But a meter is defined as the distance light travels in the time it takes an atom of caesium-133 to vibrate 9,192,631,770 times (which is the definition of a second), /> Since the frequency of the hyperfine transition in caesium depends on the energy difference of two levels in the atom, when energy rescales, the frequency also rescales, and with it, the definitions of the second and of the meter. The trouble with this is that this amounts merely to a rescaling of the units, not a rescaling of time or distance in themselves./Time is what clocks measure, and clocks operate according to physicalprinciples, and so does your brain, so if physical principles changeto make the clock run a different speed your brain will run at adifferent speed too and thus you'll notice no difference/> A change of units does not change the physics; dimensionless constants, on which everything depends,/There aren't a lot of dimensionless pure number fundamental physicalconstants, probably the most important is the fine structure constant,it's a pure number and determines, among other things, how fast thecesium atom and all atoms vibrate, that's how it got its name, itdetermines the fine structure of the spectrum the light that atomsgive off. The is approximately value of the fine structure constant is1/137, the exact value is e^2/(4*π*eo*h*c) where e is the charge of anelectron, eo is the electric constant, h is Planck's Constant dividedby 2π, and c is the speed of light. So when you do an experiment todetermine its value today after the split you will get a pure numbervery close to 1/137, the same number you got yesterday before the split.

`The question was whether it was observable if the energy were`

`apportioned in the split. The answer must make some assumption about`

`what other values are not-apportioned. One would be that all the`

`dimensionless constants stay the same...which implies the change is`

`unobservable. But that's not the same as saying energy is apportioned`

`because it is preserved across the MW total. Supposedly energy is`

`singled out as apportioned because it's nominally conserved. But it's`

`conserved because Hamiltonians are time-translation invariant.`

`Measurement in a branch isn't evolved by a time-translation invariant`

`Hamiltonian. So there's no reason to think energy is conserved. In`

`fact if it is always conserved that would be contrary to MWI.`
