Antimatter.
This could be the source of future energy for the world, considering today's dangerous situation (Global Warming)
Antimatter is a source of vast amounts of energy with the following features that I recall:
1. It provides many times more energy than nuclear fission.
2. It doesn't pollute the environment while most (including Nuclear) do.
3. It is 100 percent efficient! (Nuclear is 20 percent)
What you and I see daily is matter. Antimatter is something that exactly balances matter. That is to say, if equal amounts of matter and antimatter are present, they fuse giving rise to huge amounts of energy and form NOTHING. Reverse it. NOTHING AND SOMETHING ... are the same.
Now, they say, there are ANTIMATTER galaxies in the universe too.
Anyway, it is said that our universe was born due to a very small amount of IMBALANCE in the amount of Matter and Antimatter, as small as 1 in a million. This is called the ultimate ASSYMETRY.
