The universe is still expanding today, and getting colder as well.Īs a whole, the universe is growing and the temperature is falling as time passes. It was Georges who first noted (in 1927) that an expanding universe could be traced back in time to an originating single point. This started the formation of atoms, which eventually led to the formation of stars and galaxies. Then about 13.8 billion years ago, space expanded very quickly (thus the name 'Big Bang'). Īccording to the theory the universe began as a very hot, small, and dense superforce (the mix of the four fundamental forces), with no stars, atoms, form, or structure (called a ' singularity'). The most commonly considered alternatives are called the Steady State theory and Plasma cosmology, according to both of which the universe has no beginning or end. The Big Bang is the name that scientists use for the most common theory of the universe, from the very early stages to the present day. The Big Bang is a scientific theory about how the universe started, and then made the stars and galaxies we see today.

The theory suggests that redshift proves the universe is expanding.
