Answer:
The universe is believed to have originated about 15 billion years ago as a dense, hot globule of gas expanding rapidly outward. At that time, the universe contained nothing but hydrogen and a small amount of helium. There were no stars and no planets. Most astronomers think that the Universe was formed during an event called the Big Bang - a giant explosion which occurred between 10 and 20 billion years ago. During the Big Bang, all of the space, time, matter, and energy in the Universe was created.
