The most popular theory of our universe's origin centers on a cosmic cataclysm unmatched in all of history—the big bang. This theory was born of the observation that other galaxies are moving away from our own at great speed, in all directions, as if they had all been propelled by an ancient explosive force.

Before the big bang, scientists believe, the entire vastness of the observable universe, including all of its matter and radiation, was compressed into a hot, dense mass just a few millimeters across. This nearly incomprehensible state is theorized to have existed for just a fraction of the first second of time.

Big bang proponents suggest that some 10 billion to 20 billion years ago, a massive blast allowed all the universe's known matter and energy—even space and time themselves—to spring from some ancient and unknown type of energy.

The theory maintains that, in the instant—a trillion-trillionth of a second—after the big bang, the universe expanded with incomprehensible speed from its pebble-size origin to astronomical scope. Expansion has apparently continued, but much more slowly, over the ensuing billions of years.

Scientists can't be sure exactly how the universe evolved after the big bang. Many believe that as time passed and matter cooled, more diverse kinds of atoms began to form, and they eventually condensed into the stars and galaxies of our present universe.

What Heaven And Earth sets out to do is restore a sense of scientific perspective to a debate which has been hijacked by ‘politicians, environmental activists and opportunists extinctions that climate changes are cyclical and random is only 0.001 per cent of the total CO2 held CO2 is not a pollutant but a plant food earth’s warmer periods were times of wealth and plenty.

Climate change study shows Earth is still absorbing carbon dioxide

The Earth has developed stores to absorb excessive levels of carbon dioxide, according to a study that challenges the conventional thinking on climate change.

First formulated by Lovelock during the 1960s as a result of work for NASAconcerned with detecting life on Mars, the Gaia hypothesis proposes that living and non-living parts of the earth form a complex interacting systemthat can be thought of as a single organism. Named after the GreekgoddessGaiaat the suggestion of novelist William Golding, the hypothesis postulates that the biosphere has a regulatory effect on the Earth's environment that acts to sustain life.

Carbon dioxide and other gases warm the surface of the planet naturally by trapping solar heat in the atmosphere. This is a good thing because it keeps our planet habitable. However, by burning fossil fuels such as coal, gas and oil and clearing forests we have dramatically increased the amount of carbon dioxide in the Earth’s atmosphere and temperatures are rising.

The vast majority of scientists agree that global warming is real, it’s already happening and that it is the result of our activities and not a natural occurrence. The evidence is overwhelming and undeniable.
