The big bang theory predicts the universe has cooled to a few degrees above absolute zero and is awash in a faint glow of the 3K microwave cosmic background radiation.

A tremendous blank spot free of galaxies, stars, dark matter or black holes has been discovered in the distant reaches of space.

Scientists hope to solve the mystery of matter by mimicking conditions that existed just a fraction of a second after the Big Bang.

In addition to visible light, astronomers use ultraviolet, infrared, radio waves, X-rays and gamma rays to study planets, stars, galaxies, and other celestial objects.

The Big Bang remains the most trusted theory to explain how the universe originated. But, there are others which some scientists still believe to be plausible.

Both the steady state and big bang cosmological theories are based on certain fundamental cosmological assumptions and observations.

The steady state theory was a mid 20th century alternative to the big bang theory. It suggested that there was no moment of creation. The universe has always existed.
