You know what would be awesome?
If someone on the Internet created a website that displayed all historical events of the world on one scale
Oftentimes we will read about happenings in one section of the world, but not in others
Even more frequently, events that occur simultaneously are written about as if they occurred in completely alternate timelines.
So,
create a website that incorporates everything we know about history everywhere. Make it explorable, so you can find something interesting and follow it through the years, or look at everything else that was happening around that same timeframe
It would be complicated as fuck to make, and would be a shit-long process IN the making
but Fuck
Can you imagine?...
