Sometime I too think that death is not the end of all my being
perhaps I shall pass through the mercurial mirror of life
Perhaps there is already
an anti-being representing my shadow in
an anti-spacefield in an anti-cosmos.
But more often I think that death is
a total annihilation of a set pattern.
One day I will go
and in my place
may be
a cactus will grow !!
Who knows ?
And what does it matter ?
For none will recognize me !!
Existence is not by itself.
Existence is by recognition.

Some more scientific insights on Antimatter and particles related from the world of science:
# It was the Nobel Prize winning physicist Paul Dirac who derived the equation that discovered antimatter in 1928.
# Antimatter: it’s matter—only different. It’s different because it’s
made of bizzaro particles that have the opposite electric charge from
what we observe in ordinary matter. In other words, the atoms inside of
antimatter have positive electrons, called positrons, hovering in an
excited cloud above a nucleus composed of negatively charged protons
called antiprotons.
# For some reason, in our neighborhood of the universe, matter edged out antimatter during the primordial era of the universe.
# Annihilation: When a particle and its antiparticle meet their masses are
converted into a photon with the amount of energy given by Einstein’s
famous equation E=mc2.
# These anti-particles are, literally, mirror images of normal matter.
Each anti-particle has the same mass as its corresponding particle, but
the electrical charges are reversed. Here are some antimatter
discoveries of the 20th century:

- Positrons - Electrons with a positive instead of negative charge. Discovered by Carl Anderson in 1932, positrons were the first evidence that antimatter existed.
- Anti-protons - Protons that have a negative instead of the usual positive charge. In 1955, researchers at the Berkeley Bevatron produced an antiproton.
- Anti-atoms - Pairing together positrons and antiprotons, scientists at CERN, the European Organization for Nuclear Research, created the first anti-atom. Nine anti-hydrogen atoms were created, each lasting only 40 nanoseconds. As of 1998, CERN researchers were pushing the production of anti-hydrogen atoms to 2,000 per hour.
CERN is indeed a real-life lab located in Geneva, Switzerland. |

# Matter
and antimatter are perfect opposites. So perfect, in fact, that when the
meet they annihilate leaving behind a flash of pure energy. Nothing else
remains. That's why science fiction writers like antimatter so much. To
them, antimatter annihilation is the ultimate clean source of energy.
It is the perfect conversion of mass (m) into energy (E) according to
Einstein's famous prescription E= mc2, where c is the speed
of light. The problem is, however, that antimatter cannot simply be harvested
or mined. It has to be made, and making it requires vastly more energy
than annihilating it produces. All the antimatter produced at CERN in
a year would provide barely enough energy to power a light bulb for a
few seconds.
# CERN's
new research machine, the Antiproton Decelerator (AD), allows scientists
to trap antimatter in electromagnetic cages where it can not come into
contact with matter. There they can study it at leisure, finding out,
for example, whether antihydrogen spectroscopy is the same as that of
hydrogen. Now that we know nature favours matter over antimatter, research
at the AD will help us to understand why.
