Hubble Trouble How Fast Is The Universe Expanding Science Aaas The values for h0 of 73 km s mpc vs. 67 make real differences in the age of the universe using cosmology calculators. 13.083 gyr old universe now and for the cmbr with postulated redshift of 1100. Their new observations, made using hubble, indicate that the expansion rate for the nearby universe is just under 70 kilometers per second per megaparsec (km sec mpc). one parsec is equivalent to 3.26 light years distance. this measurement is slightly smaller than the value of 74 km sec mpc recently reported by the hubble sh0es (supernovae h0.
We Don T Know How Fast The Universe Is Expanding And That S A Problem The number indicates that the universe is expanding at a 9% faster rate than the prediction of 67 kilometers (41.6 miles) per second per megaparsec, which comes from planck's observations of the early universe, coupled with our present understanding of the universe. Depending on the values deduced for the expansion rate, the universe could be anywhere between 10 and 20 billion years old. over the past 34 years hubble has shrunk this measurement to an accuracy of less than one percent, splitting the difference with an age value of 13.8 billion years. this has been accomplished by refining the so called. We have known the universe is expanding over time ever since 1929, when uchicago alum edwin hubble (sb 1910, ph.d. 1917) made measurements of stars that indicated the most distant galaxies were. Prior to hubble’s 1990 launch, observations from ground based telescopes yielded huge uncertainties. depending on the expansion rate, the universe could be anywhere between 10 to 20 billion years old. for the past 34 years hubble has shrunken this value to an accuracy approaching one percent. this has been accomplished by refining the so.
