How big is the initial size of the Big Bang... inside a Planck length? Can it fit inside? Or as big as an egg? Or a kilometer?
The initial size of the Big Bang is believed to be incredibly small, about the size of a single atom. This is based on the theory of cosmic inflation, which suggests that the universe underwent a rapid expansion in the first fractions of a second after the Big Bang.
Scientists use a variety of methods to estimate the initial size of the Big Bang, including observations of the cosmic microwave background radiation, measurements of the expansion rate of the universe, and theoretical models based on the laws of physics.
While there is strong evidence to support the theory of cosmic inflation and the idea of an incredibly small initial size, it is not yet confirmed by direct evidence. Scientists continue to study and gather data to better understand the early moments of the universe.
The initial size of the Big Bang is vastly different from the current size of the observable universe. The universe has been expanding and cooling since the Big Bang, and today it is estimated to have a diameter of about 93 billion light years.
Due to the complex and dynamic nature of the universe, it is unlikely that we will ever know the initial size of the Big Bang with absolute certainty. However, ongoing research and advancements in technology may provide us with a better understanding of the early universe.
