In the 20th century, scientists made significant breakthroughs in our understanding of the universe, including the discovery of cosmic background radiation, the Big Bang theory, and the accelerating expansion of the universe.

The Big Bang Theory

The Big Bang theory is the most widely accepted explanation for the origin of the universe. According to this theory, the universe was formed about 13.8 billion years ago in a massive explosion. The universe was initially hot and dense, and it rapidly expanded and cooled, leading to the formation of matter and energy.

Cosmic Background Radiation

In the 1960s, Arno Penzias and Robert Wilson discovered cosmic microwave background radiation. This radiation is believed to be the leftover heat from the Big Bang. It is one of the most significant pieces of evidence for the Big Bang theory.

The Accelerating Expansion of the Universe

In the late 1990s, astronomers discovered that the universe is expanding at an accelerating rate. This discovery led to the theory of dark energy, which is believed to be the force behind the accelerating expansion.
