9. Mai 2018 · The original two-dimensional space would serve as the boundary of a more expansive realm, known as the bulk space. And entanglement is what knits the bulk space into a contiguous whole.

Today the most popular candidate theory of quantum gravity among physicists is string theory. According to this idea, its eponymous strings are the fundamental constituents of matter and energy, giving rise to the myriad fundamental subatomic particles seen at particle accelerators around the world. They are even responsible for gravity—a hypotheti...
If the string theorists are correct, then space is built from quantum entanglement, and time might be as well. But what would that really mean? How can space be “made of” entanglement between objects unless those objects are themselves somewhere? How can those objects become entangled unless they experience time and change? And what kind of existen...
String theory is not the only idea that suggests spacetime is emergent. String theory has “failed to live up to [its] promise as a way to unite gravity and quantum mechanics,” says Abhay Ashtekar, a physicist at Pennsylvania State University. “The power of string theory now is in providing an extremely rich set of tools, which has been used widely ...
Modern physics is a victim of its own success. Because quantum physics and general relativity are both so phenomenally accurate, quantum gravity is needed only to describe extreme situations, when enormous masses are stuffed into unfathomably tiny spaces. Those conditions exist in only a few places in nature, such as the center of a black hole—and ...
Spacetime from Entanglement. New investigations suggest that spacetime and its geometry, responsible for gravity, emerges from the mysterious phenomenon known as quantum entanglement.
29. Okt. 2023 · The ICQFT unifies matter and spacetime (gravity) as information via spacetime-matter entanglement, which encodes complete physical predictions of the theory and leads to a compelling solution to the problem of time. We consider two particular forms of spacetime-matter entangled states and their physical consequences.
16. Nov. 2015 · Entanglement lets the measurement of one particle instantaneously determine the state of a partner particle, no matter how far away it may be — even on the other side of the Milky Way.
20. März 2024 · To experimentally realize a curved spacetime such as a black hole requires a specific relative motion between the excitations and the background medium. One-dimensional supersonic flow, the...
