The mathematical expressions of the laws of physics employ a set of twenty physical constants that appear to be static across the observable universe.
The table presents a list of important physical constants.
Each one would correspond to a different condition of space-time, with a different set of physical constants.
Other standard measurements depend on physical constants, not human-made artifacts.
In recent times, however, the units tend to be defined in terms of the physical constants.
If different laws or physical constants prevail in other bubble universes, the conditions may not allow the existence of life or intelligence, he explained.
The numerical values of the physical constants depend on the system of units in which they are expressed.
We have to look at past episodes because economic theory, lacking the physical constants of the hard sciences, has never offered a complete account of the mechanics of depressions.
The voltage across a Josephson junction is known on theoretical grounds to be dependent only on the values of certain basic physical constants.
In each instance, biophysicists have calculated, the system couldn't get faster, more sensitive or more efficient without first relocating to an alternate universe with alternate physical constants.
The CGPM in 2011 agreed to a proposal to begin to redefine the kilogram, the ampere, the mole, and the kelvin in terms of fundamental physical constants.
