It's raining outside now and I'm having
a cup of coffee and curious about the
behaviour of our nature. Meet this
gentleman Mallikarjun and Nagabhushan.
Both of them lives in Bangalore and a
very close friend of mine
These two gentlemen also have a curiosity
about nature too. They often come up with
so many questions about nature's like
kids and keep on thinking on those
unresolved answers. And they have
requested me to make a video on their
choices of three topics 1. The origin of
life - Big Bang Theory. 2. Why Thunder
Storm happen  and 3. Where does the Air come from. This is the perfect day to respect
their request to me. This video is
dedicated to Mallikarjun and Nagabhushan
as a gesture of their love and trust in
me. Friends this video is also for you
who loves nature and are curious about
the wonders of nature the same way as I
do
How old is the universe and how did it
begin?.  Throughout the research history,
countless myths ,hypothesis and
scientific theories have tried to
explain the universe's origin. The most
extensively accepted simplification is
the Big Bang Theory. In 1927 the Belgian
catholic priest George's Lemaître
proposed an expanding model for the
universe to explain the observed
Redshifts of spiral nebulae. He based his
theory on the work of Einstein and De Sitter
and independently derived Friedman's
equation for an expanding universe.
In the very beginning of Earth's history,
this planet was a giant red heart the
roiling, boiling sea of oceans of magma.
The heat had been generated by the
repeated high-speed collisions of mass.
Smaller bodies of space rocks that
continually stumped together as they
collided to form our current planet.
As the collisions gradually decreased, the
primitive earth began to cool forming a
thin crust on its surface. As the cooling
continued, water vapour begin to escape
and condense on the arts early
atmosphere.
cloud formed and storms raged, raining
more and more and water down on the
primitive earth cooling the surface
farther until it was flooded with water,
Forming the Seas
Scientists are still trying to resolve
one of the greatest mysteries of earth.
When did life first appear and how did
it happen?. It is estimated that the first
life forms. One celled creatures
that appeared about 3 billion years ago.
Then suddenly those single-celled
organisms began to evolve into
multicellular organisms. Then an
unparalleled profusion of life in
incredibly complex forms began to fill
the oceans.
The Miller-Urey experiment was a
chemical experiment that stimulated the
condition at the time to be present on
the early Earth and tasted the chemical.
Origin of life under those conditions.
The experiment used water, Methane,
Ammonia and Hydrogen. The chemicals were all sealed inside sterile 5 liter Glass
flask connected to a 500 ml flask, half
full of water. Then by going through a
stage of evaporation, continuous
electrical spark and condensation, they
have simulated lightning in the water,
vapour and gaseous mixture condition like
primitive earth. At the end of one week of
continuous operation and processing,
through a series of chemical reactions
Miller identified five Amino acid
present in the solutions. "Amino Acid" the
first building block of life.
Still scientists are finding new
indications to find out how life first
began on earth in some really
interesting places --- "The Deep Ocean"
It's the earth where we live in and the
life on earth swims at the bottom of a
colourless ocean of air. The presence of
air on our beautiful planet earth began
before the planet even formed.
During the BIG-BANG various gases such as Helium, Oxygen and others were together
which were distributed to its part when
that big ball of heat broken.
Fortunately our earth got a major part
of the surviving as Oxygen. Volcanic
eruptions also gave these gases which
occurred very frequently in those
historic times. This forms the base of
atmosphere. Earth's current atmosphere
developed through a sequence of event
that started with the coalescing solar
system.
Air is the invisible mixture of gases
that surrounds the earth. Air contains
important substances such as Oxygen,
Nitrogen and most species needed to
survive. The wind is, air in motion. It is
produced by the uneven heating of the
Earth's surface by the Sun. Some part of
the art received direct rays from the
Sun, all the year and are always warm.
Other places receives indirect rays. So
the climate is cooler. Warm air which
weighed less than cold air, rises up.
Then cool air moves in and replaces the
rising warm air. This movement of air,
what makes the wind to blow. Sea has a
greater heat absorbing capacity than
land. So the surface of the sea warms up
more slowly than the land. The warming
air expands and becomes less dense,
decreasing the pressure over the land.
The air above the sea has a relatively
higher pressure causing air near the
coast to flow towards the lower pressure
over land at night the land cools off
faster than the ocean due to differences
in their heat capacity. If the land
becomes cooler than the adjacent sea
surface temperature, the air pressure
over the water will be lower than that
of the land, setting up a land breeze
blowing from the land to sea. The land
breeze will die once the land worms up
again in the next morning.
Thunder is the sound caused by lightning
and depends on the distance and the
nature of the lightning. The sudden
increase in pressure and temperature from
lightning produces rapid expansion of
air within and surrounding the path of
lightning strike. In turn this expansion
of air creates a sonic wave, often
referred to as a "thunderclap" or "peal of thunder"
A thunderstorm, also known as an electrical storm.
Lightning is an electric current. Within
a cloud way up in the sky, many small
pieces of frozen raindrops bumps into
each other as they move around in the
air. All of those collisions create an
electric charge. After a while the whole
cloud fills up with electrical charges.
The positive charges of protons form at
the top of the cloud and the negative
charges or electrons form at the bottom
of the cloud.
Since opposites attract.
That causes a positive charge to build
up on the ground beneath the cloud. The
ground electrical charge concentrates
around anything that sticks are such as
mountains, people or single trees.
Lightning is approximately 54,000
degrees of Fahrenheit. That is six times
hotter than the surface of the Sun.
Thunderstorms occur in a type of cloud
known as Cumulonimbus.
They are usually accompanied by strong
winds and often produce heavy rain and
sometimes snow, sleet or hail. Strong or
severe thunderstorms include some of the
most dangerous weather phenomena
including large hail, strong winds and
Tornadoes
The storms can form and develop in any
geographic location, but most frequently
within the mid-latitude, where hot moist
air from tropical latitudes collides
with cooler air from polar latitudes.
Thunderstorms are responsible for the
development and formation of many severe weather phenomena
