Not really.
Electrons do have mass, but a device powered by an electric current will generally have the electrons flowing out at the same rate that they flow in.

If you're talking about making a map of the astrophysical or cosmological backgrounds of gravitational waves -- you're right. As you integrate (i.e. capture more data), the noise will tend to cancel out while the signal will reinforce itself. But the problem is that the signal-to-noise-ratio is so small -- essentially zero -- that, with current detector sensitivity, it would take literally forever to get an image with any features at all.

Doing laundry in Poland, I was grateful for the standard icons, whose meaning a quick Google search revealed.
