Scientists go to find the nature of time and space

Some researchers have discovered the potential link between general relativity and quantum mechanics. This discovery may force physicists to rethink the nature of space and time.

Nature of

In 1915, the publication of general relativity, which described gravity as a fundamental attribute of space-time. He gave a set of equations describing the distortion of space-time related to energy and momentum

According to Einstein, gravity is not just a normal force, as what physicists discovered. Gravity can be thought of as a curvature of space-time due to the mass of objects.

Einstein's theory also explains the nature of cosmic black holes, where gravity is so great that light cannot escape it. According to relativity, gravity also deforms time, where the greater the gravitational force, the slower the time passes.

In the 1970s, two physicists and Jacob Bekenstein noted the relationship between the surface area of ​​black holes and their microscopic quantum structure. This marked the first insights into the connection between Einstein's general theory of relativity.

Less than three decades later, theoretical physicist Juan Maldacena observed another link between gravity and the quantum world. That connection leads to the creation of a model with the idea that no - time can be created or destroyed by changing entanglement between different surface areas of an object. In other words, this implies that space-time is a product of entanglement between objects.

To find out more, ChunJun Cao and Sean Carroll of the California Institute of Technology conducted a number of experiments. They want to see if they can obtain the characteristics of gravity (as known in general relativity) using a pattern in which no - time arises beyond quantum entanglement. or not? Their research has been published recently on arXiv.

Using an abstract mathematical concept called Hilbert's space, Cao and Carroll found similarities between equations that control quantum entanglement and the equations of Einstein's general theory of relativity. This supports the idea that no - time and gravity appear from entanglement.

Carroll said, the next step in the study is to determine the accuracy of the assumptions they make. He said: "One of the most obvious things is to check whether the symmetry of relativity appears in this pattern - especially the idea that physical laws do not depend on speed. Our transfer through space '.

The theory of all things

Today, almost everything we know about the physical aspects of the universe can be explained by general relativity or quantum mechanics. The theory of general relativity perfectly demonstrates its role in explaining the activity of objects on a very large scale, such as planets or galaxies. Meanwhile quantum mechanics helps us understand very small things, such as atoms and atomic molecules.

However, the two theories seem to be incompatible with each other. This has led physicists to try to find a 'universal theory' - this is the only model that can explain all, including the nature of space and time.

Because gravity and space-time are an important part of "everything" , Carroll believes that the research he and Cao have done can foster the pursuit of a harmony theory between general relativity. generalization and quantum mechanics. However, he notes that this is a challenging job.

"Our research has yet to say much about other natural forces, so we are still far from the end result," Carroll said. However, if we can find such a theory, we can answer some of the biggest questions scientists face. We can understand the true nature of dark matter, dark energy, black holes and other mysterious objects of the universe.

Currently, researchers are harnessing the capabilities of the quantum world to improve computer systems and a theory of everything can accelerate the process by revealing new insights in a still field. ambiguous.

According to researcher Carroll, in the process of theoretical physicists pursuing a theory of everything, each new study - whether effective or not - still helps us to get closer to the mysteries of the universe.
