An open universe is a universe where all of the galaxies and stars and everything in the universe keep expanding with nothing stopping them. This theory says that the galaxies and stars will keep going further and further from the centre of the universe until everything dies off. This is the opposite of the closed universe theory where everything will expand, and then something will cause a turning point and everything will contract until everything there ever was will fit into a space the size of the dot at the end of this sentence. Then, possibly another 'Big Bang' will happen and start everything over again. :)
Universe: It contains everything.
There is no singular star in the center of the universe. Our universe is vast and does not have a center. Stars are spread throughout the universe in galaxies, and our sun is just one of the billions of stars in the Milky Way galaxy.
Current scientific meaning of the word universe, is that it includes everything. So there is only one universe - The Universe However the new idea of String Theory is starting to suggest that there may be more than one universe, and so the meaning of the work universe may change in the future. The scientist Brian Greene is one of the leading physicist working on this theory. Science-teacher
No there's millions of sun's if you see at night you will see stars!A star is a sun!
One way scientists use to calculate the age of the universe is by measuring the rate of expansion of the universe since the Big Bang. By studying the cosmic microwave background radiation, astronomers can determine the age of the universe to be about 13.8 billion years.
there is no difference. they are both 42.
it will either be open or closed universe look it up
An open system is one that exchanges both matter and energy with its surroundings. For example, suppose Earth is a system and the universe is its surroundings. Earth is an open system, since it can exchange both energy and matter with its surroundings.
NO, just the stores.
Yep, it's open all year round.

The Universe keeps on expanding in all the sides so no one can really tell how high is the universe.
Wormholes open up holes in space that once you enter one it could take you to another place in the galaxy or time. Hence the name wormholes.
One uses "a" because although the word universe begins with a vowel, it's pronounce as if there were a "Y" at the beginning. Wrong: An universe Right: A universe
the most popular one is the big bang. it states that the universe was formed in one gigantic explosion.
The galaxy, the one we are in, we call the Milky Way. It is one of billions of galaxies. These galaxies and everything else make up the universe. Compared to the universe galaxies are small fry.
A universe is a very big realm of darkness with galaxies in it. and there are billions of galaxies in the universe! One of those galaxies is our solar system, and in that solar system is our planet. There probably is even more then just one univserse. O_o Well... Galaxies are within the universe and a universe is defintly bigger then a galaxy
