• TITLE: The Final Size of the Universe Based on the Elasticity of the Fabric of Spacetime

  ABSTRACT: We investigate the fabric of spacetime, its ability to stretch, curve, and expand. Through our continuous studies of accretion disks located at the core of galaxies, it is our conclusion that these disks are separate from the host galaxy stellar disk. Our research has also determined that the radius of accretion disks in spiral galaxies follow a consistent ratio according to the circumference of their adjacent supermassive black hole based on its Schwarzchild radius. We present evidence suggesting that galactic accretion disks are a key element to understand galaxy formation and can provide a precise calculation to how much the fabric of space will stretch. Once the degree of the elasticity of spacetime was established, we applied these measurements to the size of the universe at 380,000 years of age based on the imagery of the cosmic microwave background. This calculation provided us with the maximum diameter the universe will reach, an exact time when the universe will stop expanding, and where we are today within that timeline.
