Hi all. I was trying to imagine gravitation as a causal effect of time dilation and have relatively little schooling so...(adsbygoogle = window.adsbygoogle || []).push({});

With frames of reference obviously a high degree of time dilation is attained with a relative velocity close to c. however I understand a large stellar object such as a planet also has a frame of reference, not simply for its relative velocity vector but also due to its inertial frame, thus as I imagined its impact upon spatial topography is quite intense.

Fast travelling small objects get a bit of inertia going up around c. too, I've been told they also generate some amount of gravitation/regional spatial topography.

So my questions are:

what is the math (fairly simple version) for calculating the "gravitational effect" of a small object (say...10 tons) travelling a relative velocity close to c. (say...0.98c or lambda=5/is this correct way to express?) ?

secondly how is an inertial frame which is relative to rest mass (M_o ?) described in math? Is there a simple equation like the Lorentz transformation for that? Does it describe the factor of time dilation and degree of gravitational influence?
