Final answer:
The Big Bang led to the origin of both space and time. It was not a localized explosion in space, but a rapid expansion of space itself.
Step-by-step explanation:
The Big Bang was not a localized explosion in space, but a rapid expansion of space itself. This means that both space and time originated with the Big Bang. Before the Big Bang, there was no space or time as we know it.
The explosion of space (and time and matter and energy) happened everywhere in the universe and led to the creation of all matter and energy that exist today. It is important to note that the Big Bang is an ongoing process; we are still in the midst of it.
