Seeing from the relays i've potentially created a time travel device.

If it can incrementally increase in speed per segment of the loop,

as the ship moves forward, who knows.

But another factor must be adhered to.

That is, the locking position of the ship at the center of the tunnel.

So this position must be amplified by reverse polarity of magnetism,

strong enough so that the increasing speed of the ship,

does not escape its clutch.

Which may depend on the size of the tunnel (big)

and how small the ship is in comparison to that,

alongside its amplification.
