Hello Hailey,
Just an addition to the above excellent definitions.
"apparent" means 'seeming' as opposed to 'real'.
It means it is a false appearance not actual or genuine.
In your example it manifests to people on the basis of evidence that our time is uncertain, while their speculations based on those evidences may not be real.
Another Example:
"Are gender differences more apparent than real?"
Meaning do they seem existent as a theoretical speculation based on evidence of actual differences or are they imaginary and invalid?
"The differences between both methods may be more apparent than real."
It means they seem different ,while in fact they may not be so.
