Schrödinger's cat

As being a feline lover myself. I thought that my first post should be about cats.
Well, the internet is full of cats, cats and cats. Similarly one of my favorite cat is Schrödinger's cat. You probably might have heard about this particular kitty (presumably belonging to Erwin Schrödinger) who is dead as well as alive.... confused that how can it be dead or alive at the same time? Well don't be. Its pretty simple.


You first put a kitty in the bunker. Make sure its alive. Now rig the bunker with these:

1. Lots of gunpowder
2. A Geiger–Müller tube
3. A hammer
4. A teeny-tiny radioactive source, so small that in a course of an hour just one atom decays.
5. A spark plug

Note, keep all these away from the arm's reach of the kitty. Point the GM tube towards the source and connect it to the hammer. Once the tube detects a radiation (which is purely random) the circuit is closed and the hammer falls on the spark plug and hence igniting the gunpowder hence bye bye kitty.

Now after the setup, LEAVE!! the bunker (unless you want to go bye-bye). While out, immediately start your clocks and wait for certain amount of minutes (lets say 10). After 10 minutes open the bunker and see if the kitty is dead or alive. If you repeat this experiment enough times (with enough kitties), you would observe that there is a 50% chance where the kitty survives and 50% where the kitty goes bye-bye.

The Quantum mechanical interpretation or should I say the Copenhagen interpretation says that after a fixed time T. The cat goes into quantum superposition i.e. the cat is both alive and dead inside the box and an act of looking (or observing) forces nature's decision. Hence our curiosity kills the cat.
But what about the cats perspective?
Well, the cat either sees the gunpowder explode or doesn't see any such occurrence.
So, there are the following occurrences inside the bunker:

1. The powder explodes and the cat goes to cat heaven.
2. The powder doesn't explode and the cat lives.
3. There is no alternative such as the gunpowder explodes and the cat lives to tell the story.

Hence, the cats reality becomes entangled with the outcome of the experiment. And its our observation with the experiment that forces nature to collapse into one of the possible outcomes.

But, if you give a second thought to it, we are like the cat too. Either the cat dies and we see it dead or the cat lives and we see it alive.

So who is observing us, to force nature to collapse into one reality? Or do both possibilities happen in parallel multiverse ? This collapsing to one reality problem is one of the biggest un-answered questions in quantum physics.
