My mind blew straight out my toes when I read a little about black holes. A micro one has the mass of the moon, but in a space that is 0.1 mm?? How much does the moon weigh exactly?

Life was most likely in our galaxy. I was watching this episode of national geographic that said long, loooooong ago Mars most likely had life supporting elements and could've actually had life! Apparently though, once a planet loses it's thriving conditions that support life, it can never gain them back. There's a planet that really interests me, it's a water giant. It's this huge planet with nothing but water that's so deep, it makes our deepest oceans look like you can touch the bottom with your feet and have your head above water. It also orbits a sun, so they're saying it potentially could have life. Also, everyday on this water giant is sunny with no clouds, considering it's nothing but deep oceans. I could have some facts wrong, but it's just so mind boggling and so interesting, I can hardly contain myself. Sorry for being so off topic though. . . .
I have not learned of any water-covered exoplanet discovery. Do you know any sites or articles related to it?
No it isn't. Besides the fact that there's really no way we'd be able to know something like that about a planet that's 20 light years away, it's likely to suffer from a runaway greenhouse effect like Venus.

Never attribute to malice what can adequately be explained by incompetence.
I think that "Black Hole" is somewhat misleading name as it is accurate. I think it's just a spherical vaccum that will one day in the far future combine with everything else, reach such an immense size that it will collapse on itself and forming another Big Bang
Although I think you're referring to 'vacuum' as being a generic term, black holes are not vacuums.
Vacuums consist of relatively no matter, while black holes are extremely (possibly infinitely) dense matter that has an extremely powerful gravitational effect.
Well I thought that was obvious but apparently not. I meant that Black Holes are basically cosmic vacuum cleaners, not that they use actual vacuum. As for the rest of your post that I cut out, it was an interesting read. I had no idea that Black Holes slowly died which means that something is able to escape the hole or is the radiation created at the event horizon? Because if light is matterless then why do radiation escape if not that it is created at the event horizon or that light does have some form of matter in it.
Sorry about the vacuum thing, I just had to be specific and clarify, for the sake of discussion. You never know what some people believe on the internet these days.... lol
And yes, actually they do believe that the radiation is created at the event horizon. :biggrin.gif:
Although, we do not currently have proof that black holes emit radiation (they are looking for the proof now, with various satellites) but Quantum mechanics concludes that black holes must emit the radiation.
I'm not familiar with why this is, but scientists seem to believe that it is a likely conclusion.
As such, the theory indicates the radiation is formed from 'virtual particles', which are particles that normally cancel each other out... but the black hole's energy forces them apart, turning them into regular matter (bosonic matter).
So, if they do not emit this radiation, our entire concept of quantum mechanics must be re-evaluated... Which is still very much a possibility.

No problem. And I saw a documentary series with Stephen Hawking the other day and IIRC, if the black hole is small enough you can see it glow because of the radiation it puts out. I think the episode was called Black Hole. Had alot of stuff about black holes. It was where I fleshed out my big bang theory. Which is also the best sitcom EVER created.

Read the article in my first post on this thread, it explains how it most likely is a world of water. I don't really think it suffers from a runaway greenhouse gas effect like Venus though(never no though). Gliese 581 c is a planet in the "super earth" family. Super earths are planets that are similar to Earth and may have the means to support life like Gliese 581 g. It explains it in the video how they found it, where it is, and what the conditions are potentially like. They found Gliese 581 c a good while back and have really been studying it. I really wouldn't argue with the astronomers "hypothesis" though. They have a good basic outline of what the planet is potentially like. Also, astronomers observed the world of water, they all believe in the fact that it is a world of water(I'm sure not all astronomers believe in the fact) and judging that the planet is ten-times bigger than our Earth, the ocean on that super earth is pretty freaking deep. The article in my first post on this thread explains it.

Neither of the articles in your first post mention Gliese 581c. So, no, they don't explain that. One of the articles was a newspaper article. Not really a go-to source for accurate scientific reporting. That article doesn't even talk about any specifically discovered planets, it only goes over calculations for hypothetical situations. The NG article is about GJ 1214 b, which is a completely different planet orbiting a completely different star. Additionally, the article's the same old sensationalist reporting of "it could have water because it's in the habitable zone!". Except that there's no evidence of water.

They explain the type of planet it is, not much info on the web obviously if i used a newspaper article. If you haven't seen the youtube video I posted, you should check it out. Yes, the water isn't proven, but the statement that it could is amazing. What I posted earlier did not include much real facts, I'm aware and am sorry for any confusions or any arguments. EDIT: I now realize I sound a little idiotic. . . . Should get some facts straight before I get overly excited and post what I think I know.
. . . . . Read it again, more information lol.
