Well evrything that we see around oursleves has an opposite....like GOOD vs BAD,Heaven vs Hell,Positive vs Negative and much much more.....(like me and my brother :))

Well there is one more thing ,i.e., MATTER .... now what is matter ...according to our science theory books Evrything is matter ....
Now a Question Arises...if everything is Matter then Wht is the opposite of Matter and is there is one then where is it....???
Currently while reading the book Angels & Demons (by Dan Brown) , i came across the concept of Anti-Matter which is deemed to be the opposite of Matter...
After searching on the Internet i got lots of info on Anti-Matter .. like "Antimatter is around us each day, although there isn't very much of it," says Gerald Share of the Naval Research Laboratory. "It is not something that can be found by itself in a jar on a table."

Antimatter is a fundamental particle of regular matter with its electrical charge reversed. The common proton has an antimatter counterpart called the antiproton. It has the same mass but an opposite charge. The electron's counterpart is called a positron.

To better understand the elusive nature of antimatter, we must back up to the beginning of time.
In the first seconds after the Big Bang, there was no matter, scientists suspect. Just energy. As the universe expanded and cooled, particles of regular matter and antimatter were formed in almost equal amounts.
But, theory holds, a slightly higher percentage of regular matter developed -- perhaps just one part in a million -- for unknown reasons. That was all the edge needed for regular matter to win the longest running war in the cosmos.
"When the matter and antimatter came into contact they annihilated, and only the residual amount of matter was left to form our current universe," Share says.

I guess anti-matter holds the key to our future hunger for power resources ..but i hope it doesn't follow the way followed by Nuclear Energy...
