When we say that nothing, not even light, can escape a black hole, does that just mean nothing that we currently know exists? is it concievable that something could have physical properties that would allow it to escape from the gravity of a black hole?

physicists say to laymen "observing a quantum particle causes the wave function to collapse" but what does this mean mathematically? what does a collapsed function look like compared to the original?

why is oil/coal nonrenewable? don't we have the technology to recreate the conditions (immense heat/temperature) under which they formed, and plenty of raw material?

Why is it that path difference due to reflection when light travels from a medium with low index of refraction (n) to a medium with a higher index of refraction is always exactly 180 degrees regardless of how much higher the 2nd n value is?
