"The Earth is acting like a giant vacuum cleaner powered by gravity in space, pulling in particles of dust," says Dr Smith

This goes to emphasize that it is high time we find an alternate planet for survival

Interesting find James - I never considered this question before.

anonymous · Answer

A doubt James. If the mass of the Earth would change, wouldnt the time period of the Earth's Rotation Change as: 
No external torque in space, 
I x (angular velocity) is constant. So if I changes, omega changes?

jamesj · Answer

Yes, definitely.  But as the loss is only ~0.000000000000001% of the total mass per year, the period change is likewise tiny.
