TL;DR Summary

Time dilation has been observed in quasars in the early universe, confirming Albert Einstein's theory of general relativity combined with the expansion of space. A new study using observations of 190 high-redshift quasars over 20 years has revealed that time in these quasars appears to run five times slower than it does on Earth. This discovery provides further evidence of the universe's expansion and supports the Big Bang theory.
