Question

Two reasons why scientists are not worried about the possibility of us accidentally creating an Earth-destroying black hole with one of our particle accelerators are:__1__and 2____.

1) a)our particle accelerators aren't powerful enough to create one

b) black holes can't be created from such small particles

c) quantum mechanics forbids it

2) a) even if one were formed, Hawking radiation would cause it to evaporate almost immediately

b)black holes can't exist in normal atmospheric conditions

c) only dying stars can form black holes

Explanation / Answer

1)

Energies involved in even the most energetic accelerators on earth is too small to create a Black hole. The most powerful accelerator on earth is LHC which involves an energy of about 7 TeV in colliding protons. For creating a black hole from the proton collision will require an energy of around 1060 times the present energy.

So, the correct option is (a).

2)

The second reason is that if the black holes are created in the collision of particles like protons, they would so tiny that they would evaporate by the Hawking radiation(the very concept of which is quite controversial these days).

So, the correct option is (a).
