How long was a day when the universe began

[IndigoChild5559]

It's quote possible it was a shorter time. No one was here to record it but we do have ways of measuring things. Like the moon leaves at 30mm per year.

Like a lot of scientific conclusions, what we have now could be used to calculate it. Who knows.

The universe has existed for 13.2 billion years. The earth has existed for 4.5. So for billions of years time passed with no earth rotation to mark a day, or earth orbit to mark a year.

In timely news, scientists have determined that some 1.4 billion years ago, an Earth day—that is, a full rotation around its axis—took 18 hours and 41 minutes, rather than the familiar 24 hours

Many arguments here about the bible and creation are about "a day". We all only know the concept of "a day" as we live our lives here on earth.

How long was a day when the universe became the universe?

That is a really complicated question, you can see the trouble it causes among physicists and folks who understand some aspects of the math:

" How long was a day when the universe began"

It is a period of time not a " day" as is commonly understood/misunderstood, please, right?
