In this famous thought experiment a cat is placed a sealed box. A random event at the quantum level has a one out of two chance of triggering a lethal mechanism.

The outcome of this event is unknown until an observation is made. According to the principle of superposition of states, the cat exists in a state that is both dead and alive until an observer opens the box.

The construction of the RMS Titanic represented the culmination of the industrial revolution. It was the largest man-made moving object at the time. To this day it had the largest reciprocating engines ever built.

The industrial revolution also begot air pollution eventually resulting in global warming. Today this is causing the melting of the ice caps and producing glaciers.

So there is a cruel irony in the fate of the RMS Titanic which struck an iceberg on April 14, 1912. Was this a prophetic warning that the earth could suffer the same fate?

    If an infinite number of random universes exist (or will exist) will our present universe repeat itself an infinite number of times?

Superstring theory can be used to describe our 4d universe (three dimensions plus time) as existing on a brane inside a higher dimension space called the bulk. Our universe is just one of an infinite number of bubbles in the 11 dimensional bulk. The collision of 2 bubbles resulted in the big bang and the creation of the universe.

So there must be an exact duplicate of you in another universe and an infinite number of permutations of you.
