Look at the below life cycle of a star. All stars BEGIN as a stellar nebula. 1.Do all stars turn into black holes? Explain: 2.Will our sun turn in to a black hole?
Black Holes How the Universe Works: Black Holes Video (Discovery Channel 2010) As we watch the video, you should be viewing with the intent of ANSWERING the questions (skim them now so you know what to look for) If you have questions, write them on your Graphic Organizer
The gravitational field strength near a giant star that collapses to become a black hole is the same before collapse (left) and after collapse (right).
It is only when you get CLOSE that gravity starts to change. If you get within a distance smaller than the original radius of the star, gravity starts to change. This edge is called the event horizon – once you cross it, nothing can escape…not even light! (so, we cant send any satellite signals out of a black hole) You will experience spaghettification – you will be ripped apart, and parts of you that are closer to the black hole will be stretched and ripped faster than parts of you farther from it!
