Comment on DC Theory: negative voltage

And a quick followup:
If the ground was moved to the T3 junction than the battery’s negative terminal would be common to ground and the voltages values across all loads would go back to being positive in regards to the battery’s negative terminal (T1 = 1000V, T2 = 333V, T3 = 0V) ?

Funny thing - regardless of where you put ground, all the voltages are positive relative to the negative battery terminal. Because voltages are always in reference to something (usually our reference is ground or the negative terminal). If you ever have to measure voltage, you’ll notice the device has two probes - you can only measure voltage between two points.
