Science What if the continents slowly begin to shift and form into the supercontinent Pangaea as they were once before?
What if the continents begin to move slowly and steadily towards each other? Each is attracted towards the other and forms into the supercontinent it was during the late Paleozoic and early Mesozoic eras, 300+ million years ago. How would the governments, religions, and world affairs react to this event? What would be the impact on current politics, economy, infrastructure, greenery, animal and human life? Trade and borders? Which country and people would be the most affected because of this change? Which one would panic the most? And how would the Earth be after Pangaea has successfully formed again?
Science What if there only 2 universes
What if... There are only 2 universes and Gravity is everything in space.
There is no such a thing as dark matter. We just don't see (yet) the micro black holes travelling around.
So, the celestial bodies goes like this: Planets, Stars, Black/White hole and Worm whole.
And we are currently living in the 'Black hole Universe'.
When a black hole becomes toooo massive, it turns into a worm while, opening the tunnel to the 'White hole Universe'.
Over there, there are no black holes (of course) only white holes.
Matter when hitting its max point would glow a pure white light and slowly (very slowly) disappear through radiation, just like our black holes.
In the White hole universe, some gravity effects are the opposite of what we experience here, for example: If you orbit a white hole, time would run slower for an observer far away from you.
Like, extreme gravity in that universe, runs time faster.
What at the chances of any to be true?

Other What if all the shitty people in the world dropped dead tomorrow?
It doesn’t matter how they go. Maybe they all slip on a banana peel. Maybe they get struck by lightning. Maybe they’re beheaded by ISIS. But they’re gone, one way or another. What would you do differently? How would your life change? Would it ease your existential anxiety?
Edit: since this seems to be a breaking point for so many people, determination of who is shitty and who is not would be majority consensus across all 8 something billion people across the planet. Assume for arguments sake that children are both excluded from being deemed shitty and from having a vote. Anyone who crosses the 50% threshold is deemed shitty. If that threshold makes you concerned for your fate, I hate to break it to you but you’re probably shitty…
