In simple terms, Hubble’s law is the scientific phenomenon that states the universe is getting bigger and bigger at a faster and faster rate. From that, the distance can be calculated using the formula v = H0 * d. Depending on whether or not delays exist between MBHs and galaxy mergers, these heavy-seed models are referred. Hubble’s law can be used to measure distance when an estimated velocity can be known. a galaxy) moves away from us it is 'red-shifted' as the wavelength of light is 'stretched' so the light is seen as 'shifted' towards to red end of the spectrum, according to. By precisely determining the expansion rate, called the Hubble constant, the cosmic clock can be rewound and the age of the universe calculated. How is Hubble’s law used to measure distance? Hubble noted that light from faraway galaxies appeared to be stretched to longer wavelengths, or reddened, a phenomenon called redshift. Hubble’s law tells us that the universe is expanding at an ever-increasing rate and the further away an object is from our reference point the fast it is moving and the fast it is accelerating. Second, you will estimate the galaxies absolute magnitudes. Hubble’s law is an equation that describes the speed at which a galaxy is moving away from our own in our expanding universe. These redshifts will be used to calculate Vr, the speed at which the galaxies are receding from us. To calculate the velocity of a galaxy, multiply the distance to the galaxy by the Hubble constant. In equation form, Hubble’s law is v H0d, where d is the distance to the galaxy, v is the velocity with which it’s receding, and the proportionality constant, H0, is the Hubble constant. H0 is the Hubble constant (km/s/Mpc) (Mpc = mega-parsecs). ![]()
