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 :

Answer:

93.21624 Gly

Explanation:

The size of the universe without considering flatness 93.6 Gly

Error percentage = 0.41%

So error [tex]=93.6\times \frac{0.41}{100}=0.38376\ Gly[/tex]

So size of universe when we consider flatness [tex]=93.6-.38376=93.21624Gly[/tex]

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