How big is the universe in kilometers?

Answer 1

Hailey Alexander

Size of our universe is greater than #1.3055 X 10^23 km =130.55#

trillion billion km.

units of measurement

One billion is equal to 1000000000.

One trillion equals 1000000000000.

365.256363 x 24 x 60 x 60 s ÷ 1 year = 31558150 s

299792.258 km = 1 light second

For the elliptic orbit, 1 AU = a = 149597671 km

65242 AU is one light year.

The minimum 5-sd approximation for the diameter (size) of

our cosmos is

2 x 13.799 x 10^19 light years.

With this being an approximate 5-sd estimate, the number of SD in the solution

is limited, for reliability, to 5-sd.

In AU, this is #13.799 X 6.3242= 872.676 billion AU

In km uni, this is #1.3055 X 10^14# billion km

equals 130.55 trillion kilometers.

Note that the universe is the focus here, not the holistic

whole, #the# universe. Size 2 X 13.799 bly is the ( 2015 ) scientific

estimate the size of our universe using the Big Bang theory and

measurements,

The size of the universe is currently unknown. It is constantly expanding, and its size is beyond our current observational capabilities to measure accurately.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
