Astronomy - Ch. 29: Galaxies (6 of 14) Barred Spiral Galaxies

To donate:

We will learn about 2/3 of all spiral galaxies are barred spirals, the Milky Way, and over time (billions of years) spiral galaxies become barred spiral galaxies.

Michel, do you know everything there is to know? 🙂 I am amazed at your breadth and depth of knowledge and understanding of so many subjects.

Was reading a book and came across the word 'barred spiral galaxy' glad I searched for this video coz this just increased my understandings of universe to a much higher level

[ImranKhan-dkjt]

Cool video just wondering what is your favourite subject since you know a variety of them

Barred sprial galaxies good night, it's 9:06 pm here.
Good Night Teacher and sweet dreams 😊

I also expect future studies to reveal States of globular clusters that may experience a barycenter type spherical mesh that can lock solar masses in place and prevent core collapse, yet allow expansion of clusters total mass, reducing formation of smbhs yet maintaining intermediate bhs. Think of asteroid belts and ort clouds as types of barycenter meshes. Imho

Sir
I was having doubt regarding centripetal and centrifugal force .
Sir When we are sitting in a car while taking circular turn we only experience centrifugal force .
We actually don't experience centripetal force at all.
I only used to mug up this concept without clarifying this doubt.
I ll be obliged if u may ans my question.
Regards.

Thank you for not saying milkdromeda and force me to go on another crusade to find the one responsible

I disagree with some of this. My expectations are that barred spirals are a state when a galaxy has a three body state of smbh clusters of Mass with elongated lagrange points and heavy globular clusters migrating toward and or suspended in the bar. Much like Jupiter and it's Trojans. And I would expect the barred spirals to evolve into spiral galaxies. Eventually time and studies will prove out this much like the current understanding of smbhs and clusters seeding the formation of galaxies that is now our defacto premise.

I can see my house!! Lol jk but love ya Dr! Your videos have definitely helped me with the physics portion of my MCAT!

wow I did not know that we lived in this universe full of wonders 😉🧐👍😉🧠
