NASA has confirmed in a press release that “something strange is happening” in the known universe, according to data collected by the Hubble Space Telescope; There is even talk of discovering “new physics” that directly interferes with the speed of the expansion of the universe.
According to the U.S. Space Agency, “the search for the rate of expansion of the universe began in the 1920s by astronomers Edwin B. It started with measurements made by Hubble and Georges Lomotre. In 1998, it discovered the “dark energy” of a mysterious driving force that would accelerate the expansion of the universe.
In recent years, however, with the help of Hubble, scientists have discovered that there is a significant difference between the rate of expansion measured in the local universe and (currently) independently obtained data that “predict different expansion values after the Big Bang”. ”; Simply put, the universe has changed its rate of expansion compared to the data left by “Super Bang”.
Now, although “the cause of this discrepancy remains a mystery”, the truth is that experts know that something strange is happening as data is being recorded that NASA has never seen before.
“Hubble data includes various cosmic objects that act as remote markers,” Support the notion that something strange is happening in relation to new physics”, Explains the space agency.
“A Milestone in Space History”
To explain (or at least try to explain) what is happening, the Nobel laureate Adam Rice of the Space Telescope Science Institute (STScI) and the University of Baltimore, Johns Hopkins, Maryland, said he and his team have dedicated themselves to exploring at least 42 supernova milestones. Hubble has been recording for the past 40 years.
“This is why the Hubble Space Telescope was developed, using the best techniques we know to do it. This may be Hubble’s masterpiece, as it takes Hubble 30 years to double the size of this model.Rice said.
Through this research, scientists were able to conclude that the last model of cosmic distance markers provided by Hubble was “more than double”, which made it possible to understand the speed of expansion of the universe a little more accurately. Path weather.
“The Hubble constant is a very good number. It can be used to inject a needle from the past to the present for the final test of our understanding of the universe. It took a tremendous amount of work, “said Dr. Lycia Verde, a cosmologist at ICREA and the ICC-University of Barcelona.
Therefore, it was determined that the rate of expansion of the universe is slower than what Hubble could see. With the help of a standard cosmological model of the universe and a data model provided by the European Space Agency, Astronomers predict the lowest value of the Hubble constant, which expands to 67.5 km / s and has an error margin of 0.5 km / s. However, the Riess panel’s estimate provides more data: 73 km / s per megaporse.
“Considering the large size of the Hubble model, there is only one chance in a million astronomers to be wrong due to the unfortunate draw,” Rice explained, making it difficult to study the expansion of the universe. Yet NASA adds that “it is difficult to find an explanation for the disconnect between the rate of expansion of the local universe and the early universe, but the answer may involve additional physics of the universe.”
