Scientists Doubt About Expansion Rate Of The Universe A New Search For

Scientists Doubt About Expansion Rate Of The Universe A New Search For The puzzle, called the "hubble tension," is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe’s evolution. scientists using nasa's hubble space telescope and many other telescopes consistently find a. Reiss, saul perlmutter and brian p. schmidt won the 2011 nobel prize in physics for their 1998 discovery of dark energy, the mysterious force behind the universe's accelerating expansion.

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. The webb data confirms the accuracy of 30 years of hubble observations of cepheids that were critical in establishing the bottom rung of the cosmic distance ladder for measuring the universe’s expansion rate. download the high resolution cepheid graphic. image credit: nasa. esa, j. kang (stsci). science: a. riess (stsci).

Furthermore, there is one star in particular that scientists like to focus on with hubble to tease out the universe's expansion rate: cepheids. these are supergiant stars with something like. Webb confirmed that the hubble telescope’s keen eye was right all along, erasing any lingering doubt about hubble’s measurements. at the center of these side by side images is a special class of star used as a milepost marker for measuring the universe’s rate of expansion – a cepheid variable star.
