Puzzle #9
#9. What Physics explains the enormous disparity between the gravitational scale, and the typical mass scale of the elementary particles?
In other words, why is gravity so much weaker than the other forces, like electromagnetism? A magnet can pick up a paper clip even though the gravity of the whole Earth is pulling back on the other end!
According to one recent proposal, gravity is actually much stronger. It just seems weak because most of it is trapped in one of those extra dimensions. If its full force could be tapped using high-powered particle accelerators, it might be possible to create miniature Black Holes.
Though seemingly of interest to the solid waste disposal industry, the Black Holes would probably evaporate almost as soon as they were formed.
