The Big Bang Theory was first proposed by Belgian physicist and Catholic priest Georges Lemaître in 1927, predating its popularization by others.
One of the most significant pieces of evidence for the Big Bang Theory is the cosmic microwave background radiation. This is a faint glow of microwave radiation that permeates the universe and is a remnant of the Big Bang.
According to the most recent measurements, the universe is estimated to be around 13.8 billion years old. This age is determined by studying the cosmic microwave background and the expansion rate of the universe.
The Big Bang Theory suggests that the universe is constantly expanding. This expansion was initially discovered by astronomer Edwin Hubble, and it's still ongoing today.
The theory posits that the universe began as a singularity, a point of infinite density and temperature, where the laws of physics break down. The concept of the singularity is a challenge to our understanding of the universe.
The Big Bang Theory provides an explanation for the formation of the light elements, such as hydrogen and helium, in the early universe. Heavier elements, like carbon and oxygen, formed later in the cores of stars.
The Big Bang Theory doesn't account for everything in the universe. It's believed that dark matter and dark energy, which make up most of the universe, play crucial roles in its evolution. However, we still know very little about these mysterious substances.
