The observable Universe is greater than 12 x 109 light years in radius.
(12 x 109 years)(365 days) (24 hr) (60 min) (60 sec) (3 x 108m ) ( 1 km )
( year ) (day ) ( hr ) ( min ) ( sec ) ( 103 m )
= 2 x 1021 km !!!! (20000000000000000000000 km)

Atomic orbitals…regions in space where the electrons hang out.
The mass of an electron is 9.1 x 10-31 kg. It is not possible to know precisely where an electron is now and where it is going at the same time
