Five incredible futuristic engines for hypothetical spacecraft 

The expansion of the universe and benefiting dark energy

The image of the timeline of the universe is used for modeling the antigravity or antimatter engine. That shows that the images can use for many purposes. So think that the stars and galaxies inside that bell-looking image are the particles that are turning to singularities or targets for antimatter injection. There are five incredible futuristic engines for hypothetical spacecraft. 

1) The quantum tunnel engines

Quantum tunneling causes that extremely small particle can cross the speed of light for a short period. So what if we would create nanotube-based ion motors where is no quantum fields inside those accelerating tubes. 

If the particle accelerators would point in that nanostructure. That thing can cause that exhausting gases or subatomic particles would travel backward at extremely high speed. Those particles are pushing the craft forward with the same speed when they are traveling backward. 

The speed of exhaust gas or exhaust particles is the same as the spacecraft.  And the speed of exhaust gas is the limit of the speed of spacecraft. That travels with the same speed forward what its exhaust gas is traveling backward. 

Maybe the tunneling effect doesn't break the speed of the light, but it can increase the speed of the ions of the ion rocket. And that thing makes them incredible machines. 

2) What if we can use dark energy as the power source of rocket engines? 

The fact is that if researchers could point the dark energy at some point, that thing causes the material is starting to expand. But that thing requires that the dark energy can conduct to the rocket chamber, and then that thing would create the expansion effect. 

And in this case. The dark energy would affect to material inside the combustion chamber as it affects the universe. But this thing requires that the dark energy has existed and its independent force.

3) Black holes as the rocket engine's power source.

In some scenarios in the rocket engine will create a small black hole, which radiation will push the craft forward. In this hypothetical engine, the other ray of the black hole is pushing against the closed wall and another jet will go out backward. 

The speed of those jets is extremely high. This is the thing that makes the black hole-based engine very capable. That hypothetical engine could have a very big capacity in rocket systems in the distant future. 

4) The antigravity engine

What if we can turn the black hole into a white hole? That thing would turn the gravity to repelling force, that would drive the spacecraft ahead with the speed that that black hole would accelerate the material when it pulls it inside the event horizon. 

If we are thinking about an antigravity engine, what benefits the short-living extremely small black holes for giving thrust for particles we should only take the structure, what looks like the bell. And then press the particles inside that bell-shaped structure by using the magnetic fields, which turns them into quantum-size black holes. 

Then those black holes would explode in a very short period. The nano-size black holes are erupting very shortly after they are forming. And when those black holes are erupting they could send the radiation that makes the craft moving forward. 

5) The antimatter engine

The antimatter engine would be the thing that is the most conventional of these futuristic systems. The antimatter could create at the forward of the chamber by shooting the gold layer with electrons or protons. Then those antimatter particles will react with the atoms inside that bell-looking system. 

And that thing causes the powerful punch to spacecraft. The radiation of the annihilation reaction where the entire material turns to energy can use to form those small black holes of the antigravity engine. In this process, the powerful radiation of the annihilation will pump the energy to particles. Those are turning to extremely small black holes.
