This article describes electromagnetic origin of gravity and describes techniques to generate gravitational field that has the opposite sign to that of Earth.
Following ignition of its nuclear synthesis, a newly created star ejects laser-like jet of matter along its axis of rotation. This matter, accelerated to relativistic speeds, interacts with the surrounding gas, producing light that we can see. This image provides a cosmic illustration of the hypothesis presented in the article above. Credit: NASA Hubble telescope 12 March 2022
