Calculations of the Width of the Universe Based on Hubble C.

I did a quick spreadsheet of a distance an object travels at Hubble Constant for a period of 13.7 years. Hubble Constant is an acceleration number, meaning it increases with time. Best estimate is around 50 to 100 Km/Sec for every Mpc. One Mpc

= 1,000,1000 Pc, one Pc = 3.26 light years of traveling.

I used for now 50 Km/Sec Mpc. I had 4,205 spreadsheet entries, or the speed doubled 4,205 times to reach 13.7 billion years. The speed of the object increases with time. I used the speed as a percentage of the light speed then calculated the distance in Billions of Light Years.

Assuming galaxies accelerating through the universe from the time of the Bing Bang (13.7 Billion years ago) at an accelerating Rate of 50 Km/Sec/Mpc, then the universe or the farthest galaxy (Last Column) traveling in space at any given time (first Column), see below:

Billions of Years Speed of Moving Galaxies in Km/Sec Speed in Light speed Distance in Billions of light yrs

0.00326 50 0.00016666 5.43333E-07

1.00082 15350 0.051166667 0.051208623

2.01794 30950 0.103166667 0.208184143

5.00084 76700 0.255666667 1.278548093

13.7083 210250 0.700833333 9.607233583

That means the universe is 9.6 billion light years in width, however, if Hublle Constant is 100 Km/Sec/Mpc then that number could be 20 billion light years. I have see some estimate as high as 500 Km/Sec/Mpc.
