A galaxy without stars?

So it would seem from the evidence so far.

There's a discovery recently of a collection of space that is gigantic enough and is emitting more energy collectively than should be otherwise existing in 'empty' space. They believe it's a galaxy that can't be seen, hence "galaxy without stars." There's a better explanation on Space.com, check it out. Very interesting stuff.

I just read the article about that dark galaxy -- interesting. How about something I was thinking that might explain the reason light can't be seen from this galaxy: maybe, just maybe, there is a very massive object with immense gravity within the galaxy that will not allow light from stars to get out of it.

Wouldnt that also mean that all the stars are getting pulled in as well.. a BH that massive wouldve swallowed up the entire galaxy.

I wonder instead if its possible that the galaxy is so old, maybe the first galaxy created, that all of its stars are burnt out.

I guess so... a massive galactic black hole WOULD have to pull in all the stars if there was no light comming out at all... wow, that would really be massive indeed.

Yea, it sounds logical that that galaxy might be so old that all the stars could be burnt out.

Hey, maybe some other galaxy stole that galaxy's stars a long time ago or something.

I don't think this is possible as the massive amounts of energy that are found at the centres of galaxies are constantly forming new stars from the older materials. I might be wrong.

Maybe it's an object that we haven't discovered before that is doing it.

Or perhaps theres some sort of material between us and the galaxy that's absorbing everything in the spectrum except for radio waves. A universal low-pass filter.

Hmm... the material would have to be quite massive to do that. How about this long shot: The galaxy may be surrounded by a dark matter bubble.

That would require even more material. What I was talking about is for example, something as small as your hand placed directly in front of your eyes will blind you of everything. Relatively speaking the material may be very close to us, directly between us and the galaxy.

Maybe there is no gallexcy there at all, just a mass of energy! Scientists have seen energy turn into matter and vica versa. could be masses of energy that cant turn into matter for some reason.

Or

There are no stars in this galaxy just a big gas cloud and planets!

I see, but if it was closer, wouldn't astronomers have discovered it already?

I see, ...but what kind of energy could do this? It seems that right now, scientists think it could be dark matter (theorized) within the galaxy, but man... that's a lot of dark matter to fit in an entire galaxy.

Well by closer it could be at the outer edge of our galaxy, maybe just big enough to cover up the other galaxy.

Or maybe scientists have just detected a huge radio source that they THINK is a galaxy but may turn out to be something else entirely.

Okay, I get what you mean now when you say between us and it.

Damn... if it turns out to be just a radio source like you said, heh... that I think that would be the scientific joke of the year, since they said it was a galaxy.
