I think that the scientists who make the Grand Hydrocolater are morrons. they can create to much materia in 1 sec wich will kill us or they will make black hole wich will eat us

Do you mean the Large Hadron Colider? (Grand Hydrocolater hahah). They cannot create too much matter in 1 sec, because the toal amount of matter produced must agree with E=MC^2 , so 14 TeV = approx 1.5x10^-4kg (0.15g)

I really enjoyed this, it's nice to see youtube is now posting longer videos. keep up the good work. food for thought: is space really that big or are we really much smaller then we give ourselves credit for?
