The Earth has 4.9 billion years life MIL, Nov 25, 2004. Arif Nisar The Earth is the most miraculous creation. It is the unique part of the Solar System, rather solitary in several respects. This is the only planet so far known having life in whole of the Universe. There are millions of other Earths, but they are still the process of detection. So far the life of the Earth is concerned, the opinions of scientists are divided. Some scientists say that the Earth was born somewhere 3000 million years ago. Some say that it was born 10,000 years after the Sun was ignited about 4.5 billion years ago. Some say that the Earth made its final appearance as a planet about 30 million years than previously acceptable research of 60 million years after the Sun condensed in the center. Some scientists claim that the magnetic field of the Earth is getting weaker and weaker and it may disappear in the next millennium. There is another study, which claims that the Earth shall disappear after 7.5 billion years before it is swallowed by the Sun. "The disappearance of our planet is still 7.5 billion years away, but people really should consider the fate of our world and have a realistic understanding of where we are going," said UW astrophysicist Donald Brownlee. Peter Ward. Some experts have revealed in their latest research study that Mercury, Venus, Earth and Mars, the planets of the inner Solar System started forming 10,000 years after the nuclear fires of the Sun were ignited about 4.5 billion years ago. Some chemical isotopes were analyzed and the Earth's crust had indicated that it had formed about 50 million years after the Sun, but now Jacobsen has contradicted it. According to "Two Big Bangs Created the Universe" Formed in Eternal Space authored by Dr. Raj Balev, the Earth ranks 3rd from the Sun, and is one of the four rocky planets operating in the inner circle of the Solar System. The Sun and the Solar System were born in the pandemonium conditions about 4.6 billion years ago. I contacted Dr. Raj Baldev, Indian Cosmo Theorist to have his comments. He gives current scientific understanding of the Universe, planets and stars, as well as parameter of life of the Earth. He said: "After the Sun was born, the grains of material from the cloud accumulated into solid deserts of material which grew larger and larger with pace of time and ultimately took the shape of different planets including the Earth. He added that the Sun couldn't become black hole so it would not be able to swallow the Earth. The Earth shall explode after 4.9 billion years when it loses its total energy and would fail to retain its structure and would explode like a dead star."
