JWST Discovers Four Oldest Galaxies in Observational History
The powerful James Webb Space Telescope (JWST) is bringing us new insights.
for example,In February 2023, we will discover six massive galaxies that appeared just 500 to 800 million years after the Big Bang.Did.
The performance of the James Webb telescope is too great and the “Big Bang cosmology” is forced to be revised
The mass of these galaxies is100 billion times the mass of the SunTherefore, it is thought that the galaxy grew quite rapidly after its birth.
However, that growth rate is implausible under current theory, so the researchers believe that the newly discoveredThe existence of massive galaxies is ‘99% inconsistent with current cosmological models’and caused a great deal of discussion.
Many people are therefore hoping to find out if this discovery was just a mistake or if it could lead to a correction in cosmology.
Meanwhile,JWST “discovered 4 new galaxies”I reported.
This has been observed so faroldest galaxyThen, the area more than 13 billion light years from the earth, that is,Born 300 to 500 million years after the Big BangIt is estimated that
theseThe oldest of the four galaxies was born 320 million years after the Big Bangdoing.
This is due to the big bangdark agesAfter , the matter in the universe isReionizationIt is the timing that caused the 1980s, and it is also called the “dawn of the universe” when the early celestial bodies of the universe were born.
Then, what kind of properties did the discovered ancient galaxies have?
