    I saw a documentary recently on The History Channel that speculated about extrasolar planets and the type of life that may exist on them. I'm beginning to believe life on other planets could be very different from anything we can imagine.

    One thing I had never considered is that, even though there may be over 500 billion stars in our galaxy, most of those may be uninhabitable due to the extreme radiation they may receive as you get closer to the center of the galaxy. It could be that only the solar systems like ours, out in the suburbs of the galaxy, are safe for life. Even so, that would still leave a mind boggling amount of planets that could be habitable.

    That's interesting, I haven't heard of those holes in our galaxy before, I doubt dark matter would cause them though...It doesn't seem possible even a concentration of dark matter making these holes like a bullet hole through the plane of stars...It must be something else...

    What do you think @Thomas R. Morrison ?...

    Statistically there should be areas where multiple supernovas occur. That would be my guess - a series of supernova events in the same region over a period of time could make a hole and leave no observable signs.
