A STAR HAS A LIFE. WHEN IT IS GOING TO DIE IT EXPLODES IN A NOVA. AFTER THIS OCCURS A COUPLE OF THINGS CAN HAPPEN DEPENDING ON THE SIZE OF THE STAR. IT CAN BECOME A WHITE DWARF WHICH WILL HAPPEN IF THE STAR IS SMALL. A WHITE DWARF IS ABOUT THE SIZE OF A MOON. IT CAN ALSO BECOME A NEUTRON STAR. A NEUTRON STAR IS WHERE THE ELECTRONS JOIN WITH THE PROTONS IN THE NUCLEUS, FORMING A RAPIDLY SPINNING STAR. THIS IS EXTREEMLY BRIGHT. OR THE STAR WILL BE SO BIG THAT WHEN IT EXPLODES THE MATTER WILL BE SUCKED BY SUCH A HUGE GRAVITATIONAL PULL THAT IT IS COMPRESSED INTO ALMOST NOTHING. IMAGINE SOMTHING SO DENSE THAT A TEASPOONFULL WOULD WEIGH SEVERAL TONS! IT IS HARD TO IMAGINE BUT EVEN HARDER TO EXPLAIN. THE GRAVITY IN A BLACK HOLE IS SO GREAT THAT EVEN LIGHT CAN'T ESCAPE. THAT MEANS THAT IF YOU WERE IN A SPACE SHIP TRAVELING TO ANOTHER PART OF OUR UNIVERSE AND GOT PULLED INTO ONE OF THESE HOLES YOU WOULD HAVE TO SOME HOW MAKE YOUR SPACESHIP GO FASTER THAN THE SPEED OF LIGHT TO GET OUT. BUT IF YOU WERE IN ONE YOU WOULD INSTANTANEOUSLY BE COMPRESSED INTO SOMETHING SMALLER THAN AN ATOM!
