Where the earth's magnetic moment decay is also a rate which can and has been determined, according to current rates of decay earth's uninhabitability falls on this side of 50,000 years.

BWAAAAAAAAAAHAHAHA! You really are funny.

1. The "habitability' of the Earth is entirely unrelated to direction or strength of it's magnetic field.
2. The Earth's magnetic field has reversed itself many times in the past. It is always waxing or waning in one direction or the other.

BWAAAAAAAHAHAHA! I can't wait for your next "scientific" announcement of doom.

We'll be interested to learn of your fate as you try to colonize Jupiter or a magnetic star some day. Be sure to send us a post card. You are obviously sufficiently unaware of the part Earth's magnetic field plays in deflecting harmful solar activity. If I were you, I'd write to your bursar back at Starfleet Academy and ask for a refund.

In one direction or another, perhaps. No argumant there. Blinded by your mockery, the point lost on your inability to read and which you subsequently failed to address was that I was speaking of the inherent strength of the moment, not its position, which is tracked, and has found to be diminishing over time at a measurably and remarkably consistent rate.
