Yeah, seems light has such property, electron also behave the same. But I personally believe there is some flaws in our current understanding, just like both Relativity Theory and Quantium Mechanics can only describe part of our universe and they are both completly
different concept. (And Relative Time? that's just doesn't make sense. Time doesn't exist.)
It doesn't make sense to say "It depends" on facts and math. We currently say "it depends" because we are yet to find a better explaination to our universe.
"It doesn't make sense..."
This is a big problem for people trying to understand Quantum Physics, it just does not make sense unless you have walked all the way through it from where we were with classical physics and it's problems to where we are now. Most people have issues when
you say observing something will cause the probability function to collapse at which point the object becomes defined.
And your right, the theory is not perfect, may people have issue with the standard model for particle physics because of pesky little things like renormalization and the fact it relies on real world numbers that can only be measured through experimentation
and cannot be calculated by theory alone. But this is what science is all about, you fit a theory to the available data and the becomes the current state of the art until someone comes up with a better idea that explains and unifies a bit more of the world,
or someone proves you wrong! This is why the search for the Higgs particle is important, why people are sinking billions into massive pure science experiments, the current theory predicts it exists, if it is found at the expected energy range, it’s one more
tick that we are going in the right direction with all this.
