What are they referring to - the black space between the stars in the sky?

It's the matter that provides the gravitational force that stops our galaxies from being flung apart by angular momentum.  It's called dark because we can't see it, but we know it's there because it bends light

Yes, it was night but me, my mom and my two little sisters saw the silhouette of a black disk in the sky, (it was really close to us) and it had red and green lights going around it. And almost as soon as we saw it it was gone. I know it wasn't an airplane or anything man made.

The universe is expanding as the speed of light.  If you stand at the outer edge of universe, you will see black and darkness on both sides because light emitted from stars hasn't reached you yet and nothing is on the outside of expanding universe.

it is the difference in brightness between the stars and any astronaut, cosmonaut, space shuttle, or international space station.  the stars are just too dim.  a much longer exposure time is needed to photograph dimmer objects.  ask someone who knows about photography.\n\nhttp://en.wikipedia.org/wiki/Photography

A star is stationary object and a black hole is a result of dying star. Black holes are stationary objects.\nThey posses a great gravitational force. It is so great that it can even suck in light.\nDue to such gravitational force it makes objects near it to revolve around it with tremendous speed.\n\nThe closest black hole to earth lies just 1,600 light-years \n(1 light year = 9.4605284 × 10^15 meters ) from Earth on the way to the centre of the Milky Way in the direction of the constellation Sagittarius.\n\nBut if you want to test the above facts and experience it yourself then just wait till sun becomes one black hole!!!! (after around 5-6 billion years)  (Sun can also become neutron star or nebula so may be you cannot experience it!!)

Have you ever looked at the sky and seen a shooting star?\n\nThese are meteors burning up as the enter the atmosphere.  Is this what you are talking about?

Just what the he[[ does that have to do with astronomy and space?????????????

Once you leave the Milky Way you are not outside the universe. The Milky Way Galaxy is one of many known galaxies in the universe. There are probably billions we don't know about. "Goodness knows where" is inter-galactic space.\n\nInfinity means "forever". It is not necessarily a measurable distance or time. We're not sure if the whole universe is infinite. We can't even see most of what is out there. The estimated size of the observable universe is 7.4x10^26m (that's really, really, really, really big). Beyond that we're not sure yet.

It is French... and it is not good. It looks like a translator was used.\n\nIt seems like it is supposed to be something like this: In place of taking certain images from the star. It has put more on it. Ok at I can say I at least tried.\n\nDoes not make much sense.

1) At what latitude do you live?\n2) What time of night is it?\n3) What direction are you looking in the sky?\n4) How strong are background/city lights where you are?\n\nWhat you are experiencing is called "averted vision".  The portion of our retina most sensitive to faint light is not directly behind the pupil, but off to the side a bit.  You are looking at a deep sky object (star cluster, nebula or galaxy), but to know which one for certain, I need the answers to the above questions.  At this time of year, it is most likely the Pleiades or the Orion Nebula.

this is a weather term - it means an area of high pressure, leading to little or no clouds in the sky (i.e. hot weather in the summer, or cold nights in the winter).

One theory is that every galaxy has a super-massive black hole at its center, which is slowly drawing all its stars into it. Plus the galaxies are being drawn into each other. If this continues, all matter will ultimately be drawn into one enormous black hole, which will collapse into itself and then...BANG! It starts all over again. Of course, there will be no humans around to witness it. Our star would have been destroyed long before that...

Its refering to sunlight. Only sunlight goes low or dim (We were afraid that the light was too low)

If the Andromeda Galaxy is 2.5 million light years away and it's the only galaxy on Earth to be seen by the naked eye, it leaves us to wonder how far it really is.\n\nPersonally, I googled it. I couldn't find a thing relating to the blank nothingness further than the universe.\nI only looked a little bit, but there are very few educational guesses on the Internet.\n\nMaybe you should try. Googling that is. Maybe it's you who'll find the right words to search it in.  \nThe words stumped me so the was probably my problem.\n\nGood luck on finding the answer!\n-Marissa
