Is Infinitesimal is same as infinite?

[James11221]

Is infinitesimal the same as infinite? Because

1. infinitesimal makes no sense as you can't be infinitely small as infinite itself has no limit in size nor indication it changes size
   
   
2. Granting this statement, are dimensions which are labelled infinitesimal just another way of saying these are infinite?
   
   Infact we don't even know if our universe was infinitely small just that it was compact or my lord created it

 

[AlexSamDen]

It isn't the same
In simple terms, Infinitesimal is 1/infinity

 

[DarkDragonMedeus]

It's literally the opposite of infinite; infinisimal is the smallest possible finite number without reaching 0 is textbook definition.
