hubble
- n United States astronomer who discovered that (as the universe expands) the speed with which nebulae recede increases with their distance from the observer (1889-1953)
hubble's constant
- n (cosmology) the ratio of the speed of recession of a galaxy (due to the expansion of the universe) to its distance from the observer; the Hubble constant is not actually a constant, but is regarded as measuring the expansion rate today
hubble's law
- n (astronomy) the generalization that the speed of recession of distant galaxies (the red shift) is proportional to their distance from the observer
hubble's parameter
- n (cosmology) the ratio of the speed of recession of a galaxy (due to the expansion of the universe) to its distance from the observer; the Hubble constant is not actually a constant, but is regarded as measuring the expansion rate today
hubble-bubble
- n an oriental tobacco pipe with a long flexible tube connected to a container where the smoke is cooled by passing through water

hubel
- n United States neuroscientist noted for his studies of the neural basis of vision (born in 1926)
