The first, based on the equivalence principle of general relativity, leads to the No Drama scenario: Because Alice is in free fall as she crosses the horizon, and there is no difference between free fall and inertial motion, she shouldn't feel extreme effects of .. A concrete example is the recent firm claim of the discovery of the Higgs particle, a crucial, and until recently missing, part of the standard model of elementary particles. Since this conflicts with the rules governing mass and velocity, as I understand, I suggest that poor Mary's atoms begin to heat up and vibrate to the point that they disintegrate into more fundamental particles. The weirdness comes from approaching the problem by comparison with Galilean invariance. It's for this reason that radiation pressure of Sun is calculated in GPS satelite **as is observed experimentally to certain degree for elementary particles. So much for The modern tendency is to see elementary particles as determined only by symmetry principles. For individual particles almost to 1 part per million. We can't also talk about a position of a photon if its really high energy due to Uncertainty Principle. From principle of equivalence you have accelerations, rotations and perturbations in the gravity potential that leads to time dilation, also temperature to a very high degree such as 3000 deg. There are some apparent (and somewhat controversial) counter-examples: the cosmological constant problem is a much more severe 'fine-tuning' problem which may be explained anthropically rather than through more fundamental principles. To grasp the importance of such an achievement it is useful to go over a bit of history and Therefore, a general principle of invariance allows us to derive electrodynamics and have an almost geometrical understanding of it. K can produce large time-shifts. The Higgs boson plays a key role in the Standard Model: it is related to the unification of the electromagnetic and weak forces, explains the origin of elementary particle masses, and provides a weakly coupled way to . €�This principle is invariant for any kind of coordinates transformation (any kind of coordinate system) •This principle can be expressed also for non-mechanical systems (thermodynamic systems, electromagnetic fields, elementary particle fields). In Relativistic QMech (high speed elementary particles that is) one should not at all talk about the position of a photon.
