Meanwhile, the fired IT director denies misusing school computers
Why nobody was able to find any alien civilizations yet ?
That's because of a number of factors.
If present science are so sure about all possible consequences of creating black holes using Large Hadron Collider or any collider that size, than why any expirements needed ?
Because for a hypothesis to become a theory, it must be tested. That's how science works.
How people that are not "against science" can guarantee any HollyDolly mother, that she's childs are in safe place
There is no such thing as absolute safety. Your "1%" chance enormously overestimates the chances of a black hole swallowing the earth. We're not talking about a pea sized black hole (which would have a mass as great as a mountain), but an infinitessimal mass measuring the same as a few atoms, at most.
Information can enter black hole but can't escape.
See, the problem is calling these tiny singularities "black holes". Wikipedia's definition of "black holes" excludes these things. There is a vast difference between a gnat and an elephant, even though both are animals. There's no magic about black holes swallowing light; in space an object must have enough mass to collapse on itself to create a black hole, if I remember correctly it's about the mass of a thousand suns.
You have far more dangerous things to worry about, driving your kids to the store for instance.
You should never bet against anything in science at odds of more than about 10^12 to 1. -- Ernest Rutherford
