If you've seen the film, 'The Dam Busters', you will know that an explosion underground, or under the water against the dam walls, has a much greater destructive capacity than an explosion in air in which the blast dissipates into the air.. Quoting: Anonymous Coward 369375
This is not always true. A dam primarily made of earth is hard to destroy by using classic explosives because earth has elasticity that makes the dam returned to original form after explosion passes. Also, earth and water itself absorb the shock to some extent. I think the best spot to destroy a dam is rather a gate when the dam is holding water.
Anyway, the great enemy, if not greatest, to a dam is “overtopping water”. Most structural failure is related to water in one way or the other. A Dam is not an exception. So, a big flood is more dangerous than a big bomb as is the natural force more powerful than any man-made.
An explosion underground between Switzerland and France could really crack the European continent and cause that land to sink, as has been foretold by Edgar Cayce and Gordon Michael Scallion. Bye bye Europe and all or most of the people who live there, because Europe is predicted to become islands. Quoting: Anonymous Coward 369375
If any consequences from CERN’s experiment follows the conservation of energy that most, if not all, physics laws are fundamentally based upon, then this kind of disaster will not likely occur. However, my concern is if they really find a micro black hole or the like and a genius way to stabilize it, then it can become a potential weapon, a cleanest “atomic bomb” that can penetrate anything.
In this regard, I have a question to OP. How is the security level of CERN? Is it a university- or research-level security with locks and ID cards, etc., or a military-level security with armed guards, etc.? This may hint us what they are really up to.
