How Fast Is The Universe Expanding Worldatlas Space itself is pulling apart, approximately expanding at a rate of 74.3 ±2.1 kilometers per second per megaparsec the most precise measurement ever made of the speed of the universe's expansion was made by nasa's spitzer space telescope with "per megaparsec" i mean distance of one million parsecs or 1mpc astronomers typically express the distances between neighbouring galaxies (such as milky. Answer link. our galaxy is 100 180 k ly wide, with 2 k ly bulge at the center. our universe is expanding at the rate of 71 km sec mega parsec. here, ly = light year unit of distance = 62900 x ( earth sun distance), nearly, and k = 1000 the greater unit of distance, mega parsec = million parsec, where parsec = 206265 x ( earth sun distance.

How Fast Is The Universe Expanding The expansion of universe varies as distance increases as per hubble law. recessional velocity= h0 x r where h0= hubble constant r= recessional velocity. hubble constant is 73 km second mega parsecond. so to find expansion rate you have to multiply with hubble constant with distance to object. picture about space . This means that for every megaparsec — 3.3 million light years, or 3 billion trillion kilometers — from earth, the universe is expanding an extra 73.3 ±2.5 kilometers per second. the average from the three other techniques is 73.5 ±1.4 km sec mpc. perplexingly, estimates of the local expansion rate based on measured fluctuations in the. 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. Webb measurements shed new light on a decade long mysterythe rate at which the universe is expanding, known as the hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos. however, a persistent difference, called the hubble tension, is seen between the value of the constant measured with a wide range of independent distance.

The expansion of the universe is the increase in distance between gravitationally unbound parts of the observable universe with time. [ 1] it is an intrinsic expansion, so it does not mean that the universe expands "into" anything or that space exists "outside" it. to any observer in the universe, it appears that all but the nearest galaxies. Astronomers have known for decades that the universe is expanding. when they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from earth. to astronomers.
