Each time a choice, create the universe with their eighth choice, whose lives may be very different. This raises a number of moral issues, on others for what we can "afford" to thank the dead hope.
This is reminiscent of a febrile imagination of the philosopher who is born of the concept, but many physicists believe that the multiverse is real. And they rely on the evidence - that's four ways multiverse may occur in our everyday world.
Wave function
The mathematical description of any entity of quantum properties of the system. Such features - for example, the atomic spin direction - at the same time can have several meanings, that is, to be in quantum superposition. But just such a characteristic measured at getting a single value - the spin, this may be up or down.
According to the traditional Copenhagen interpretation of quantum mechanics interpretation, saying that the wave function, as measured "collapsed", but it is not clear how this happens. (This is illustrated by the famous dead than alive than before watched a box, Schrödinger's cat experiment by heart.) Multiverse wave function never collapsed: it describes the feature in all universes. The spin of an atom in this universe is up next - down.
Wave particle duality
The famous experiment, one photon sent towards a pair of slits with their name on the phosphorescent screen. Measurements of any slot to record the individual photons, moves through one or the other slot. But without measurement, an interference pattern is formed on the screen, as if each photon to get through both holes at the same time and both difragavęs as a classical wave.
This duality of quantum mechanics called the core mystery. According to the Copenhagen interpretation, so going on a wave function collapse. Undisturbed each photon through both slots aparatura http://www.autonata.lt/ Autotrade simultaneously: measurement slot makes it a "choice." Meanwhile, the interpretation of the interference pattern formation in many worlds, each photon passes through only one slot. - An interference pattern is formed when a photon interacts his clone, flying through another opening in the parallel universe.
Quantum computers
While quantum computers still infancy, in theory, they are incredibly powerful, able to solve complex problems much faster than any conventional computer. According to the Copenhagen interpretation, this is because the computer operates tied qubits "which could take many more states than the two states, available in classic computer bits. According to the multiverse interpretation of this is because they perform the necessary calculations of the number of times the universe.
Quantum Russian Roulette
This is equivalent to Schrödinger's cat role. You will need a gun, which controls the operation of the quantum properties of, say, the spin of an atom, which can be measured in two possible states. If the Copenhagen interpretation of the right is already heard 50-50 chance of survival. The more "play", the less likely it is to survive.
On the other hand, if the true multiverse, there will always be a universe where "you" live, no matter how long you play. In addition, it can always be placed on the elevated "observer" status kavnt mechanics. Just hear a series of clicks, because not every rifle shot - in the immortal and comprehend. But caution: Even if you have a gun quantum physicists argue long as the inerrant experiment a success.
