what was the big boom?

Answer 1

I think it is Big Bang, not Big Boom.

Big Bang Theory is currently accepted explanation of the beginning of the universe. The big bang theory proposes that the universe was once extremely compact, dense, and hot. Some original event, a cosmic explosion called the BIG BANG, occurred about 13.7 billion years ago, and the universe has since been expanding and cooling.

The theory is based on the mathematical equations, known as the field equations, of the general theory of relativity set forth in 1915 by Albert Einstein. In 1922 Russian physicist Alexander Friedmann provided a set of solutions to the field equations. These solutions have served as the framework for much of the current theoretical work on the big bang theory. American astronomer Edwin Hubble provided some of the greatest supporting evidence for the theory with his 1929 discovery that the light of distant galaxies was universally shifted toward the red end of the spectrum. Once “tired light” theories—that light slowly loses energy naturally, becoming more red over time—were dismissed, this shift proved that the galaxies were moving away from each other. Hubble found that galaxies farther away were moving away proportionally faster, showing that the universe is expanding uniformly. However, the universe’s initial state was still unknown.

Answer 2

The big boom suggested was that it could be the biggest explosion ever seen on the planet as researchers found a crater in Antarctica that was created by a meteor the size of Syndey, Australia. Scientists who found the crater say it could explain the global extinction in the Permian-Triassic period when all animal life on Earth died out, clearing the way for the dinosaurs. The also believe it probably created the continent of Australia, forcing it to break away from the existing land mass. “A meteor that size would have punctured right through the crust of the Earth and caused enormous damage to the planet," said Australian scientist Dean Archer. “In that period 95 per cent of life on Earth was destroyed.

Answer 3

It is widely accepted that something big hit the earth, and left behind the massive Chicxulub crater in the Yucatan. Lurking under the ice in Antarctica's Wilkes Land are the gravitational signatures of what may be a crater that's about twice as large as the one in the Yucatan.

The area in question is surrounded by a 300-mile-wide zone of roughly circular ridges. Using satellite measurements of gravitational attraction, the researchers detected a region of material that appears to have been left behind by a large upwelling of molten rock from the earth's mantle. That sort of signature can be caused by the bounce back that occurs immediately after a large impact. If this is the correct interpretation, the resulting crater appears to have been caused by a meteor in the area of 30 miles wide, or about 4-5 times the one estimated to have caused Chicxulub. The best guess as to the timing of the impact places it at about 250 million years ago.

Answer 4

The big bang was the theoretical beginning of the universe.

It was supposedly all matter being compressed to less than the size of an atom. The resulting energy build up caused an explosion that went about creating matter out of nothing.

A comparison would be an explosion in a vacuum, if that were possible. This theoretical explosion is causing the universe to expand. Based on computations of the expansion, scientist can make estimation on the size and age of the universe.
