a lot

Good explanation 😊

Thank you for this information 👍

Great explanation 😊

Thanks a lot. ❤

Wow, what an explanation. I found this masterpiece after 1 yrs . Your channel deserves more subscribers ❤

it was helpful, thanks

Thank you very much.

Finally understood what it is! Your video was the best explanation! Thank you

Amazing thankyou

Excellent explanation.. clear and to the point 👍🏻

What is arc- second please clarify

Hi

❤

How to measure the angle?

The best explanation of parsecs yet .

So, to culcate the weber, so you use high volt to cause the impact to the magnet to see how much weber, it can absorb, so use that material since that materials will absorbs high weber, per high resistance to be used as storage to be use, so becomea battery. So, Iron is high captance, so good battery. You put motion of electricity which there is resistance or it goes around, Well, there is connect of circuit wire, which the electricity go around, so as it nears the magnet field in slow or fast, the motion of emf is faster. The point how weber is calculate. So, know what materials can be use as range of reluctance to permeability. The higher magnet force which the iron has so the absorbility rate, per second is high like weber show, so it is high weber mass, so the high part for weber is not base on how much, but how fast it can absorb. Tesla is for strengh, Weber is for speed.

I'm a genius now, thank you.

really nice and clear explanation thank you

What if star is on a line sun - earth then angle is always zero no matter how far is it. Useless defintion. Can someone explain ????

I prefer pc over lightyears

Helpfull

I really love your videos, Just keep on working day, I really appreciate your efforts. Lots of love from Bihar❤❤❤❤❤😊😊😊😊😊

i loved it😀😀

🎉🎉🎉

1 au = 1.496 * 10⁸ km not 10⁹

Thanks for this. I needed that graphical example. The internet failed me until you showed up.

I d browsed 10 videos. Everybody gave the value. Which I can get by Google. But nobody said exactly what it is

Next movie for Harrison Ford: Indiana Jones and the Arc Second of the Covenant.

Very well explained!! The animations helped incredibly with visualisation and understanding. Thank you.

I first saw this video but skipped thinking it wont be worth watching but later I came back after watching a lots of confusing videos....this is literally the best explanation about parsec....thank you soooo much for this explanation 😊

thanks❤❤❤

Great explanation 👍

Here is an explanation of why we use such a complicated length: Firstly we must ask ourself how we measure distances: When building small structures we just take a measuring tape and measure the distance in metres (feet, when you live in a stupid country). But when we build bigger constructions we use laser measurers. They beam a laser to the end, there it reflects and then we measure the time it needed for both ways and multiply that by the speed of light. But when we measure stars, we can not emit a laser and wait for it to come back. For distances of stars in our galaxy, the light literally takes years to come back (light years). But for these distances we triangulate the distance using the parallax-method. When we circle around the sun over half a year (opposide sides of the sun) we see that the star has moved compared to its backround. We assume that over the 6 months the background hasn’t moved that much and that the thing we measure hasn’t moved that much either, also effects like the expansion of the universe are so small, that we can ignore them. We can see that we can ignore all of this, when we measure 6 months later at the same point where we started. Over half a year we travel 2 astronomical units (180 degrees around the sun, so two radii/diameter of our orbit, which are called the astronomical units (with a rounding error)) We can measure the angle of the paralaxe shifting and by calculating that with the astronomical unit we can use trigonometry to give us megaparsecs I hope I explained that somehow understandable, English is not my mother tongue, I am German btw 🇩🇪

Going into grade 10 soon. Thanks for the explanation!!

Thanks so much for this explanation! Although I haven't learned about trigonometry yet, most of the video makes perfect sense to how it's measured.

Thankyouu❤

best explanation of a parsec i've found, thank you.

This is actually a really good explanation, but the voice almost drove me away. Plus I haven't learnt about trigonometry yet.
