Failures on deriving the Lorentz factor: using light clocks to calculate the dilation on space and time

Your calculations assume that the observers agree on the length of Alice's clock. For the vertical clock, that's the right assumption. Here is why: Alice can put little dabs of paint on the top and ...

Does time always dilate?

Time dilation describes how fast do you see a clock ticking that moves at v, it is not about time measured between two arbitrary events. In your second scenario there is no clock moving at v from A to ...

Time function as a function of energy (from velocity and gravity)?

Since you prefer a formula based on energy, the appropriate place to start would be the weak-field metric. Not all spacetimes have a notion of gravitational potential energy, but the weak-field metric ...
