Different humans ?

Hi All,

As I haven't done much science fiction speculation in a while:

In 500 years time, the teachers are still unwilling to open up schools, the press is still going on about Dominic Cummings, the church of England is trying to get rid of the Tory government and there are three types of humans. 

The first are what you could call the original humans, who are similar to 21st century ones, albeit with greater medical and pharmaceutical technology, maybe more liberal and urbane, but one which is broadly democratic and capitalist,  that gives a greater life expectancy (120). Examples of these humans would be Earthers (named after the home planet earth ) and their cousins of Alpha Centarui. 

The second group are the adapted humans. These are humans whose bodies have adapted to radically  different non earth environments. Examples include the Lunar nation of humans who colonised Earth's moon & the asteroid belt, whose bodies are now adapted to live in low to zero gravity environments. They're humans, but much thinner and taller,  whose physiology means they cannot live on earth without either an exosuit,  or if exposed without one , ventilators or wheelchairs, due to the earth having higher gravity. Another example on the opposite  would be humans from Kelper whose gravity is so much higher than earth, they are very short, but have super human strength in an earth like gravity.

The third group are the trans- humans, who deliberately altered themselves to , as they see it,  be better. They are divided into two sub groups, themselves as diverse in culture as any of the first two, but these categories  do  demonstrate how they changed themselves, with each claiming their way is the better one.

The one group uses robotics and synthetic skins . The other use eugenics, cloning and genetics to , as they see it, progress the human race.  They are called trans humans and not transformed humans, because their societies are constantly splitting between those who want to go "one step further" and those who don't.  Thus they are constantly in the process of transforming at whatever limits that current science might put upon their upgrades and genetics.

Thankfully the universe is so huge  ( The earth has a diameter of 7,909 miles, one light year is 5900 trillion miles and the  nearest star is over 3 light years away, the milky way galaxy itself is over 700,000  trillion miles in diameter) there's enough space for these groups to get along peacefully, albeit in a political/philosophy/ culture wars way (c.f. the Anglican Bishop of Venus controversy). Indeed the universe is maybe, according to one wag  "one giant middle class liberal capitalistic-democratic estate", rather than a political situation wherein there is the constant threat of warfare. True there's the odd border , colonial or bushfire war and pirates can be a pain ,but nothing in terms of massive interstellar conflict. No one can really be arsed. Especially when there's money to be made...
