NASA’s James Webb Telescope and Hubble Space Telescope to investigate the truth behind the Universe’s expansion rate in Hubble Tension.
Scientists are grappling with a puzzling discrepancy known as the “Hubble Tension,” which suggests that the universe is expanding at a faster rate than previously thought. To address this issue, NASA’s James Webb Telescope and Hubble Space Telescope are teaming up to analyze high-resolution data and uncover the root of the problem. Cosmologists are working to resolve the inconsistencies and improve the accuracy of our understanding of the universe’s expansion.
The expansion rate of the universe
According to a NASA report, the Hubble Space Telescope has been studying the current rate of expansion of the universe. Now the James Webb Space Telescope has also joined the team to bring accurate measurements and avoid errors in the process. It was previously thought that Hubble’s measurements of the expansion rate were accurate. However, scientists believe that they may encounter errors in measurements as they delve deeper into understanding the universe. Adam Riess, a physicist at Johns Hopkins University in Baltimore, said: “We have now covered the full range of Hubble’s observations, and we can rule out measurement error as the cause of Hubble’s tension with a very high degree of certainty.”
Scientists have used several methods to measure relative distances in the universe, these methods are known as cosmic distance ladders. Scientists study discrete objects, which help them measure the expansion rate of the universe. However, there may be some inaccuracies in the method, but scientists believe that both the James Webb Telescope and the Hubble Space Telescope together will prove to be very useful in understanding our universe. Riess said: “Combining the Web and Hubble gives us the best of both worlds. We find that Hubble measurements remain reliable as we climb further up the ladder of cosmic distance.”
