Question: Which theory states that the universe is always expanding but its density continue to fall as is gets larger?
The theory that states that the universe is always expanding but its density continues to fall as it gets larger is the Big Bang theory. The Big Bang theory is the most widely accepted explanation for the origins and evolution of the universe. It proposes that the universe began as a hot, dense, and infinitely small point, known as a singularity, around 13.8 billion years ago. From this singularity, the universe expanded and cooled, and matter and energy began to condense into stars and galaxies.
The expansion of the universe is driven by a mysterious force called dark energy, which is thought to make up around 68% of the total mass-energy of the universe. As the universe expands, the density of matter and energy in it decreases. This is because the total amount of matter and energy in the universe is constant, but as the universe gets larger, it is spread out over a larger volume of space. This means that the density of matter and energy in the universe decreases as the universe gets larger.
The Big Bang theory is supported by several lines of evidence, including the cosmic microwave background radiation, the large-scale structure of the universe, and the observed abundance of light elements.
