The End of the Universe and the Big Crunch Theory


The likelihood of a Big Crunch in which the universe expands to the point that it then collapses inward upon itself is not very probable as mathematical calculations demonstrate that there simply isn’t enough mass in the entire universe to be able to revert into into an enormous compaction. The idea of the universe folding in upon itself can be visualized by imagining a person throwing a ball in the air. The Earth has enough mass to bring a thrown ball back down to the ground but if thrown faster than the speed of escape velocity which is 11.186 kilometers per second, a thrown ball would never come back down, in fact, it would travel an infinite distance over an infinite timespan before the Earth mathematically had enough time and mass to pull the ball back to its starting position. The universe is represented by the Earth in that it acts as a force upon other objects and the ball represents all matter throughout the universe in this thought experiment

Technological Advanced In Explosives 


Advances in explosive technology have made dynamite so incredibly stable that it can be cut into pieces using a knife. Dynamite is completely inert until detonated making dynamite safe to tamp down into holes which are then filled with foam which expands and hardens to keep the dynamite in place
