What Is a Wormhole?

Wormholes today!

Wormholes or Einstein-Rosan Bridges are the bridges that are full of dangers, which were put forward by Albert Einstein and Nathan Rosan in 1935 with the help of the general theory of relativity, and which, in theory, provide a short way from one region to another in space-time. However, this theory was first put forward by Ludwig Flamm in 1916.

Let us give the example that is usually given.
If a worm is traveling over an apple, it can travel through the apple rather than go around the apple, and reach its destination by a fairly short route.

Wormholes have not been observed so far. However, in theory, there is assumed information about some of its properties.

The entrances and exits of wormholes are spherical. Since it cannot be shown in three dimensions in photographs or drawings, it is described as a circle. One of these entrances and exits is a black hole and the other is a white hole. The black hole - the entrance part - draws in the objects and the objects are thrown out of the white hole - the exit - by passing through the cylindrical throat.

Travel does not seem possible due to many reasons that prevent us from setting off from wormholes that have not been observed until now, even in theory, friends.

First, as John A. Wheeler stated in 1962, wormholes connecting two different regions, the universe, will be in a rather unstable state. These shortcuts in space-time may collapse into themselves during the journey and not allow us to see the end of the journey.

But there is a substance that stabilizes wormholes, that is, keeps these shortcuts open. The name of this substance is exotic substance. Exotic matter is particles with a very high negative energy density.

Second, the high radiation capacity of wormholes. Who can afford to be exposed to high radiation while traveling?

Third, foreign bodies traveling in the throats of wormholes. Perhaps hundreds of objects will be encountered during the journey and the situation of being in contact with dangerous substances will arise. Especially considering the possibility of cyclical movement of the straits on the Einstein-Rosan bridges, the journey will become quite dangerous.

If we can find a wormhole suitable for travel and stabilize it, we can also travel in time, as Michael Marris, Kip Thorne, and Ulvi Yurtsever stated in their 1998 study. But even if we intend to go back in time, at best we can go back to when the wormhole was created.

Stay with science...
