This is nonsense. Spacetime is a concept intrinsic to both quantum field theory and general relativity, our best physical theories. Quantum fields are defined as a value for every point in spacetime. General relativity defines gravity as the curvature of spacetime. Show me a physical theory that makes the same predictions without spacetime, and you can probably win a Nobel prize.

Mountain is just excitement in heights field. There is no mountains: it just geometry, people just follows the shortest path. Heights field just warps space-time, mountain is just illusion. And other nonsense from «shutup and calculate» guys. Switch from the model (heights field) to the physics (stone) language, please.

  You are trying to sound smart, but your argument actually illustrates the point that "there is no mountains" pretty well... You think "stones" is the real physics, while quantum field theory (presumably what you mean by using the word field) is something silly scientists came up with (the shutup and calculate guys)!? This shows a high school understanding of physics... because if you want to be pedantic, yes, there's no mountain!! Our world is basically empty space, with lots and lots of tiny disturbances in the quantum fields (particles and virtual particles) being the only thing that we can consider to really exist when we look deep enough... a mountain is just an emergent property of the arrangement of those fields in this particular region. That's what physicists mean when they tell you you never really touch anything because the force of repulsion between the atoms in your hand and the atoms in other things is so strong the atoms remain at a considerable (in the quantum realm) distance. But you probably don't "believe" any of this, right?

    Field is a mathematical therm. You are talking about model. Look at hydrodynamic quantum analogs. You will see, that many quantum effects, maybe even all of them, can be explained by waves, in therms of Newtonian physics. For example, the double slit experiment can be explained by self-interference of then pilot wave. When I can see quantum effects with my own eyes, all this mumbo-yumbo about waves of probability, half-dead cats, space-time bending, etc. don't work on me anymore. It's like tales about 4 elephants when I see round Earth in a porthole.
