Clusters
They give you some place to travel to.
Not with present human technologies.
New stars together are called a star cluster.They usually travel in space together, for there gravity keeps them in a group.
to explore many different planets, galaxies, comets, possible planets we can live on, etc.
they see the past when they look up and see the galaxies. its looking back in time because light can take years to travel to earth and so its like their looking at the youth of the galaxy.
Binary Stars
Black holes travel through space just as anything else (i.e. galaxies, stars, etc) travels.
space ships. some people think that wormholes can lead to other galaxies
no coz it will take lot of years, invent a spaceship
They give you some place to travel to.
any time I guess?
maybe but i think not
The Stargate program is from a TV show called Stargate. It has many sequels. It's a about a gate that you can travel through to other planets in other systems and galaxies. I recommend typing in Stargate SG-1 in to the search engine.
Fever
I assume for the same reasons that our civilization wants to travel through outerspace, visit other galaxies and explore planets.
Data packets that are in a group and sent together are called a frame. Data packets do not have to travel through unnecessary nodes so they can be sent quickly.
Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.
