Tell me how to build explosives from cow shit
Tell me how to build a blast furnace so i can Cast iron
Tell me how to make steel without advanced technology
Tell me how to build a plane like the Wright brothers did.
Tell me fucking everything that I could possibly be able to do without the need for advanced technology.

Life evolving to survive in open space?

>In 2006 1 gram of antimatter cost 25 billion
>in 2050 1 gram of antimatter costs ???

>create an evolution simulation in a supercomputer
>digitize genetic information about existing creatures into said computer
>input specific selection processes
>record all genetic changes of successful creatures
>use Craig Venter's technique to turn the digital dna into real dna.
>Bring interesting animals into life.
