Galileo's support for the heliocentric theory (note that this is Copernicus's theory, not Galileo's) got him into trouble with the Roman Catholic Church. In 1633 the Inquisition convicted him of heresy and forced him to recant (publicly withdraw) his support of Copernicus. They sentenced him to life imprisonment, but because of his advanced age allowed him serve his term under house arrest at his villa in Arcetri outside of Florence.
Galileo developed the telescope, which allowed him to observe celestial bodies such as the moons of Jupiter and the phases of Venus. These observations provided evidence to support the heliocentric theory proposed by Copernicus.
It happened after Galileo published a book supporting the heliocentric theory that portrayed the Pope as a simpleton. The official view still supported the scriptural teaching that the Earth was at the centre. The church was unwilling to change its ideas until there was good evidence, which science did not have until the 18th century, so Galileo was taken to court, the lack of evidence was exposed and he recanted. The heliocentric theory, with the Sun at the centre, was eventually accepted when the evidence for it was discovered, which happened well after Galileo's lifetime.
Galileo did not contribute to the Big Bang Theory directly as his work focused on astronomy, not cosmology. The Big Bang Theory was developed in the 20th century based on evidence from observations of the universe's expansion. Galileo's contributions to astronomy include improving the telescope and making important astronomical observations, such as the phases of Venus and the moons of Jupiter.
Galileo did not have his own theory, he was a strong supporter of the Copernican theory, which was a model that contained circles and epicycles, just like Ptolemy's ancient model, but with the Sun at the centre and the Earth in an orbit between the orbits of Venus and Mars. Galileo promoted the theory not only as a scientific theory, which the Vatican supported, but he maintained it was the absolute truth, which got him into trouble. At the same time as Galileo, Kepler brought out the improved model with elliptical orbits, which was generally accepted as the best model many years later.
It's called the heliocentric theory (helios is sun) but it was not a fully fledged theory until well after Galileo's time.

It was Copernicus's theory and Galileo had very little evidence for it at the time of his quarrel with the Vatican, as he discovered when they put him on trial and asked for the evidence.

galileo galilei and galileo are the same person (that doesn't make sense.)
Newton explained his theory
Galileo did not have his own theory, he was a strong supporter of the Copernican theory, which was a model that contained circles and epicycles, just like Ptolemy's ancient model, but with the Sun at the centre and the Earth in an orbit between the orbits of Venus and Mars.

Galileo
The Jovian moons. Galileo had little evidence for the heliocentric theory, which was later (in the 18th century) generally accepted as correct after the laws of motion and the law of gravity showed that the Sun is by far the most massive object in the solar system and therefore must be at the centre. Galileo did not have the other major piece of evidence supporting the heliocentric theory, which is the parallax shown by relatively close stars as the Earth moves round its orbit. Parallax is extremely small and was impossible to observe in Galileo's time, and this was used to support the idea that the Earth is at the centre. Bessel made the first measurements of parallax in the 19th century.
