Everyone would be permaband.

What if all band users were unbanned and everyone else banned?

minecraft-physics:

The forums would be filled with CatAnimations and PacBrads going LALALALALA DOOOOOOOOOOOO LOL69 pu$$ysl3yr69

 

What if everyone's IQ was at least 161?

I suppose we would make advances in technology and science, except that if everyone already knows how, then we would create almost the same society. We would just have smarter people.

 

What if Earth was the only planet that existed?

Well... Lots more asteroids would hit Earth, since neighbouring planets (such as Jupiter) won't pull asteroids and comets towards them. And we would also be very lonely, but it wouldn't really matter since we would be dead from all the meteorites.

 

What if it does count as necro to post on a thread that noone has technically posted on for 1 year?

Then whoever does that will probably have their post hidden.
What if the TPT program disappeared, leaving only the forums?

The forums become filled with several thousand mods, resulting in multiple mods having the same content.

 

What if a neutron star collided with an antimatter neutron star?

A very big boom would occur, and the concequences to us would differ depending on how far the collision happened.

 

What if all forms of art (music, painting etc.) suddenly disappeared, without us having any memory of them?

All inspiration would be lost but atleast we don't have to listen to hidden subliminal messages in songs.

 

What if I were a transformer?
