So what is truth, and what is wrong about wormholes?

1) What is a wormhole?

In models, the wormhole is only a pair of superpositioned and entangled black holes. There is the possibility that the gravitational waves can start to travel between two black holes and surround them by forming an "8" shaped form. That form of the gravitational waves the shape of a lying twig is making it possible that black holes or gravitational waves at the point of the event horizons to start to oscillate.

So the wormholes are forming between superpositioned and entangled black holes. They are forming similar ways with all other superpositions. But the thing that forms the superposition between the black holes is gravitational radiation. 

The same laws that are ruling other quantum entanglements rule the wormholes. 

*The energy or information can travel only from the higher energy level to the lower energy level. 

*If both sides of the wormholes are at the same energy level that breaks the wormhole. 

*Wormhole can form only when two black holes are oscillating at the same frequency. And another black hole's energy level is lower than another one. 

2) Wormholes make the exchange of information between black holes possible. 

Wormhole or Einstein-Rosen bridge through the universe. And the wormhole is the channel that makes black holes exchange information. So researchers think that wormhole is a gravitational tornado that travels through the universe. That thing means that all coherent radiation channels can form the wormhole. But they cannot break the laws of physics. And that thing makes those weak wormholes useless in the long-distance change of information. 

That means they are not transporting cats or dogs through them. If the wormhole can make it possible to transport wave motion that doesn't mean that even hadrons can travel through that thing in one piece. And theoretical models are the beginning of real practical solutions. 

3) Forming of wormholes is connected with the speed of gravitational waves. 

So making stable wormholes between stars happens at the speed of light. If the spacecraft can reach the speed of light. In space, gravitational waves travel at the speed of light.  And only gravitational waves can form a so-called real wormhole. 

The reason why photonic tornados cannot make that thing is that they are leaking. The outcoming radiation breaks that thing. 

4) What happens inside a wormhole?

The wormhole is the tunnel through space and time. The core of that tunnel must be tight enough. The core of that channel must isolate the wormhole's internal space from the outer space. That denies the form of the crossing quantum fields. Crossing quantum fields are the thing that denies crossing the speed of light. 

If the core of the energy channel is tight enough. That makes a situation where the object rides with an energy wave. So in a wormhole, every particle and wave motion travels at the same speed. 

5) Can we sometimes travel to other stars by using a wormhole?

The question is: how big is the wormhole is. There is the possibility that wormholes are smaller than atoms. And that makes it impossible to use them in space travel. So we never can travel through that channel. 

But there is one thing that we must remember. Energy travels in a wormhole from the higher to the lower level. And if we want to benefit from wormholes in space travel we must travel to a lower-energy star than the sun. If we want to make the hypothetical journey to Alpha Centauri by using a wormhole, we must make one thing. 

We must travel first to Proxima Centauri. Theoretically, we could build a wormhole that transports information from the Sun to Proxima Centauri. The G2 spectral class star, Sun is a higher energy level than red dwarf Proxima Centauri. And then if we want to travel back we should make another wormhole near Alpha Centauri that is a higher energy level than the sun. And that makes information travel to the sun. 

6) There is a possibility that we can only transmit data through the wormhole. 

Transmitting data like photons or electromagnetic wave motion through the wormhole is easier than sending living organisms through that energy channel. There is a possibility that small wormholes are making long-distance quantum entanglement possible. 

Wormholes are a great opportunity. They can offer the possiblity to transfer black holes' energy to Earth. Or they can offer the possiblity to create safe-long distance communication. 

But can we someday travel through those wormholes? Nobody knows what happens in the future. Maybe, someday in the distant future, we can make those kinds of things. Before that, we must create theoretical models of how to create a wormhole.
