Answer 1

Answer:

The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It's so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.

The structure first came to light as the research team (led by Istvan Horvath of the National University of Public Service in Hungary) was looking at brief cosmic phenomena known as gamma-ray bursts. It is thought that they come from supernovas, or massive stars that explode at the end of their lifetimes.

Answer 2

The universe is the biggest of all.

• The universe is a collection of galaxies. There is only one Universe and everything that exists in this Universe itself.
• The proper as would be measured at a specific time, including the present between Earth and the edge of the observable universe, is approx 46 billion light-years (14 billion parsecs), making the diameter of the observable universe about 93 billion light-years (28 billion parsecs).
