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: 
**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.
Religion is not (usually) neutral in Science/Technology development, but different religions may have different effects, even for quite "similar" religions.

Christianity is often pointed out as a large hamper for everything "material", and that has surely been true throughout the Dark Ages.

Different "flavors" of Islam produced both [al-Khwarizmi](https://it.wikipedia.org/wiki/Muhammad_ibn_Musa_al-Khwarizmi), whose name is encoded in the word "algorithm" (reason is kind of funny: it seems a repeated phrase in medieval translations often explained a process starting with: "alkwrizmi says..." so the mathematician became synonym of process itself) and Caliph Umar who (legend narrates) ordered [destruction](https://en.wikipedia.org/wiki/Destruction_of_the_Library_of_Alexandria) of Alexandria Library saying: "If those books are in agreement with the Quran, we have no need of them; and if these are opposed to the Quran, destroy them."

Ancient polytheisms never were a stop for scientific development, neither in Greece nor in India.

While certain (specific!) flavors of monotheism can be blamed to have been a brake on scientific advance and technology (mainly insisting on importance of afterlife) it is unproven atheism is of any help.
