How Big Is The Observable Universe In Kilometers. How do we know how old the universe is? Part of the problem is that the hubble constant can be different depending on how you measure it.
And we all know the famous maxim from albert einstein’s special theory of. Recent research had taken it up to 93 bly. Multiply that by all the seconds in one year, and you get.
So, The Diameter Is Within (27.6, 93) Bly.
Web light zips along through interstellar space at 186,000 miles (300,000 kilometers) per second (more than 66 trips across the entire united states, in one second). Double this can be used as the least diameter of our universe. A distance of 380,000 kilometers is on the edge of being conceivable on a human scale.
The Universe Is A Very Big Place That Contains Everything—Including The Things We Can And Cannot See.
How big is the universe that we can see? From the virtual center of our universe, the distance of the earth is estimated to be 13.8 billion light years (bly). Web the diameter of the observable universe is about #4.40# x #10^23# km.
Our Best Guess Is 540 Sextillion (Or 54 Followed By 22 Zeros) Miles;
How do we know how old the universe is? Web this baseline puts the age of the universe at approximately 13.7 billion years. The diameter of the observable universe is about 46.5 billion light years or #4.40# x #10^23# km.
I Consider This As Upper Bound For The Diameter.
The earth, sun, milky way, black holes, and other stars and galaxies are all part of the universe. Part of the problem is that the hubble constant can be different depending on how you measure it. On this scale, the nearest spiral galaxy, andromeda, would be another cd about eight feet away.
1 Light Second =299792.258 Km.
Wilson astronomer estimates milky way ten times bigger than thought, harlow shapley studied the distances to globular clusters to determine the size of the milky way galaxy to be 300,000 light years across. Web 1 year = 365.256363 x 24 x 60 x 60 s = 31558150 s. Web the actual distance between earth and the moon varies throughout the moon's orbit, but the moon's average distance is approximately 384,402 kilometers.
