This message contains information sufficient enough to write a science fiction novel. But at the same time, this message contains information sufficient enough to create more advanced devices for moving in space-time, provided that the separation technology I wrote about earlier exists. To clarify our understanding of the separation technology, let’s imagine that we can only observe a positive electric charge. Two colliding protons (electric charge – two pluses) with sufficient energy can generate a particle-antiparticle pair (an electron and a positron). Their total electric charge has not changed (three pluses and one minus). But three positively charged particles will already be observed – two protons and one positron. The presence of an electron can only be concluded from the “incorrect” motion of two protons and one positron. And finally, when an electron and a proton form a neutral hydrogen atom, two particles will again be available for observation. Only this will be one proton and one positron. If we remove high-energy protons from this description and replace the electric charge with energy, we will get an approximate description of the separation technology. In some volume, an increase in the energy/mass of particles will be observed. But only because exactly the same in magnitude but opposite in sign additional energy/mass is not directly observable. Now if we throw away the additional energy/mass far enough, then in the same volume there will be the same positive energy/mass and additional negative energy/mass. Unlike electromagnetism with a simple summation of positive and negative charge, the required gravity configuration leaves the amount of energy (both positive and negative) unchanged with a decrease in mass (both positive and negative). Someday the gravity configuration will be described in detail with pictures and formulas, not now. Now about the ratio of positive and negative energy/mass. If an object has only positive energy equal to its mass multiplied by the speed of light in a vacuum to the second power, and there is no negative energy/mass, then such an object is at rest in space. If negative energy/mass is added to an object and its energy (in absolute value) is greater than its mass multiplied by the speed of light in a vacuum to the second power (also in absolute value), then the ratio of its energy to its mass multiplied by the speed of light in a vacuum to the second power (the Lorentz factor) will entirely determine its speed in space. If the mass (by adding negative mass) and energy (by configuration) of such an object are set to zero (in total), then it ceases to belong to the Universe and the limit on motion with the physical (not observable) speed of light in a vacuum disappears – the very concept of speed disappears. Conclusion. If more negative energy/mass is added to an object than the object initially had positive energy/mass, then the ratio of its energy to its mass multiplied by the speed of light in a vacuum to the second power (the Lorentz factor) will also entirely determine its speed in space … and in negative time. That is, such an object will freely cross any region of space occupied by any matter (up to a neutron star) in positive time.
