Time traveller went to year 8973 and met telepathic robots PASSES lie detector

Which is more likely?

That lie detectors can be fooled, or that time travel is possible?

8973? Sounds like it might be from a 1973 story with 7000 years addded, this seems a bit mundane an extrapolation for 7000 years in the future anyway. If it can be comprehended, or put into words it'll be a huge let down.

This headline is tabloid nonsense. Lie detectors do not detect lies[1].

Even if they did, an insane, delusional person telling this story could pass one because they wouldn't believe they were lying.
