! Theory !! Driver !! Outcome
|-
| The Big Freeze || Dark Energy || The universe expands forever until every star dies and atoms pull apart.
|-
| The Big Rip || Accelerating Expansion || Dark Energy gets so strong it rips galaxies, stars, and even atoms apart.
|-
| The Big Crunch || Gravity || The expansion stops and the universe collapses back into a singularity (The 'Big Bounce').

'''The Concept of "Cosmological Redshift"''': This is not like a siren passing you (Doppler Effect). It is the '''space itself''' stretching. As light travels through the growing universe, the waves are stretched out. Analyzing this light is how we can "look back in time"—the farther we look, the further into the past we see.
