Alternate Stories are a page dedicated to saying stories of alternate things in the universe, like what if Milky Way and Andromeda never collide or what if Theia never collided with Earth.
What If Jupiter Never Existed[]
Ah Jupiter, the biggest planet in the Solar System, he has saved humans many times from being killed by asteroids, but what if, Jupiter never existed, what if his core failed to form and just became a bunch of planetoids instead?
Well its theorized that there were several planets in the early solar system near the Sun, but Jupiter destroyed them and caused them to form the inner planets today, now with Jupiter out of the picture these planets were never killed and continued to live in the Solar System, and Earth would never have formed and life wouldn’t exist in the solar system.
Also, Jupiter saved Earth many times from asteroid collision, because of Jupiter now gone asteroids colliding with planets like Earth in the Solar System would be much more common.
What if Earth and Theia Never collided[]
If Earth never collided with Theia, she would still exists. and the moon would have never formed.
But that is not the only thing that would have happned. if the moon never formed, earth's Magnetic field would shut down a few billion years earlier just like Mars because a lack of tidal effects keeping the core warm. if that happned, Earth would be devoid of Life and a cold radioactive dessert, Just like Mars
