It is perfectly plausible that such an object can be created here on earth.Here's how:
As atom-smashers attempt to identify the constituents of an atom's nucleus by breaking it into finer and finer particles (the finer the particle, the more power is required, hence the need for bigger and mor powerful cyclotrons), extremely heavy,new elements are created which last but an instant, before dissipating. It is entirely possible that such collisions will produce an object of infinite density. It is also known as a BLACK HOLE. Physicists reassure us that if such a thing happens, it will be temporary--evaporate almost as soon as it is created because it is unstable.
Such reassurances do nothing to assuage my fears. WHAT IF THEY ARE WRONG? Maybe it won't evaporate. In theory its density could cause it to sink to the center of the earth, and rapidly devour the entire planet. This fear has been expoused by many leading scientists, but the research continues.
I expressed my fear to a leading physicist, and his reply was," That's what we are going to find out!"
Talk about arrogance and irresponsibility!!
If this happens, I won't be able to shoot my guns anymore!
