')Seems to me, without an observer there is no experiment or information.
Measurement problem in QM is a very well known issue.
Many brightest brains in physics have fallen badly while attempting to resolve it.
Basically we have Copenhagen and Multiverse interpretations. Also few other less popular proposals.
First is telling about wave function collapse upon interaction with mythical observer what results in
reality to exist.
This collapse is possible upon interaction with observer, though there are not yet successful attempts to demonstrate that any
macroscopic object can serve this end.
Second is insisting that Universe splits upon forcing a quantum system to make a choice into multitude of new Universes with each of them carrying a distinct possible outcome.
But before an act of observation is made a system really exist as a superposition of all possible outcomes.
This view fills our everyday life with half dead cats and partially pregnant women, so I personally prefer Copenhagen interpretation, which on the other hand is mathematically ugly due to arbitrary discontinuum.
There are no indications at all where is the truth.
It is possible to run famous Schrödinger cat experiment in real life these days, so you are free to find out which version is correct (if any).
If Multiverse explanation is true you will find yourself immortal to this experiment regardless of number of repetitions despite of your family in parallel Universes removing number of your bodies in outcomes where conclusion was "dead".
But for yourself and only for yourself you will know.
But if Copenhagen interpretation is correct then every attempt gives you a 50% chance of death. So surviving 30 gives you 1 in a billion chance.
There are some discussions, also by professionals and on the net, of this experiment.
