Where Does the First Second of the Universe Fall on the Time Line?

I draw a straight line representing the time line of the universe. On this line I put a mark at 1cm and I say this represents the end of the Planck Epoch. So I can understand how tiny the Plank Epoch was, could someone tell me, how far along the line at this scale the first second of the universe would appear.
I imagine it would fall quite a distance along the line.

The Planck epoch ends at 10^-43 sec. after the big bang.
So if that time interval is represented by 1 cm. the line out to I second will be 10⁴³ cms. long. Now OOM the Hubble radius, crudely the radius of the observable universe, is 10²⁸ cms.

So your line will be 10¹⁵ times longer than the furthest distance we could possible see in the observable universe!

Does that give you an idea how short the Planck era is?

Thanks for that. I never realized it would be that much! The Planck Epoch truly is tiny and amazing to contemplate.
