Explanation:
Big Bang Theory
The Big Bang is the singular cataclysmic event that started it all: the instant 13.8 billion years ago that marked the fiery birth of the universe. No one was there to bear witness, of course, but physicists and astronomers are confident that the Big Bang theory — or model, as they often call it — provides an accurate picture of how the cosmos came into existence.
What proof is there that the Big Bang actually happened?
Several lines of evidence that strongly support the Big Bang model. One involves the relative abundance of the chemical elements that make up the stars and galaxies; the amount of hydrogen, helium, and heavier elements that we observe is just what the theory predicts.
The observed speeding away of distant galaxies is another clue, as is the existence of the CMB. More recently, scientists using orbiting telescopes like the Wilkinson Microwave Anisotropy Probe and the Planck observatory have measured the CMB in fine detail — and its characteristics are consistent with the theory.
Answer:
★The big bang theory actually says that earlier, at first there was no planets except a big ball like thing. After a huge amount of time,millions of years later, due to some collisions the big ball blasted to form all these planets and other things that are found in the universe and also adds that after some years all these planets will again join together to form a ball.
