Equation 97 · Part 1 · The Clock That Comes Back Wrong by Exactly Its Mass

Symbol L_rm P

LP\mathcal L_{\rm P}
LPL_{\rm P}

What this part means

where mass stops being a fixed label and becomes something an object can carry a little more or less of depending on what it is doing internally.

Its job in the formula

LrL_rm P is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

The proper-time loop LP\mathcal L_{\rm P} is where mass stops being a fixed label and becomes something an object can carry a little more or less of depending on what it is doing internally.

The passage around this formula

The proper-time loop LP\mathcal L_{\rm P} is where mass stops being a fixed label and becomes something an object can carry a little more or less of depending on what it is doing internally. A composite system with an internal excitation of energy Δ\Delta E above its ground configuration carries additional rest mass Δ\Delta E/c2c^2 ,…
