An Unwelcome Place for New Stars (artist concept)

Description:

This artist’s concept depicts a supermassive black hole at the center of a galaxy. NASA’s Galaxy Evolution Explorer found evidence that black holes — once they grow to a critical size — stifle the formation of new stars in elliptical galaxies. Black holes are thought to do this by heating up and blasting away the gas that fuels star formation.The blue color here represents radiation pouring out from material very close to the black hole. The grayish structure surrounding the black hole, called a torus, is made up of gas and dust. Beyond the torus, only the old red-colored stars that make up the galaxy can be seen. There are no new stars in the galaxy.

Hi guys,
So far, I love this site. Great stuff. But I have some questions about black holes. First of all, has anyone ever ventured through a black hole? I thought a black hole was a rip in space, or something like that. Second, what do scientists think is on the other side of them? Thats about it. But this site is great. Ive always loved things about space ever since science class. I hope I hear from you guys soon. Thanx!

No one could go through a black hole because before they even entered it they would be ripped apart, a black hole would destroy any materials that we know of that is why they are so interesting and mysterious.
No one knows what is on the other side of them, there are quite a few interesting theories but thats all there is, theories.
Try going on to astronomy magazine site, they did a story on blackholes a few months ago, i think it was in the summer months but i cant remeber exactly.
