Is there any evidence that objects moving increasingly closer to light speed gain gravitational mass, in the sense of attracting surrounding (and not co-moving) masses more strongly, rather than solely possessing the increased inertial mass implied by the greater force necessary to accelerate/decelerate it?
I can see that, for the laws of physics to not be noticeably different on, say, a fast-moving, non-accelerating rocket ship, the speed with which objects on the ship gravitate toward one another must be unchanged, so that if those objects' inertial masses increase, so must their gravitational masses. I consider that indirect evidence of gravitational mass increase. But what about the ship's (direct) gravitational effect on passing, more-or-less stationary objects?
