The study demonstrates that faster-than-light travel requires negative mass. Mass must decrease as velocity increases and must be negative beyond the speed of light. It also proves that there is no absolute speed limit in the universe, contradicting faulty Einstein's theory of relativity and quantum theory. The study also reveals that relative motion depends on relative coordinates, not reference frames. It is demonstrated that gravitational and inertial control of mass is the basis of faster-than-light travel. A hypothetical spaceship is described, and physical calculations are made to demonstrate the possibility of traveling faster than light. The study also explores the potential effects of gravitational interaction and collisions. The technology is proposed for instantaneous cosmic communication and other applications of negative mass using the free energy of the gravitational field.

• Is faster-than-light travel indeed possible?

• What kind of propulsion could achieve such a technology?

• Could any matter be traveling faster than light?

• Could living beings be traveling faster than light?

• What could be the consequences of that?

The above questions will be scientifically answered through this study in accordance with the negative mass theory.
