Can there be technology, that manipulates spacetime and makes distances meaningless?

"During a major science and technology conference in Texas, the Trump Administration’s top science official claimed that the United States now possesses technology that can “manipulate time and space” and “leave distance annihilated.” (InterestingEngineering, US official claims America can ‘manipulate time and space’ in bombshell tech reveal) 

Things like quantum stealth are under research. The fact is that those things that Trump's government to science officers say that the U.S. owns technology that can possess space and time can mean anything. 

That can mean. That there are theoretical models for that thing. 

There can be tests for models. Or there can be some more- or less-working models. 

That is one of the most interesting and fundamental things in the world. Manipulating spacetime by adjusting the energy level in an object, its shell, or outside the object is possible. In the quantum world, it is possible to make time move backward in particles pumping energy into them. That thing makes it possible to turn particles young again. 

But the question is anyway: can we bring information from the future to the past? That thing can be possible by sending particles to the future by adjusting their energy level. So we can put particle spin very fast. And if the particle's energy level rises high enough. That makes the particle travel to the future. 

Researchers can slow time using the cylinder that spins extremely fast. If the cylinder spins with a speed that is very close to the speed of light. That slows time in that device. Slowing time or time dilation makes it possible for people like fighter pilots to have more time to react to things like missile launches. 

In some models, there can be a saucer-shaped structure or craft. There is a particle accelerator on its outer edge. That particle accelerator will make the particle spiral which slows time in that craft. 

There is the possibility that the physical structure of the Tipler cylinder is replaced using an ion whirl. The fast-moving ion whirl slows time in the cylinder. If we want to travel to the planet Neptune slowing time is enough. But if we want to travel back in time, that system requires that the cylinder rotates faster than light. And that is the problem because the speed of light cannot be crossed. But that kind of structure can open the path to the entire solar system or make fundamental advances in air combat, even if it could slow time only 50%, That means 10 seconds outside is 15 seconds in the cabin. 

Another particle will be put into superposition and entanglement with it. If that particle in the future has a higher energy level than the particle in the laboratory quantum entanglement can make a so-called causality loop. Bringing information from the future into the past doesn't mean that it's possible to make a time machine that can make people travel in space and time. The time machine can make the time dilation by spinning ions around it. And that thing can allow for slow time in the craft. 

The time dilation that can be made by using a spinning ion cylinder can slow the time in the craft. And that opens the route into the entire solar system. Slowing time or time dilation makes it possible to slow time in the craft. That denies the aging of the crew. That is one way to manipulate time. 

Manipulating space can happen by trapping particles into the graphene net. Then the system puts them to spin. That spinning movement binds energy to those particles. There is the possibility to create energy styluses or energy beams that are like black hole jets. Those jets can aim the radiation to slide over the object. And that thing makes them unable to make reflection. 

If that field interaction is very accurately controlled it is possible that those things can make the layer invisible to the human eye. Another way to make that thing is to use so-called Schrödinger's state. That means. There is a particle- or particle pair there the another has a normal energy level. And another is at a very low energy level. That makes energy and reflecting radiation travel in one direction.
