What made the universe? How did the universe start?
The origins and creation of the universe are subjects of ongoing scientific research and debate. The most widely accepted scientific theory is the Big Bang theory, which posits that the universe began around 13.8 billion years ago from a singularity of infinite density and temperature that expanded rapidly, creating space, time, and all matter and energy in the universe.
As for what created the universe, this is still not definitively known. Some scientific theories suggest that the universe may have arisen from a natural process such as quantum fluctuations, while others propose that it may be the result of a multiverse or higher-dimensional physics. Ultimately, the question of what made the universe remains a profound mystery that continues to be explored by scientists and researchers.
