    How Can We Be Sure About Black Holes and Galaxies?

    OK I'm back, went did some reading. Everything I'm reading I'm assuming is mostly theory. Understood. So if this is all theory, how can we be certain this is right? I'm not trying to make anyone mad by stating this, I'm just being curious. (I meen come on, once upon a time we thought the Earth...

    How Can We Be Sure About Black Holes and Galaxies?

    Sorry to confuse, had baby girl at same time. Totally thanks for the info Nabeshin, I'm reading it right now.

    How Can We Be Sure About Black Holes and Galaxies?

    AHHHHHHHHH, that makes sense. Got ya. I knew there was an answer some where's. OK, so let's back up a bit in time right as the sun starts to do all this. The sun goes through these phases where it loses it outer layers as in collapsing or exploding or what ever it does and the core is left...

    How Can We Be Sure About Black Holes and Galaxies?

    Yeah, have to think theoretically. But still, that's some pretty wicked stuff. So if it starts out roughly around 12 - 15 km, how does it get to the size of a head of a needle? Its already compressed beyond belief, but to compress more... I know its massive pressure, and its getting broken down...

    How Can We Be Sure About Black Holes and Galaxies?

    WOW, that would definitely part your hair! So when they say a teaspoon full of matter would weigh something like 40 billion tons, there serious. That is almost incomprehensible! But seriously cool.

    How Can We Be Sure About Black Holes and Galaxies?

    Thanks v2kkim. Your not deviating as far as I am concerned, it is the subject of both galaxies and BH. You guys are like walking encyclopaedias on this stuff and it just fascinates me beyond belief. I would like to thank everyone for trying to help me understand more of this and you have. I know...

    How Can We Be Sure About Black Holes and Galaxies?

    Hmmm, that makes sense. So like what "v2kkim" posted up above, when the galaxies do "collide", it will and does make new stars, I am assuming this would be from the gas and dust "colliding" (friction and gravity and more) as the two galaxies are merging or passing through one another? Which in...

    How Can We Be Sure About Black Holes and Galaxies?

    I did say that is far fetched. And who knows, why couldn't we be here. OK DaveC426913, you got me curious again! LOL You stated that "They gravitationally interact," can you explain that a little more. I'm guessing your trying to say because of the massive gravitation between all of these...

    How Can We Be Sure About Black Holes and Galaxies?

    WOW thanks for sharing that v2kkim, that is so cool. And one would think that if two galaxies collide, stars would collide. But they don't or almost never do no matter how catastrophic. That is really interesting. So if one is to think that if let's say Andromeda collides with our galaxy in a...

    How Can We Be Sure About Black Holes and Galaxies?

    Well, like I said. I know its more technical then what I stated. (on the other hand I don't need to know how many solar masses something has to be before it can do something else or a bunch of crazy math to have a simple understanding of it.) But I put it into terms I can understand. Remember...

    How Can We Be Sure About Black Holes and Galaxies?

    No DaveC426913, that's not what I think, Its just my ignorance in this field against your experience. This is how I learn and I have learned a lot thanks to all of you. And as far as photons rotating around the black hole that makes sense. Gees why don't I think that far ahead before I write...

    How Can We Be Sure About Black Holes and Galaxies?

    I'm sorry DaveC426913, mostly what I know is from what I read. And I fill in the gaps to make sense to myself. So this is mostly from my speculations because mostly what I read they leave gaps all over the place with no real explanation. Sorry, I should have said that. That's why some of my...

    How Can We Be Sure About Black Holes and Galaxies?

    That's interesting. I always believed that a black hole had more gravitational effect then that. So its really no more then obviously the collapsed layers and core of a sun that is exposed, then I'm assuming it slowly turns into a singularity. I thought that a black hole was more powerful then...

    How Can We Be Sure About Black Holes and Galaxies?

    Couple of questions here; I know they may sound dumb but here they go. I'm "new" with some questions, so be gentle. 1.) So, if a black hole has enough gravitational pull to pull in stars and what nots, and nothing can pull away from this force once it is to close, its consumed by the black...

    What I see in sky - Milky Way, other stars

    Isn't it just amazing. I just thought it was neat. I'LL have to do that DAVE. Thanks for the tip. I guess I never bothered with those cause when I was in grade school we looked at Saturn through a descent size scope, wasn't real big but enough to see the rings and I don't think they can hold...
