Read the excerpt from neil degrasse tyson’s “death by black hole.” black holes are regions of space where the gravity is so high that the fabric of space and time has curved back on itself, taking the exit doors with it. another way to look at the dilemma: the speed required to escape a black hole is > the speed of light itself. . light travels at exactly 299,792,458 meters per second in a vacuum and is the fastest stuff in the universe. if light cannot escape, then neither can you, which is why, of course, we call these things black holes. which of the following features would best enhance the reader’s understanding of this excerpt?
a photograph of a black hole
a demonstration of the speed of light
an interactive animation of a black hole
a definition of the term black hole

Ok i am attempting to my niece attach a galvanized wire (like a tether for a dog) at the corner of two fences, making a tightwire if you will and we drilled a hole in a softball and she hits it. the ? and problem is that we can not get the wire taunt enough where it doesnt sag after hitting the ball once, and the wire sags and wobbbles. its a 15 ft rubber covered galvanized wire and one can adjust the length of the placing of the wire by having it make the corner of 2 fences become a it can be adjusted, however, with all our human strength and pliers we could not make it taunt as possible. is there anything other that attaching it to a car to do this. sorry abt the length but it would mean the world to my niece if i could solve this came up with the entire idea herself, and she is 14 and paid for the wire and did as much work as i did drilling a hole through a softball wide enough for attaching piece at each end of the wire that clips on to the fence. . any ideas welcome if serious. but awesome if it is a fact. much obliged. bucky bukowski buckman
