comment Why does matter exist in 3 states (liquids, solid, gas)?
Actually, so far as our ability to measure and interpret are concerned, the ultimate answer to a "why" physics question is "energy". I've also taught my daughters the corollary the ultimate answer to a "why" people question is "money".

comment Can radioactivity be slowed through time dilation?
Muon decay is the key to remembering so many concepts of special relativity. For instance, the alternative interpretation - that the distance from the top of the atmosphere to the ground is shorter - is how I remember when Lorentz contraction occurs.

comment Cause for spikes in trinity bomb test
I find this answer to be very valuable: it demonstrates the method used to get to the answer, not just the answer itself. Which is more valuable? I value the method.

I find that dupes are like symlinks. I often get to the good stuff by googling the dupes!

comment If gravity isn't a force, then why do we learn in school that it is?
Though I agree that this is a physics education question, not a physics question, it implies a greater "Why is physics traditionally taught this way" question that is pertinent to both physicists and those learning physics. So pertinent, and in fact fundamental, that I consider this to be one of the best questions to be asked on this site.

comment Push a Boeing 737 on ice: Did this guy have a chance?
@MooingDuck: That is because I ask if the worker can prevent the plane from sliding further, i.e. when it stops between slides. In the beginning of the video, it can be seen that the plane slides a bit, then stops, before it starts to slide again.
