# Cooper pairs by electron-gravity interaction?

The article on Wikipedia on BCS theory mentions

In conventional superconductors, an attraction is generally attributed to an electron-lattice interaction. The BCS theory, however, requires only that the potential be attractive, regardless of its origin.

But an attractive potential between two electrons could also be the gravity between electrons, correct? So could it be possible that Cooper-Pairs of electrons form purely by their gravitational interaction?

• No, Cooper pair formation is due to an effective potential and symmetry breaking. The force of gravity between two electrons is negligible for Cooper pair formation. – user106422 Oct 27 '16 at 20:22
• The electric force between 2 electrons is always $4.1 × 10^{42}$ times as great as the gravitational force between them, at any artibrary distance. – user108787 Oct 27 '16 at 22:27
