Physicists prove wormholes exist in a theoretical achievementin California. Physicists use wormholes to study quantum gravity in the lab. To do this, they use a quantum computer to watch how wormholes move.
Physicists prove wormholes exist in a theoretical achievement as they have created a quantum experiment for the first time that enables them to examine the dynamics, or behavior, of a certain form of the theoretical wormhole.
The experiment gives scientists the chance to investigate the relationships between hypothetical wormholes and quantum physics, a prediction of what is known as quantum gravity.
A group of ideas known as "quantum gravity" aim to link gravity and quantum physics, two fundamental and well-researched descriptions of nature that appear to be inherently incompatible with one another.
Keep in mind that no real wormhole has been generated by the experiment (a rupture in space and time known as an Einstein-Rosen bridge).
Maria Spiropulu, the Shang-Yi Ch'en Professor of Physics at Caltech and the principal investigator of the U.S. Department of Energy Office of Science research program Quantum Communication Channels for Fundamental Physics (QCCFP), says:
We found a quantum system that exhibits key properties of a gravitational wormhole yet is sufficiently small to implement on today’s quantum hardware. This work constitutes a step toward a larger program of testing quantum gravity physics using a quantum computer. It does not substitute for direct probes of quantum gravity in the same way as other planned experiments that might probe quantum gravity effects in the future using quantum sensing, but it does offer a powerful testbed to exercise ideas of quantum gravity.- Maria Spiropulu
The study's first authors are Harvard University's Daniel Jafferis and Alexander Zlokapa (BS '21), a former Caltech undergraduate who began working on this issue for his bachelor's thesis with Spiropulu before switching to MIT for graduate school.
In the work, physicists describe wormhole behavior that is predicted by both quantum theory and gravity.
In spite of the fact that quantum information can be transported or sent across the device in a number of different ways, it was demonstrated that the experimental procedure is at least somewhat similar to what would occur if the information were to pass through a wormhole.
The researchers tried to accomplish this by utilizing either pulses of the opposing, positive energy or negative, repulsive energy pulses to "prop open the wormhole."
Only when the equivalent of negative energy was used did they notice the distinctive signs of a traversable wormhole, which is consistent with how wormholes are predicted to function.
Physicists prove wormholes exist in a theoretical achievement. In early December 2022, Caltech researchers shocked the scientific world when they said they had made two virtual baby wormholes in a computer.
The Caltech researchers said they were able to "build" two wormholes and send a message between them. This showed that space-time travel is possible.
