Long before astronomers found evidence that black holes existed, these exotic objects have captured imaginations. In the 21st century, scientists not only have proof that black holes are real, they continue to make startling discoveries both about individual black holes examples and about their populations across the Universe.

  • i'm pretty sure my astronomy professor told us you'd die from the extreme heat or spaghettification caused by the extreme gravity of black holes.

  • sad thing is, light isnt the fastest thing on the universe anymore. scientists discovered a single atom from this one source (i could not remember) that reached a sensor before light when fired. look it up

  • @codezeeky in other words, you're a retard. kgotcha

  • @laziestslacker sorry to tell you but your professor doesnt know shit about black holes

  • Thanks to Major Tom and ground control. Job well done.

    When I was sitting in the Movie viewing 20001, I never figured

    I would see this happen for real. Brave people made this

    happen.Your Harvard Web is doing a better job than NASA

    bringing the understanding to the non-experts Jimj122345.

  • Except for black holes are real and terrorists are fake. If we knew more on the subject, we could maybe catch up with the past civilizations, in that, they obviously knew more about the stars than us.

  • stop for 1 min. ask yourself this, do we really need to know all this stuff? 1:37 we can never see a black hole itself and yet we know so much more than we know about terrorist. use your brain people, wouldn't it be better to use the telescope to spot the terrorist and take them out instead of studying something light yrs away for no apparent reason? If it dose happen we would be alive to see it, probly another 2000 yrs generation will be able to study it but not us.

  • A black can only stop feeding if it runs out of gas to do so or it gets flung out of the system by another black hole.

  • This is the first time of me hearing this, what are you talking about? I am a physics major working with astrophysics researchers, and this is the first time I have ever heard that a black hole can even 'stop feeding', or even stop and start up again. Can you explain? (I am not being argumentative or demeaning, this just comes as a shock, and would like to know more).
