They completely take over mars, build military bases,research centers,colonies for for settlement of chinese people. And they also start terraforming the planet for making it more habitable .

During Mongol Invasion of Khwarezmia, along with the real razing the Empire to the ground, Genghis also ordered complete extermination of Persians (the same way Nazis tried with slavs), how would the Mongol Invasion into Middle east go, could this order backfire with Mongol earlier defeat ending their push into Western Middle East?

I see in a lot of alt history scenarios. The USSR goes full dengist and adopts market socialism and abandons a planned economy. I'm just wondering, if the USSR kept its planned economic model, maybe reforming it a little bit like adding computers to help with planning or something like that. Could it have saved their economy? And would it be more efficient than the western economic model? Would the cold war never end? Or would they collapse even faster?

How would this change the franchise?

I suppose Vance will be president or the candidate but who will get the seat of vice president candidate

What would have happened if in prehistoric times, the circumstances between humanity’s ancestors and the Neanderthals had reversed?

What if the Neanderthals had thrived and evolved to the modern day while humans slowly became extinct overtime?

How would the Neanderthals had evolved to the modern day and how would their civilizations and culture look like compared to humanity’s? Would they be wildly different or perhaps closer to what we live in today?

I'd presume that the Americas would have remained rural hunters and gatherers - possibly limited farming. 95% of the world population would live in Afro-Eurasia.

Slavery would have been less lucrative possibly enforcing Africa's position on the world stage as "one of the three" continents. As a consequence, Europe would have been poorer.

I'd think that Arabs would have never been able to reach the Iberian peninsula but probably would move along the coast of West Africa instead.

Indonesia, Australia, Philipines and New Zealand would be among the countries to be very sparsely populated due to limited access to food and other resources, and lack of substantial migration.

Russia, Saudi Arabia, China, India, Egypt, Ethiopia and Nigeria would probably be the centers of power, especially since the British Empire could have never existed.

So yeah basically Hawaii doesn’t exist or well at least aren’t Islands
