Scientists have hung an extremely sensitive telescope on a balloon at an altitude of about 40 km above the South Pole, with the aim of trying to catch remnants of radiation left in the area after the big bang that created the universe
Yesterday, on April 26.4.00, space experts revealed a study according to which the world may be round, but most of the signs show that the universe is flat and will continue to expand forever. The British Mirror newspaper publishes this morning that scientists have suspended an extremely sensitive telescope on a balloon at a height of about 40 km above the South Pole, with the aim of trying to catch remnants of radiation left in the area after the big bang that created the universe about 20 billion years ago.
A group of research astronomers from the USA, Italy, Canada and Great Britain examined the data obtained and made the most accurate measurements possible to diagnose the geometric structure of the universe. The results show that the universe is flat, and support the theory that the entire universe was created from a small, hot subatomic region.
