The Big Bang Is Responsible For Creating The Early Universe

The Big Bang describes a sequence of events responsible for creating the early universe, which over billions of years progressed into the universe as we know it today. Through observable modern science, we are able to offer strong proof for its occurrence. This includes the movement of galaxies, the expansion of space-time, and the presence of hydrogen atoms and photons in the universe. While each of these pieces of evidence do not provide fully convincing arguments when viewed individually, they logically complement each other in a way that, as a whole, points to the Big Bang as a necessary event.

The billions of galaxies in the universe appear to be uniformly scattered in every direction throughout it. The far-away galaxies are seemingly becoming more distant from Earth.

For example, a star viewed from Earth may appear to be in a different location than its true position because of the Sun’s gravity bending space-time. In addition to bending, space-time can stretch, which causes two objects in space moving away from each other. To understand the significance of this as proof for the Big Bang, it is essential to realize that expanding space-time affects the movements of galaxies. It causes the wavelength of photons to be stretched, and is responsible for the visible red-shift in a distant galaxy appearing much greater than what would be expected based solely on the galaxy’s movement itself. It makes sense that the photons emitted from a far-away galaxy would be more red-shifted than a closer galaxy, as the greater distance of the far galaxy from us allows more time for the photons to be stretched before they are viewed in a spectrometer on Earth. The Big Bang provides a singular explanation for the beginning of the universe and why it has been constantly expanding since. It initiated the space-time expansion responsible for the locations and movements of galaxies, as well as how we perceive this movement from
