Meaning
zero point (plural zero points)
(military) The location of the center of a burst of a nuclear weapon at the instant of detonation. The zero point may be in the air, or on or beneath the surface of land or water, depending upon the type of burst, and it is thus to be distinguished from ground zero.
zero-point (not comparable)
(physics) associated with zero on any scale, but particularly with a temperature of absolute zero

"Everybody who says the same words is the same person if the spectra are the same only they happen differently in time, you dig? But the time is arbitrary. You pick your zero point anywhere you want, that way you can shuffle each person's time line sideways till they all coincide.
The only number that would ever be enough is 0. Zero pounds, zero life, size zero, double-zero, zero point. Zero in tennis is love. I finally get it.
Additionally, some field theories were proven to be exactly equivalent to free theories (whose vacuum expectation values were zero), and so again, we assumed that the zero-point energy was zero.
Although the Casimir effect can be expressed in terms of virtual particles interacting with the objects, it is best described and more easily calculated in terms of the zero-point energy of a quantized field in the intervening space between the objects.
Also, the microscopic properties of helium-3 cause it to have a higher zero-point energy than helium-4.
Assuming the energy of rotating diatomic molecules contains zero-point energy, they then compared the theoretical specific heat of hydrogen gas with the experimental data.
