So it doesn't give you godmode:

/c game.player.character.destructible = false

And why is it 1 red science when it could be

unit =
{
  count = 1,
  ingredients = {},
  time = 1
},

... free?

No, but if you get hit by 20 trains in a row, or eaten by a million biters, maybe you deserve to die, who says go isnt unkillable :D
As for your actual questions. Its because i just made a quick mod for myself, and since i couldnt find anything similar, i uploaded it too. Didnt know there was a console command(?) i couldd just have used.
Its the first time i tried to make a mod, and i just copied parts of one that added some researches, so that was the quickest way for me.
