Panspermia: Seeds
Everywhere
Humanity is one: All languages came from one
Panspermia: Seeds
Everywhere
Nasa and European and Italian Space
Agency spacecraft Cassini is beaming telemetry and images back from Titan the
massive planet sized moon of Saturn. The conditions in Titan resemble our earth
millions of years before life ultimately evolved. It has an environment rich in
carbon based molecules that are capable of spawning self replicating DNA.
Panspermia
literally means seeds everywhere. It is a theory, which maintains that life
bearing proto spores, is prevalent throughout the Universe. Life on Earth
originated when some of them landed on its surface and propagated. It also
suggests that life could have existed in another planet and moved to Earth.
Humanity is one: All languages came from one
Humanity is one, yet we notice divisive
tendencies. Dr.Russel Grey an evolutionary biologist at the University of Auckland
in New Zealand
published his results in Nature magazine co-authoring with his colleague
Quentin Atkinson. In his submission he expressed confidence that a family tree
of human languages could be constructed and its branching points dated.
If this happens a wonderful new window
will be opened into human past. As biologists had drawn the family tree of
genes and species, linguists too have started to use same mathematical tools to
build a tree, which traces to the only one language spoken once upon a time
which now had divided into 6000 and more languages. Dr.R.Madhivanan, a great
Tamil scholar is emphasizing the need for language archaeology to dig at the
roots of the first human language
Ultimate Universal Theories
Times of India in its editorial on 12 th
October 2004 titled “Ends and Means” explains how Universal theories are coming
to the fore in the following words. Quote:“ Einstein wanted to end it all,
scientifically speaking. After his special and general theories of relativity
earlier in the last century had revolutionized physics, he spent his last 30
years of life till his death in 1955 trying to find an even more generalized
concept that would unite all the forces of Nature. Called the unified theory it
was an attempt to understand every physical interaction and present it in as
simple a form as e= mc2. He was only partially successful. Since then, though
researchers around the world have striven hard in their efforts to lay their
hands on what has come to be known as theory of everything-something that would
comprehensively explain the entire universe from the smallest subatomic
particles to the most massive galactic structures.
Discovery of New Species
Nature had been working overtime to
create us humans in a variety of species spanning millions of years. This
process had not reached perfection in homosapiens. A recent discovery unveils
of a completely new species of humans who lived from 90000 years ago as late as
12000 BC before apparently becoming non-extinct. Identified by Australian and
Indonesian scientists from a cache of fragmented bones buried in the sediments
of a limestone cave on the remote Indonesian island of Flores ,
it has been officially named homo-floresiensis. They were not taller than a
meter with brain size of a grape fruit.
Now we should also know what is in
store in Nature and wherefrom dangers come to our earthly existence.What is
happening in Nature?
