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: -The cosmic microwave background radiation (CMBR) that Penzias and Wilson observed is leftover heat radiation from the Big Bang. Today, CMBR is very cold due to expansion and cooling of the Universe.
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: -Approximately 13.7 billion years ago, all the matter and energy in the universe were created in an enormous explosion known as the “Big Bang”. The universe expanded and cooled and is still doing so today-evidence Doppler Red-shift.
