What Came Before the Big Bang? The Science of the Big Bounce

Is the Universe on an Infinite Loop? Cyclic Cosmology Explained
Description: Is time a straight line or an endless circle?
We’re exploring Cyclic Universe models, where our cosmos is just one "aeon" in an infinite chain of successions. This isn't just science fiction—it's based on cutting-edge research in string theory and quantum gravity.
Key Topics Covered:
Colliding Branes: The original "Ekpyrotic" theory where our universe was born from the collision of two three-dimensional worlds in a higher-dimensional space.
Conformal Cyclic Cosmology (CCC): Roger Penrose’s mind-bending theory where the "infinitely big" end of one universe becomes the "infinitely small" beginning of the next.
Instant Folded Strings (IFS): The newest discovery in cyclic models—unusual strings that violate energy conditions to trigger a smooth bounce.
The Fate of Black Holes: What happens to the massive black holes of our universe when the next cycle begins?
The End of Inflation: Why some scientists argue that a "Big Bounce" is more likely than the traditional theory of rapid cosmic inflation.
