Very interesting - some of the comments made my brain ache, though.  O_o

Oh yikes I didn't even scroll down to read those. Sorry about that. I usually ignore comments and forgot those pages have them.

I was amazed to read that a black hole could be the size of an atom? That's incredible.

I'm just glad I realized that it was a nutcase (troll, perhaps?) before I responded to more than one.

Black holes have frightened me (terrified actually) ever since I was a kid... space in general does. I guess I have a fear of vastness, and emptiness :/ I see a documentary on space, and just something inside me curls up and hides.

Very interesting.

Although is it just me or do a few of them look like they were made by some kind of drafting/animating software? They just seem to...clean, for lack of a better word

Yes, it refers to those as artists' renderings in the captions.

So you're saying that when you gaze into the abyss the abyss grows also in you?

To be fair, space isn't empty. Its permeated by a plasma of stray particles at a temperature of about 3K.

Well, not empty in an absolute sense.  But the amount of empty space dwarfs the volume of particles.  Though, I guess that's true everywhere in the universe, isn't it?  Even our bodies are mostly empty space.

It makes me feel small and completely defenseless. Any kind of open area that feels still, or dead... like, a field won't do it for me. Theres hills and breeze and other things that remind me this is a natural place. But if I'm in an empty stadium or underground car park, I get this paranoia that I'm being watched and if whatever was watching decided to come for me, I'd never be able to outrun it.

Space gives me the same feeling... huge, still, dead, infinitely imposing.

I was trying to read the comments but it seems they started that traditional Religion vs Science war there, so lost interest and log off...

*nods*  I actually responded to one saying that time can't exist in space, since time was dependent on the rotation of the Earth or summat.  (OT - Firefox recognizes 'summat' as a word?)  I left a definition of a second in terms of radioactive decay; a la the atomic clock.  Then I realized I was talking to a brick wall.

On the plus side, you could measure exactly how long you were talking to the brick wall.

The video here shows how they make those pictures look so pretty. =3

I saw this a while back and found it very interesting.

It would be cool if they found out that white holes exist. Just a rift where matter comes spewing out all warped and stretched beyond it's means.

Isn't that the theory of what quasars are?

Well I remember reading somewhere that a black hole would have to consume 10 stars each year to produce the same output as a quasar. So that would be a super massive black hole.

I've been fascinated by black holes since 7th grade, when I got a copy of Asimov's 'The Collapsing Universe'.  ^_^>  One book I read compared quasars to a tube of toothpaste with a pinhole in it, being run over by a steamroller - a rather indelible image.

I actually ordered Asimov's book The Foundation just last week it should be coming in the mail tomorrow. I can't wait to read it. It's hardback like all my sci-fi books :P

I just finished reading Phil Plait's Death from the Skies, so this thread instantly gave me a massive nerd-rection. It's pretty great at allaying fears about space, I would say. It's a pretty inhospitable universe, but it's anything but dead.
