Question: One of the main themes of my series is an infinite multiverse, and one of the main characters was born on an earth where religion never existed. The humans of this world except for my MC do not and can not feel anger or hate. They can feel frustrated but not anger or any emotion like it. 

So I've been having trouble. How fast would a society advance in technology and medicine? Would it be too much of a stretch if they progressed every century or so? These humans in my story are not like most, they and the humans in a universe next to them(that being us) are the genetic descendants of twin gods that gave up their physical bodies to create a breed of humans who would one day receive a gift from beings that are known for being the most powerful in the known multiverse. A gift that would hasten and vastly improve their evolution. 

I know how advanced they are in the MC's lifetime. 
the year on his earth is 1954(I picked this year because of it being an alternate earth where Alan Turing is alive and the current president of the U.N.A), his America is known as the United Nations of America. There is no poverty, diseases, crime, and the most of the time the only reason people die is that they died of old age, which is around 200 to 400 years. Also, most of the planets in their solar system have been terraformed. In 15 years they will discover interstellar travel.

I'd appreciate any help given. :D

Answer: 
Counter-intuitively, Technology would advance more slowly
---------------------------------------------------------

As it would happen, Religion and War are some of the most powerful forces contributing to human technological advancement. For instance, Egyptian and Mesopotamian religion where some of the earliest contributors to architecture in the form of the Pyramids and Ziggurats. Egyptian religion also gave us the first Semitic scripts, which evolved into Arabic, Greek, Hebrew, Latin, etc. Hinduism, Jainism, and Buddhism where collectively responsible for the spark of the Golden age of India, which gave the world, among other things, the incorrectly named arabic numerals, damascus steel, and surgical tools. The Islamic golden age gave us algebra, public hospitals, and some of the earliest pharmacies.

War, I would argue, has had the greatest influence on Human technological advancement. Period. War gave humanity some of the first logistics system, advancements in metallurgy, chemistry, physics, epidemiology, it gave us the radio, microwaves, synthetic rubber, blood banks, plastic surgery, nuclear power, ultrasounds, rocketry, the internet. The fastest periods of advancement in human history come either during, or soon after war. Governments are willing to alter their entire economies to produce weapons of war and fund their research, without war, an incentive its equal does not exist. ***Without conflict, Solutions are not Needed***
**Born of religion**

Religion is mostly intertwined with our capacity of understand the things that are around us. Some believe that is genetic, causality or even a trait that affect some people more than others (God gene).

**Science**

Fire, dying, lighting, the sun, and most things that happend all around can't be simply explained, but still the humand mind try to give it a meaning to avoid "the fear of the unknown" in that regard we created explanations to handle this concepts. 

In other words science and religion are born for the same capacity of understand the causality of our actions and of most things around us, and the need to feel comfortable and safe within our world.

Which means that with enough intelligence, curiosity and necessity, religion and science would occur naturally. 

**Medicine**

In a world where you don't have diseases, gunshots, wars, hunger or epidemics probably the evolution of medicine would being halted mostly completly. There is no need of doctors or research if people don't fall ill.
