My point of view is that when you want to study the laws of physics it is important to study the evolution of the Universe completley independent of any human influence. In fact you should study the evolution from all points in the Universe simultaneous. Not from the view point of a single human being, not from humans on earth, not from the solar system, but globally. In fact you should study with your eyes closed.
Ofcourse you need observations, the more the better, but if you want to unravel the laws of nature you should start from one coordinate system (which evolves in time) and the first step when you have to collect new observations should be to place these local observations in the global coordinate system. This picture from the local group: Wiki: Local Group shows this image at one instant t. This image changes continuously. However each star is not a visible object but much a black hole i.e. something invisible. This is a difficult step.
The point is that working from within this coordinate system is much simpler because light is not more an issue, which (when used) introduces all sorts of physical problems. For example (the behaviour) light is influenced by matter i.e. gravitation and as such the speed of light is not constant and its path is not a straight line.
The speed of light is still an issue when clocks are used, specific when moving clocks are used (in this case I mean clocks which inner workings is based on light signals) because the behaviour of these clock is affected by the direction and the speed of light. As such moving clocks ticks slower compared with clocks at rest. The solution is that inside your coordinate system there are no moving clocks.
The advantage of using one coordinate (and in some sense banning all humans) has many advantages. The problem with "Schrödingers cat" disappears because there is no observer any more to look inside the box. In fact the state of the cat is completely defined if there was a radio active decay "Yes" or "No". That means the cat is either alive or dead, but never both (Ofcourse he can be dying). The challenge now becomes what causes this radio active decay and why is the half-live time different for certain elementary particles.
What also disappears is the uncertainty principle becauses that principle is very much related to out human incapabilities to meausure the true values of certain parameters. In fact each photon has a specific value (position) in space. The problem is to know this position at a certain instance t. The issue is when you measure its position you destroy the photon making it impossible to know its position twice and to calculate its speed.
