The "filter out the effects of gravitational forces" means that the measured particles were in free fall; in free fall there is no gravitational force.

- kenjackson 5y agoIs that the common way you'd express that they were measured in free fall -- that the effects were "filtered" out? That seems like an odd way of saying it, but I'm not a physicist.
- pdonis 5y agoI don't think it's a very good way of expressing that the objects were in free fall, no. Nor, as far as I can tell, does the actual paper (as opposed to the pop science article) use such an expression.
