This system of rest mass 9 kg will move with speed v1

Quote from: Yahya A.Sharif on 03/06/2021 16:32:25This system of rest mass 9 kg will move with speed v1What is causing it to move?

One cannot go from rest to the final speed without an acceleration. The acceleration; d/t/t, adds GR to SR; velocity is d/t. The acceleration adds a second time vector. GR, such as via the earth's gravity will cause a pressure increase with pressure able to lower the entropy; gas to liquid. Once we reach terminal speed; d/t and the acceleration; d/t/t is done, we lose the extra time vector and we are back to SR, where pressure is not a factor. The entropy will increase and absorb energy to satisfy the second law.

Suppose I have a rest mass m0 of 10 kg, part of this mass 1 kg converts to energy, E=mc² , E=e joules.In this case I will have a new rest mass m0 which is 10-1 kg or 9 kg .This system of rest mass 9 kg will move with speed v1 in which the relativistic mass for the system will be :m=m0/√(1-v²/c²) orm=9 / √(1-v1²/c²) Because no energy comes from out side, then m will be 10 kg and this for speed v1 and rest mass 9 kg *Now let's calculate the kinetic energy of the system :

But if you want to move those 9kg of rest mass, you need to apply some force to it, thus add some energy to the entire system.

However, only the mass source of GR will cause any phase changes of matter. In other words, I have never heard of an SR scenario that says if we approached the speed of light; SR, the space ship would collapse into a black hole. On the other hand, if we had enough mass in one area, gravity could cause the matter to collapse into a black hole. Both impact space-time but only GR can also alter matter. GR can cause nuclear fusion but SR does not. The question becomes what is the difference? The difference between SR and GR, is SR is constant velocity based while GR is acceleration based; velocity changing with time. The difference between velocity; d/t and acceleration; d/t/t is acceleration has a second time vector. They both share "d/t", which has the dimensional units of both velocity and space-time, but only GR has a second or additional time vector. This second time vector can cause matter to undergo phase changes; pressure induced fusion. Constant speed in space does not induce pressure. If you had a new fancy sports car, its acceleration creates G-forces. The force and pressures that one feels is often compared to gravity, via the expression G-force. One will not feel force and pressure at any steady state speed. Acceleration has an extra time vector, related to the force and pressure we feel. This time vector goes away once the final speed reaches steady state. We do not feel force or pressure with only d/t or velocity. The difference is time. Force and pressure can alter the free energy of a system via both changes in enthalpy and/or entropy. If we add pressure to water vapor, it will become a liquid, which define less entropy. If we pressurize oxygen and hydrogen gases we can induce an enthalpy change; combustion. The pressure can be mechanical, from gravity, from magnetic and/or electrostatic attraction. In all cases, we can alter the vapor into a liquid, since the phase change is connected to pressure and not the source of the pressure. G-force and gravity via mass can create the same pressure. Pressure is force/d2. The second time vector, has a connection to changes in free energy, via pressure. Pressure has a connection to another distance vector, that is the same in all references. It is connected to matter, pressure and phase changes. The second time vector of acceleration is being expressed as a secondary space-time* correlation that is not connected reference, but to material phases and their changes in free energy. SR does not show this secondary space-time* since it lacks the second time vector that is needed. This topic scenario is a trick question. The burning of mass, to create self propulsion of the remaining rest mass, will need to create an acceleration to move the rest mass from stationary to relativistic speeds. Within the propulsion and acceleration, will be that second time vector that can induce another distance vector via pressure. There are two space-times, one for reference and one for material phases; The laws of physics being the same in all reference is connected to the second space-time*, induced by a second time vector via acceleration. We can still cause water vapor to become liquid at constant velocity if we add pressure. In GR the extra time vector does this for us. If we only look at rest (mass) and final speed, we never take into account the GR* acceleration affects in the middle, but assume SR all the way. We get to ignore the impact of the second time vector, during fuel burn, associated with free energy changes via matter phase changes. This approach is condoned in physics. The analysis, although consistent with consensus thinking, demonstrates the fallacy of that biased thinking. The bias of transitions assumes, via space-time, that space and time is always connected. However, it ignores the second time vector of any form of acceleration. GR and SR show how this second time vector, by which GR and SR differ, can creates different affects in space-time including a secondary space-time affect connected to material phase changes and the subsequent changes in free energy.

However, it ignores the second time vector of any form of acceleration.

The energy to move it can come entirely from the object itself (case in point, an atomic nucleus undergoing spontaneous nuclear fission. All the energy needed to move the decay products can come from the binding energy of the nucleus itself).

Time is a dimension. It is not a vector. What do you understand a vector to be?

This isn't the first time he has said that time is a vector.

space-time reference

the same in all references.

that is not connected reference

The relativistic mass of the system is energy of the rest mass or energy of m0"m0c²" plus energy due to motion:K.E= m0c²/√(1-v1²/c²) + m0c²K.E= 9c²/√(1-v1²/c²)+9c²According to * and because m0=9 kg :K.E= 10c²+9c² or 19c² joules

He doesn't seem interested is explaining how he came to this erroneous conclusion he just likes to make the unsubstantiated statement.
