Hubble theorem
Web10 dec. 2015 · The Hubble telescope, like many others, uses a single very large, curved reflector machined to incredible precision as its primary light-gathering element. The design goal of Eyeglass was to expand the main element to a diameter of 100 meters — about a football field. Making a single reflector 100 meters in diameter with an optical precision ... Hubble's law is considered the first observational basis for the expansion of the universe, and today it serves as one of the pieces of evidence most often cited in support of the Big Bang model. The motion of astronomical objects due solely to this expansion is known as the Hubble flow. Meer weergeven Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance.

Webwhere is the Hubble constant. This equation is identical to the one which governs the behavior of a massive scalar field such as axion. Thus, the massive gravitons will be efficiently produced during inflation (cf. Ref. [ 41,42]). One may estimate the amount of the gravitational waves produced. Web15 dec. 2024 · This animation shows the explosion of a white dwarf, an extremely dense remnant of a star that can no longer burn nuclear fuel at its core. In this "type Ia" supernova, white dwarf's gravity steals material away from a nearby stellar companion. When the white dwarf reaches an estimated 1.4 times the current mass of the Sun, it can …
