What if our biological clocks are being synced with pulsars?

Pulsars are neutron stars the emit pulses of electromagnetic radiation, which can be detected if they are directed towards the Earth.

I have read that many of the cells in our body have their own timing mechanisms (their clocks) and they are controlled by the Suprachiasmatic Nuclei (SCN) found in our hypothalamus.

What if our SCN are themselves controlled by Pulsars like the Vela Pulsar, which are so accurate that they were once used as a proper source of time.

This is just a theory of mine, which I found amusing. But, a fact is that SCN, our master clocks, are actually synced by the Sun’s light.
