ELI5: Why does every website want permission to give me notifications?

Why does every pseudo-news website want to have notifications turned on and how do these work? Will I get a notification if my browser is closed? Will I get a notification if I'm on another website? And what the hell are they even trying to notify me of?

Chrome has a notification API, and other browsers may have adopted it also. The intent was to make web apps more like native apps. Chrome has a background process that runs even if you close the browser that will show notifications, so yes you will see these notifications if you're on a different website or if your browser is closed. The websites want to send you notifications because it's a way to get you back to their site. News sites will probably use it to notify you of new stories.

I believe you can disable this background process by going into Chrome's settings, expanding the Advanced settings (bottom of page), then going to the System section and turning off "Continue running background apps when Chrome is closed".
