How Fast Is It - Chapter 7 - Black Holes (4K)

In this segment of the “How Fast Is It” video book, we cover Black Holes: what they are; how they’re categorized; how they form; and how they grow via accretion disks with jets that appear to accelerate matter to velocities faster than the speed of light. We cover the Kerr Metric for rotating energy densities that produce frame-dragging. We cover the anatomy of a black hole and the first image of a black hole ever taken. We cover how black holes are detected - including binary star system dynamics like Cygnus; galaxy center dynamics like our own Milky Way with Sagittarius a Star; by spotting disappearing stars; and with gravitational microlensing. We’ll close with a look at the two oldest black holes discovered by the James Webb Space Telescope (CEERS 1019 and UHZ1) and their implications for the Big Bang timeline and two alternative black hole formation theories (Direct Collapse and Primordial).

Hands down one of the greatest channels for all things astronomy. The voice, the tempo and the music makes the content therapeutic!

[Blackbird]

The Ideal channel for me-so tired of the snazzy cgi, I just want to learn and am thrilled that I still have this hunger at the age of 65!
Thank you so much for all of your fine work, it really is appreciated!

Dear David, your shows are an antidote to the soulless, CGI infested detritus so common these days. You feed us wholesome, nutritious food, not cheaply made poison. Thank you!

[placidpaddler]

These videos are unmatched. Love every minute!

Thank you Mr. Butler for the well put video. Happy New Year and may you continue to shower us with your intellect and knowledge. I know the past year was tough, but may you continue to recover and keep looking forward. We definitely missed you and your videos.

[gravelpit]

Thank you. Don't ever take down this content. You can scarcely imagine how many minds you're helping.

[JustinLCooper]

Thank you for the years of well constructed, informative, and entertaining content! It is nice to see the associated equations displayed next to the stellar imagery :)

[omarnassery]

Excellently narrated, with fidelity to science and respect for the intelligence and understanding of viewers. One of the best of what there is on Youtube for the general audience. Kudos, and keep it coming!

[ThePresentFuture]

I feel fortunate I discovered this channel.
Awesome, informative, fascinating.

Glad to see this episode come together. Many thanks

[jimcarpenter]

The content quality and production value are just incredible. So well done!

[mtrxQuarks]

Thank you, David, for this episode about Black Holes. You described the entire issue related to them perfectly. You showed many of the physical processes that accompany them. I am very glad that you raised the hypothesis about the formation of primary BH from denser centers of matter. That's how I imagine it. I watched it with great pleasure.

David Butler must be protected at all cost! Global treasure.

Awesome post! Happy New Years to all 2024!

This is the absolute BEST astrophysics channel on YouTube. No one explains the universe in such an intelligent, thorough, yet simple way. Perfect visuals, everything is just perfect. The necessary time is taken so that the viewer can truly understand the topic being explained. No one else on YouTube even comes close, and I’ve watched a LOT of physics videos, ha. Cannot rate this channel highly enough, just truly LOVE Mr. Butler’s videos. So good. Thank you! Please keep making these!

[fijiwizard]

We love you Mr. Butler❤ thank you for all you do & hope we get to watch much more of your beautiful work & many more years to enjoy it together :)

[sku]

I’ve watched this guy many times and it’s always refreshing to come back to him. Enjoy it thoroughly.

[rouser_bro]

Yours is the most informative and accurate channel on YT, far far away any other.. As always, thank you mr Butler

[Incognito-vcwj]

Nice, calm, mature, intelligent video without yelling and crazy visuals. A blessing to the ears and eyes.

[srb]

One of the most comprehensive, accessible, accurate astrophysical discussions I've ever seen on YT!

Thank you for your outstanding content.
