Sure they are. You're not being creative enough if you can't figure out how (hint: they can affect the orbital trajectories of some pretty large objects, which can themselves affect the orbital trajectories of some really big objects).

There's a famous story about Trinity where the scientists all bet on the blast magnitude, and a visiting general made a ridiculously huge prediction, way above what they hoped for, in order to flatter his hosts. He won; the blast was still far more powerful than his seemingly fanciful, signaling-motivated guess but he came the closest.

It will go boom and look bright. I dunno what else, I just clear the floors.
