What is the origin of the world?

Answer 1

There are two approaches.

One is to assume, or have faith in, an intelligent external force. Someone or something powerful enough to manipulate matter and cause our planet, other planets, our sun, other stars to all come into existence. This is a religious approach, and there are many different stories. The Judeo-Christian belief is that one god created everything that we know in 6 days of work. In other words, creation by God's powers.

The other approach is the scientific one, which currently holds that the Earth, all the other planets, the sun and all stars and galaxies are formed of material from space. The material itself was a product of a creation event called "The Big Bang" when a single source of matter exploded and created huge gas and dust clouds which under gravity came together and formed planets and stars and galaxies.

Answer 2

There is none.

This is a common misconception about the Big Bang -- that it consisted of a large explosion of mass into empty space.

It was, instead, an expansion of space itself, taking matter with it. There is no center point for this; all points in our Universe were equally close to each other during the start of the Big Bang.

The best analogy (for me) is to think of a balloon, with ink spots on it, expanding into the air. Imagine that the surface of the balloon is the entire Universe, with nothing "outside" that surface. As you can see, even as the ink spots get further and further away from each other, no point on the balloon can be called the "center" of the expansion.

Two problems with this analogy are that a balloon's surface is a curved 2-D object, and our Universe is 3-D and flat.

Answer 3

The origin of the world is believed to have started with the Big Bang, a cosmological event that occurred approximately 13.8 billion years ago. This event led to the expansion of the universe and the formation of stars, galaxies, and planets, including Earth.
