Two galaxies collided causing an immense explosion as stars crashed into one another
|
|
|
All of what would become the universe was concentrated in a single small point, or singularity, which rapidly expanded into what is now stars, planets, galaxies, matter, and energy.

|
|
All matter emerged from a massive black hole at the center of the universe.
|
|
|
Parts of the sun were ripped off by massive internal explosions and were thrown into space where they cooled to become other things, like plants, comets, and other galaxies.

Detailed explanation-1: -The Short Answer: The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now-and it is still stretching!
Detailed explanation-2: -What evidence is there to support the Big Bang theory? Two major scientific discoveries provide strong support for the Big Bang theory: • Hubble’s discovery in the 1920s of a relationship between a galaxy’s distance from Earth and its speed; and • the discovery in the 1960s of cosmic microwave background radiation.
Detailed explanation-3: -The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
Detailed explanation-4: -Doppler Red-Shift Evidence The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
