RAM stands for random-access memory, which makes it possible to find specific information very quickly. It is a form of fast-access, volatile storage that is used as the main memory in computer systems. The most widely used form of RAM for the main memory is dynamic RAM (DRAM).

In the video it states that VY Canis Majoris is 2,800,000,000 km in diameter and that it would take 1100 years travelling in jet aircraft at 900km/hr to circle it once.The diameter of VY Canis Majoris originates from a study and paper submitted by Professor Roberta M. Humphreys from the University of Minnesota.n her document Professor Humphreys concludes that VY Canis Majoris is between 1800 and 2100 solar radii. (The solar radius is approximately 695,500 kilometres (432,450 miles) or about 110 times the radius of the Earth, or 10 times the average radius of Jupiter.
