The universe's expansion rate is still a mystery | Science News
These morons ought to duel this out with pitchforks, and refund everyone's tuition, because yesterday this was taught as fact and SIMPLETONS believed it.
SANTA BARBARA, Calif. — It’s one of the most talked-about issues in physics: Two measurements of the universe’s expansion rate disagree. Now, a technique that aimed to resolve the mismatch has produced a third estimate that falls between the previous two. So the controversy endures, scientists report in a study accepted in the Astrophysical Journal.
One measurement of how fast the universe is expanding — a number known as the Hubble constant — comes from supernovas, or exploding stars. Another is based on the cosmic microwave background, the light released shortly after the Big Bang. Previous supernova measurements indicate that the universe is expanding at a rate of about 74 kilometers per second per megaparsec, or about 3.3 million light-years. But the cosmic microwave background pegs that number at around 67 kilometers per second per megaparsec.
Yawn
