Black holes and stars

  1. Jun 15, 2013 #1
    Hi,

    One can register waves of light.
    Is there anything known different then stars where we receive information from?
    Say black holes?

    I really guess.

    Hi bhpv,
    I think I can help you, but I really don't understand the question. Can you rephrase it? And be more specific?

    Yes, I agree w/ Dennis --- your question is incoherent

    Hi,
    Ok. Sorry for that.
    I do not understand what one can experience from black holes here on earth.

    Black holes are not directly detectable. We detect them by their effects on surrounding matter. For example, if you see a star orbiting around something, but you can't see the thing it is orbiting, then the thing is probably a black hole.

    First, I'd like to explain that I didn't understand that question because there are different answers to it but the general answer to that question is : yes!


    This question I understand :smile:. Black holes are very hard to detect, but there are good reasons for believing that they exist; as an example, astronomers have seen stars orbiting what appears as a very large "dark" mass centre in the centre of the Milky Way.

    I sincerely recommend this clip:

    Try a google search on "gravitational lensing black hole".
