The Universe

The Universe is a huge wide-open space that holds everything from the smallest particle to the biggest galaxy.... 
No one knows just how big the Universe is... Astronomers are trying to measure it all the time but so far an exact size has never been found and probably never will be. 
About 13 billion years ago, a powerful explosion called the Big Bang took place and this set the Universe into motion and it continues today. 
This motion may stop, change direction, or keep going forever. 
The universe is so vast and full of surprises....no one exactly knows what may happen next....every second,many stars are born and at the same time many of them die. All the stars nebulae,supernovas,quasars ,black holes and all make the universe a truly wonderful place to study. 
one thing though which bothers me as well as many others is a question... 

"Is anybody out there?" 

through this blog i'll bring forward whatever i know about the universe,and also about our ventures into space....
