This seems to always happen when people try time travel. Circular events always happen... tonight on Lost it also happened. Try to follow this

Desmond got the numbers (2.342 and 11 Hz) from Faraday in 2004...
This means that Faraday had the numbers already from before 2004.

Desmond gives the numbers to Faraday in 1996, and it completes his experiment with elouise the lab rat...
This means that Faraday didn't know the numbers before Desmond gave them to him.

Here's the circle: Desmond got numbers from Faraday in 2004 that Faraday knew about because Faraday got the numbers from Desmond in 1996.

What came first the chicken or the egg?? In this case neither.

Time travel paradoxes suck.
