Ok.
So I have seen threads that enquire.
1)What if the Internal Combustion engine was never invented.
2)What if man went steampunk .
3)Dieselpunk AHC
4)What if Zepplins were invented in the 1870s
Or threads like
1)How would science be different if Germany never unified.
The OP are always excited. The first few people provide satisfactory answers.
But then some experienced science oriented alt historian comes and proves that inventions like the Internal Combustion engine were all but invietable or that there is a 85% chance of Steampunk never being possible due to science related factors. Or that people in the 1870s simply didn't have the knowledge to make the strong cloth to make Zepplins that people in 1910 had !
So here is my question .
In A timeframe from 1810-1910, which alternate inventions can be made or can not be made(Luke for ex no steamengines) or which alternate path can science take due to political and economic factors(Like no German unification) that can massively or slightly effect Human history, the history of war and anything else and most importantly.................
Like I said above, the answers should be very very possible and even science oriented alt historians must at least partially approve of them.
Notice: No penicillin answers wanted. I know that already.
THANK You.
