Gravitational Constant: Explained!

What is the gravitational constant? Where does it come from? How important is it to Physics? Where is it used apart from The law of universal gravitation?

Why is this value this ?
We don't know

This made me smile

[cosmichappening]

Best and most truthful explanation I have heard: "We don't know". No ambiguity or BS of "Oh it maybe this, or it maybe that"...🤔

Anyone giving this video a thumbs down is an idiot. That was 6 minutes of great teaching. Well done. (I taught orbital mechanics for 4 years - getting that stuff across to students is NOT easy.) Again, terrific job communicating where our knowledge of constants like G comes from, and where our knowledge has its limits.

OH MY GOD I WAS ROLLING ON THE GROUND WHEN I SAW ENISHTINE HAIR IN 1:30

Omg that ending. I was hoping to find answers :D

Einstein said that if you cannot explain complex things in a simple way it means you dont understand it yourself. Could not agree more. You UNDERSTAND it. And I love your sense of humour! Great explanation! Thanks

[MathCuriousity]

What a delightfully clear and concise exploration!

[osubucks]

Thanks for the video. I've always struggled with this concept as an engineer, especially as it's used in U.S. standard units. It's nice to have some background as to where this magic number came from.

Make more physics videos! This is the most thorough, and yet concise explanation that I have found!

[nawtmyrealnamelol]

sooo we invented "G" just to make our equations work? Or was it always there? I'm not intelligent enough to grasp this

This is an absolutely outstanding video. Congratulations. Concise. Full of information. Entertaining. 5 stars.

You deserve more audience. Fantastic content!!

[George-O-mega]

Great! You know you've done a good job when someone with my background can say "oh, i get it"!

[melodyshow]

Only one doubt I have ..that What the hell this gravitational constant is😡😡😡

[natmc]

I was looking for something like this online - and there was nothing out there this compact and to the point. Thank you!

This is my #1, favorite science video on Youtube. Ab Fab!

[potatohugger]

Amazing explanation, I genuinely enjoyed your video! :)

[tobsmonster]

Thank you so much for this brilliant explanation. I spent years in school plugging G into equations without a care for how or why it was that value and now I know :). You've also given me something new to dig my teeth into - Planck Time! Thanks again.

Absolute banger of a video; this was very informative yet concise, and the visuals complemented the concepts well

1:05 Thanking you from India 🇮🇳 after watching this my doubt was cleared 😍🙏🏻
