INFLATION AND MULTIVERSE

As we told earlier astronomers still trying to unravel the avalanche available in WMAP satellite. As it demolish the conventional theories and a new cosmological picture is raised called “Inflationary theory”. This is a major refinement of big bang theory.

In this inflationary scenario, first trillionth of trillionth second after the so called big bang a mysterious anti-gravity force caused the universe expand the much faster than previously thought at more than the speed of light. Within the fraction of second expansion in the factor of 10⁵⁰ . To imagine this inflation process, visualize the balloon which is rapidly expanding draw the small points on the surface of balloon before expansion. And see the dots now they become the circles .This is how our galaxies comes from the subatomic level to a gigantic figures of universe.

Now draw a small circles on the expanded balloon, this is our observable universe. Everything we can see with our telescopes. For the comparison, If our observable universe were small as sub atomic level then the original size of the universe was size of the observable universe. This is why the whole region of universe forever beyond our reach. By assuming early universe undergo this process of inflation one can explain many puzzling things of universe.

Even though explaining many things there is a question, which or what causes the inflation? What makes the antigravity to inflate the universe? There are more than 50 proposals to explaining the event but there is no consensus. There is no definitive proposal to answer the question what the engine behind the inflation? Because no one knows precisely how the inflation started, there is a possibility of inflation mechanism can takes place repeatedly. This idea was proposed by Russian astronomer Andrew Linde. He states whatever causes inflation, it may still works at the distant part of our own universe.

According to this theory, a tiny patch of universe suddenly inflated and ‘bud’ may be called as ‘daughter universe’ or ‘baby universe’. Which may again create the bud turns to a baby universe and this process happens repeatedly. This theory also means our universe may be a baby universe from a bud of more ancient mother universe.

To imagine this event visualize blowing soap bubbles into air and watch how the bubbles split into two. In this same way universe gives the birth to new infant universes. In this scenario big bang have been happening continuously. If this theory is true we may live in a cosmic ocean having endless possibilities. “MULTIVERSE” is most suitable than “Universe”

Linde “This theory is eternal. Self-producing or chaotic inflation”

Alan Guth, “Inflation pretty much forces the idea of multiple universe upon us”

“This theory also means our universe may be a baby universe from a bud of more ancient mother universe” if it is right what the other universe look like? Will they harbor life? What kind of law they obey? Shall we enter those universes and jump into hyperspace?
