Wormholes are a very special theoretical body resulting from Einstein's theory of gravity. Mostly, however, they are extremely unstable. However, according to recent physicist Luke Butcher's calculations from Cambridge University, their existence sometimes takes a long time to pass a photon from a completely different space and time in space.

The wormhole is essentially a "short connection" between two different places in time and space. On the one hand, it looks like a "classic" black hole, into which everything material from a certain minimum spatial boundary falls and can no longer come back. Unlike a black hole that eventually breaks everything inside into elementary particles, the wormhole has a hole in another space-time space. At this point, everything moves out of the interior of the body, so it is logical to call it "white hole" in a sense to the black hole "inverse" object. The combination of both objects is just called "wormhole".

In this way, two very distant points in space can be theoretically linked both in space and time. The object that passes through the wormhole does not exceed the speed of light but nevertheless transcends the distance between the starter and the target much faster than the light beam flying "normal space". However, most of the theoretically-known types of wormholes are either extremely unstable or have to use their very exotic forms of matter for their stability. However, the idea of ​​a wormhole is still very attractive because it contains the theoretical possibility of sending some particles of matter over time.

Wormhole travel and time travel are popular features in a number of sci-fi stories, but they are not very likely in reality. The instability of wormholes is great and their life span is usually incredibly small. But physicist Luke Butcher has found a solution that allows light particles to pass through the wormhole - a short light pulse. Theoretically, it would be possible to transmit a certain amount of information over time using photons.

The theoretical basis for this solution was already given in 1988 by another physicist, Kip Thorne, who found that when Casimir's energy is generated in a vacuum that is negative in this case, the wormhole can stabilize for a time, so it collapses slower. Butcher showed that in some types of Casimir's wormholes, negative energy appears automatically if the wormhole is inside long enough. Still, it is only a theoretical concept, the outcome of which can be reversed in the future by other features of wormholes that we do not know yet.

Epilogue: Luke Butcher's physics can only be praised, unlike some, they are not afraid to think over such a controversial topic. When scientists do not know the advice, they call it all theories, but some understand that there is nothing impossible in development and progress.

Prologue: the theory of relativity is also a mere theory, and thus restricts mankind in evolution, the speed of light in the vacuum will be constant, but if there is anything that is much and much faster than the speed of light, could it be the idea of ​​what you, Mr Albert Einstein ?
