You’re out in space, far away from earth.  It’s 2316.  For days your spacecraft has been strangely moving toward something, but your sensors can’t determine the cause.  Then your spacecraft starts moving faster.  And faster.  Warning lights start flashing. The spacecraft starts to break up. “Black hole warning,” says the computer.  You go as fast as you can, but the gravity of the black hole is too much for the small engines of your spacecraft.  The spacecraft starts to be stretched, and so is your own body!  You have been “spaghettified” by a BLACK HOLE!!

I hope that got your attention.  At this website you will learn all about black holes (unless you close this tab right now, which would be foolish).  Now, go up to the top of this page and click on a link to another part of this website… but don’t get sucked into a black hole!
