Reddit mentions of Antimatter

It is exactly the same as normal good old fashioned matter in every respect.... except one. In normal matter, the stuff that makes up an atom has an electric charge. In anti-matter, the charge is the exact opposite of what it is in normal matter.

When matter and anti-matter come into contact with one another, the opposite charges react and they obliterate one another.

Anti-matter is not a theoretical concept and should not be confused with dark energy. Anti-matter is real and it can even be produced at places like CERN. However, by its very nature, when an anti-particle is created it only lasts a fraction of a second because as soon as it interacts with regular matter (ie, pretty much everything in the universe!) it gets obliterated.

There are some great theories about anti-matter and how it started off in the big bang. It is suggested that during the big bang both matter and anti-matter were created in equal quantities, they all interacted together and obliterated everything....which would mean that there should be NOTHING left. But there is. We are here. So the question becomes, how did SOME matter survive. Why did the big bang create a tiny bit more matter than anti-matter. That raises all kinds of questions in the world of physics. It is even theorised that there could be entire regions of space and galaxies out there which are made up of only anti-matter and that we would never know about it as they look and act just like any normal galaxy, its not until they bump into some regular matter that they both go bang! It is a fascinating area.

I HIGHLY recommend picking up this book to learn more. It is written at a level that anyone can understand and it takes you through, step by step, the history of it and what it is and everything we know about it, and at the end of the book you will scratch your head and wonder just how you managed to comprehend all of it! http://www.amazon.co.uk/Antimatter-Frank-Close/dp/0199578877
