Web8 mrt. 2024 · Hubble was the son of John Powell Hubble, a businessman who worked in the insurance industry. His mother, the former Virginia Lee James, was a homemaker who … WebHubble's initial value for the expansion rate, now called the Hubble Constant, was approximately 500 km/s/Mpc or about 160 km/sec per million-light-years. The expansion age of the Universe inferred from this was only 2 Gyr, but by the 1930's, radioactive dating of rocks had already shown geologists that the age of the Earth was 3 Gyr.
This is slightly different from the age of the universe which is approximately 13.8 billion years. The Hubble time is the age it would have had if the expansion had been linear, and it is different from the real age of the universe because the expansion is not linear; it depends on the energy content of the universe … 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. In other words, the … Meer weergeven A decade before Hubble made his observations, a number of physicists and mathematicians had established a consistent theory of an expanding universe by … Meer weergeven Start with the Friedmann equation: where $${\displaystyle H}$$ is the Hubble parameter, $${\displaystyle a}$$ is the scale factor, … Meer weergeven The value of the Hubble constant is estimated by measuring the redshift of distant galaxies and then determining the distances to them by some other method than Hubble's law.
