Wormholes can connect black holes in different universes

A new study of scientists offers us a littleto escape from everyday worries and think about this - what if you can send a message to another Universe with the help of a black hole? Will it reach? And how big can we send? The assumption that black holes may be a portal to other universes is not new. This was stated by the British theoretical physicist Stephen Hawking, known for his study of black holes. Today, physicists have discovered that under certain circumstances, we can send a message through a theoretically existing wormhole that connects black holes in different universes. Wow!

This may look like a wormhole

What is a wormhole?

A wormhole or wormhole isa hypothetical feature of space-time, which is a “tunnel” in space. It is believed that wormholes can be interconnected. Thus, once in a wormhole in one part of the universe, you can exit in another.

Note that General Relativity (GR)allows the existence of such tunnels. However, in order for the wormhole to be passable, certain conditions are necessary, so for a complete understanding of wormholes we are still far away.

Wormhole Research

So, back to the research of scientists. According to the results, if we send a message through a wormhole that connects black holes in different universes, then it should be very short (measured in quantum bits or qubits). So if scientists from the universe on the other side of the black hole also decide to tell us something, it will be just bits of information.

In order to establish a connection between the twouniverses, it is necessary that both universes and related black holes have a certain form and shape. For example, passage through a wormhole is possible only if space-time has negative curvature. It does not sound very clear, so let’s explain: the curvature of space-time is a physical effect, due to the divergence or convergence of the trajectories of freely falling bodies. The curvature of space can be positive and negative. A space with positive curvature is the surface of a sphere that is equally curved at every point. A space with negative curvature can take the form of a saddle for riding, with different curvatures at different points. By the way, on our Yandex.Zen channel you can read about parallel universes.

It looks like space with negative curvature

Thanks to previous research, scientists knewtheoretical transmission of information through wormholes is similar to quantum teleportation. However, in the case of wormholes there are restrictions on the amount of information transmitted. And in quantum teleportation, information can be sent almost instantly over vast distances using quantum entangled particles, that is, particles not connected to each other, regardless of the distance that separates them.

Information can change black holes

On the image: black hole event horizon. The event horizon is the area around the black hole. If information or light falls into the event horizon, it will be impossible for them to get out of there.

In a new study, scientists examined a passable wormhole using the space-time geometry described by Albert Einstein's GTR.
The results showed that simultaneously throughonly a few bits of information could be transmitted to the wormhole. Researchers have also found that sending messages through a wormhole will alter black holes.

The fact is that the sending black hole will beincrease in mass, and the receiving black hole will decrease with each message sent. At the first message, the receiving black hole will lose about 30% of its mass, and at subsequent messages it will completely disappear. In addition, each subsequent message will be reduced in size, so that ultimately it will not contain any information.

Dizzy, isn't it? Of course, everyone understands that such wormholes, connecting universes, exist only theoretically. Nevertheless, scientists do not exclude that such objects can exist or even be created. Perhaps they can even be controlled by advanced civilizations. Do you think there are any in the vastness of the universe?
