Question

The presence of Dark Energy can be seen from the measured flatness of the Universe If the OBSERVABLE universe is 93.6 Gly across, but is considered to be flat within a margin of error of 0.41%, what is the absolute minimum size (diameter in Gly) of the ENTIRE universe?

Answer 1

93.21624 Gly

Step-by-step explanation:

The size of the universe without considering flatness 93.6 Gly

Error percentage = 0.41%

So error
`=93.6* (0.41)/(100)=0.38376\ Gly`

So size of universe when we consider flatness
`=93.6-.38376=93.21624Gly`

Note - if there is any flatness then size will decrease so diameter also decrease
