The surprise discovery of a vast void in the universe will give a new dimension to the study of the development of the universe. Cosmology probes how cosmic structures developed in the universe after the Big Bang. The discovery raises questions about the current understanding of the development of the universe since the void is much larger than expected.
The spot lying about 10 billion light years away contains no stars, planets or dark matter. It is thousand times bigger than any other known void. It has been under observation for the last three years. The gigantic void was spotted by researchers from the University of Minnesota, us. The team was studying data from a survey carried out by a Very Large Array radio telescope in New Mexico.
Small particles crossing the void are found to be losing more energy than those passing through space filled with matter."What has been observed is that the temperature of the cosmic microwave background (cmb) radiations is slightly lower in a region in the sky. cmb is the radiation we receive from the early universe when the universe was hotter and smaller than it is today," says Jasjeet Singh Bagla of the Harishchandra Research Institute, Allahabad.
