Every cosmologist and astronomer agrees: our universe is 13.7 billion years. Using cutting edge technology, scientists are now able to take a snapshot of the universe only a heartbeat after birth.
Armed with hypersensitivity satellites, astronomers look back in time to the moment of creation, when all matter in the universe exploded into existence. This is where we discovered an unsolved mystery as old as time itself – if the universe was born, where did it come from? Meet leading scientists who have discovered what they believe that the origin of our universe, and a window in the time before time.
Big Bang theory holds that the universe was once packed tightly in a small and incredibly dense space, known as a “singularity”. That is, until about 13.7 billion years, when a huge explosion of energy and the pressure began to give rise to entire worlds, galaxies and interstellar particles that form the universe as we know it today.
However, what caused the big bang? The physicists are left scratching their heads to that question. Since the universe began in a level so small, the laws of relativity are not fully implemented. In contrast, quantum theory, which deals with the world outside the law and the very small strange, must also be convened.
Successfully answering the question of what existed before the Big Bang would be necessary to close the gap between the worlds so far incompatible with each other, relativism and quantum mechanics. But even though the bridge has not yet been built, theories abound.
“Our universe may have either come into existence or collided with another universe,” theoretical physicist Michio Kaku said scienceline.org. “Big Bangs happen all the time.”
