Tolong jelaskan mengenai Momentum of massless objects dari Moméntum dalam bahasa sunda

Objects without a rest mass, such as photons, also carry momentum. The formula is:

is the wavelength of the photon,

is the energy the photon carries and

is the speed of light.

Momentum is the Noether charge of translational invariance. As such, even fields as well as other things can have momentum, not just particles. However, in curved space-time which is not asymptotically Minkowski, momentum isn't defined at all.
