Firstly, please excuse my elementary knowledge and lack of eloquence when writing about astrophysics. I am a dentist, who occasionally thinks about the how the universe works. I'm both fascinated and frustrated with all of the questions that arise after learning more.
I was just watching a video showing the elliptical orbits of stars near the super massive black hole at our galactic center. Of course, as they turn around the black hole, they are then flung back out with tremendous speed. An animation of a large gas cloud approaching the black hole showed how the gas would swirl about after some entered the hole and some was flung out into space, thus illustrating how the massive change in acceleration effects matter with less mass than the entirety of a star.
I was wondering how this would translate to forces as we know them on Earth. For instance, what would happen (hypothetically) to a human standing on the surface of a star as it is violently tossed in its orbit around the black hole. Of course, I understand that the mass and gravity of the stars are many times greater than the Earth's, the stars do not spin like the Earth and it is not possible to stand on the surface of a star, etc, etc. (Please grant me a TON of assumptions here.) I still wondered, however, what would the forces "feel like" to an object of my mass (80kg) that was sitting on the surface of the star either on the near or far side relative to the black hole throughout the orbit? What would happen if Earth was subjected to these types of forces and changes in acceleration? Does inertia of a star orbiting like this even work like it does on Earth? Does the black hole "suck in" matter of lower mass on a star even if it's outside the event horizon, or would the combined gravity of the star and the "g-force" of the quick turn alone smash everything down on one side and toss everything outward on the other side? What happens with centrifugal forces with these sudden changes in rotation?
I know that is a lot to ask and to explain, but it would be greatly appreciated if anyone can shed some light.
