The statement that the universe was created by light might be a reference to certain religious or philosophical beliefs, but it does not align with the current scientific understanding of the origins of the universe. In scientific terms, the universe is believed to have originated from an event called the Big Bang.
According to the Big Bang theory, the universe began as an extremely hot and dense singularity around 13.8 billion years ago. At this initial moment, the universe was in a state of extreme energy and temperature. As the universe expanded and cooled, various particles and forces emerged.
Light, in the form of electromagnetic radiation, is indeed a fundamental aspect of the universe and plays a crucial role in its development. However, it is not the direct cause of the universe's creation. Instead, light is one of the forms of energy and information that emerged after the initial stages of the Big Bang.
In the early stages of the universe's expansion, the energy was in the form of extremely high-energy particles. As the universe cooled further, around 380,000 years after the Big Bang, electrons and protons combined to form neutral atoms, allowing light to travel freely through space. This event is known as cosmic recombination and is often referred to as the "last scattering surface." The released light from this period is what we detect today as the cosmic microwave background radiation, a remnant from the early universe.
It's important to distinguish between scientific explanations of the origins of the universe and mythological or metaphorical interpretations. Scientific explanations rely on empirical evidence, observations, and rigorous testing, while religious or philosophical beliefs often incorporate different narratives and interpretations that may not align with scientific understanding.
