Mars suitable for Life?

Mars, the lovely red planet close to our earth, has shown some presence of the water and a research was conducted to see if life existed on mars.What is less known is how much water occupied the red planet and what happened to it during its geological march to the present. Mostly, evidence has pointed to a period when clay-rich minerals were formed by water, followed by a drier time, when salt-rich, acidic water affected much of the planet. Assuming that happened, the thinking goes, it would have been difficult for life, if it did exist, to have survived and for scientists to find traces of it.

Now a research team has provided a evidence for the presence of carbonates on Mars that shows that Mars could have been the home for watery environments in the past. The red planet close to the earth is neither too hot nor too cold. At the same time it is not too acidic. So it’s just the right place.

Finding carbonates indicates that Mars had neutral to alkaline waters when the minerals formed in the mid-latitude region more than 3.6 billion years ago. Carbonates dissolve quickly in acid, therefore their survival challenges suggest that an exclusively acidic environment later cloaked the planet.This could open up a range of environment on Mars.So the researchers say that the presence of carbonate mineral bolsters chances of environment on Mars.

History of Earth?

Lets look into how was this earth formed?

In science we must expand our conception of reality all the time. One of the very difficult concepts is the understanding of time. Everyone is conscious of the changes in the physical and biological world; they give us an awareness of time. The daily rhythm, the seasons, physical changes throughout a human lifetime are familiar concepts of time to us. Time is measured by change, but where change occurs over millions of years our own perception of time is on unfamiliar territory. To understand the rhythm of change of our planet and the effects it has on life on Earth we have to expand our perception of time.

The geological processes that shape the surface of our planet, move the tectonic plates, build mountains and erode them again work over millions of years. These forces provide the ever changing conditions for life, which adapted to those changes. But those changes did not go undetected. Our understanding of Earth has expanded tremendously in the past 100 years, and new technologies have provided further insight into Earth's dynamic and history.

Earth itself acts like a clock, rotating on its axis once every 24 hours. To read Earth's time it is necessary to look at the changes that have been recorded. To identify changes that occurred due to the geological processes of our planet we can look at rocks. They are key to both the past and the nature of processes. Life has managed to leave records of time and the changes it went through time as well.

Fossils are the remains of ancient organisms. Some looked very similar to life forms that are still living today. Fossils can be bones, teeth, shells, impressions of plants and even imprints of animal tracks. Fossils within a rock are a type of organic clock that tick by systematic radioactive decay of certain chemical elements, which permit us to measure with remarkable accuracy the number of years that have passed since the minerals in a rock crystallized.

Fossils are recorded in rocks much like your footprints are recorded on a beach. As you walk along the beach, if the sand is fine enough and soft enough, you will make footprints. If the wind and waves do not destroy your footprints, they may record your existence well after your passing.

Theory of Nature!

Nature, in the broadest sense, is equivalent to the natural world, physical universe, material world or material universe. "Nature" refers to the phenomena of the physical world, and also to life in general. Manufactured objects and human interaction generally are not considered part of nature unless qualified in ways such as "human nature" or "the whole of nature". Nature is generally distinguished from the supernatural. It ranges in scale from the subatomic to the galactic.

The word nature is derived from the Latin word natura, or "the course of things, natural character." was a Latin translation of the Greek word physis , which originally related to the intrinsic characteristics that plants, animals, and other features of the world develop of their own accord. This is shown in the first written use of the word , in connection with a plant. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socratic philosophers, and has steadily gained currency ever since. This usage was confirmed during the advent of modern scientific method in the last several centuries.

Within the various uses of the word today, "nature" may refer to the general realm of various types of living plants and animals, and in some cases to the processes associated with inanimate objects – the way that particular types of things exist and change of their own accord, such as the weather and geology of the Earth, and the matter and energy of which all these things are composed. It is often taken to mean the "natural environment" or wilderness – wild animals, rocks, forest, beaches, and in general those things that have not been substantially altered by human intervention, or which persist despite human intervention.

This more traditional concept of natural things which can still be found today implies a distinction between the natural and the artificial, with the latter being understood as that which has been brought into being by a human consciousness or a human mind. The Nature has gifted us with Lovely Mountains, Deep Blue Ocean, Snow Peaks, Untouchable Sky, Greenish Meadows and lots more.... The gift of Nature should be preserved to the best for a better life on Earth...

Suicide is a Crime!

A specialist in the field of suicide summed up the fact very well: "If you leave life with a restless soul, then you will arrive into the other world with a restless soul." Suicide victims commit suicide to "end it all," but, as it happens, it is only their beginning in the other world. Here are a few contemporary accounts that illustrate the otherworldly state of suicide victims.

One man, who loved his wife dearly, killed himself when she died. He hoped to reunite with her for eternity, but things turned out quite differently. When the doctor revived him, he said: "I was in a place quite different from where she was… It was a dreadful place… and immediately I realized that I had made a huge mistake"

Some revived suicide victims described arriving in a kind of prison or dungeon and they felt that they would have to remain there for a very long time. They recognized that this was their punishment for violating the established law, which requires that each person must suffer his share of sorrows. Having willfully thrown off the burdens placed upon them, they must carry even more in the world to come.

Another man, who survived death, tells the following: "When I arrived there, I understood that two things are absolutely forbidden — to kill oneself or to kill others. If I had decided to kill myself it would have meant throwing into the Face of God the gift he had bestowed upon me. To kill someone is to disrupt God's plan for that person".

When Life Began On Earth!

Earth is the only place in the universe where life is known to exist. The planet formed 4.54 billion years ago and life appeared on its surface within a billion years. Since then, Earth's biosphere has significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of aerobic organisms as well as the formation of the ozone layer which, together with Earth's magnetic field, blocks harmful radiation, permitting life on land.

The physical properties of the Earth, as well as its geological history and orbit, allowed life to persist during this period. The world is expected to continue supporting life for another 1.5 billion years, after which the rising luminosity of the Sun will eliminate the biosphere.

Scientists are still trying to unravel 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 on earth were primitive, one-celled creatures that appeared about 3 billion years ago. Then suddenly those single celled organisms began to evolve into multicellular organisms. Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans...

Views on Reincarnatiom!

Reincarnation is in my opinion an overly simplified concept, designed to be easily understood and accepted by the general population. But the theory of reincarnation falls down sharply when closely examined. That is, if you understand how standard linear time sense behaves in higher dimensional levels, i.e., time sense fluctuates.

As far as it goes, the theory of reincarnation is clear enough to explain some very complex esoteric matters in a simple way; without giving people headaches whenever they think about it. It also allows for the illusion of the continuation of present consciousness, unchanged and progressive, with only an occasional memory loss to mar its course; marking the division between each Re--Incarnation. This makes it easy for people to accept the bones of the incarnation process.

It gives them the benefit of a rational afterlife belief-system containing the simplified essence of the whole truth. This allows a measure of independence and security, and a reassurance of the continuance of self, i.e., life after death and reincarnation is a kind of immortality theory that people can easily accept.
