The universe is a hologram according to a new simulation study where a team of physicists propose that we may live in a holographic projection.
Initially proposed in 1997 by theoretical physicist Juan Maldacena, the theory is that the universe has gravity that comes from thin, vibrating strings. These strings are holograms where real action takes place in simpler and flatter cosmos that have no gravity.
Using simulations with complex calculations, two papers have explored Maldacena’s theory. What is most notable about the new study is it gives new life to Albert Einstein’s theory of gravity when it comes to quantum physics.
Yoshifumi Hyakutake of Ibaraki University in Japan posted two papers on the arXiv repository and explained how him and his colleagues can now provide evidence that supports the theory that the universe is a hologram. Maldacena told reporters,
“It seems to be a correct computation. The findings are an interesting way to test many ideas in quantum gravity and string theory.”
Theoretical physicist at Stanford University in California Leonard Susskind further explained the excitement behind the new discovery:
“They have numerically confirmed, perhaps for the first time, something we were fairly sure had to be true, but was still a conjecture — namely that the thermodynamics of certain black holes can be reproduced from a lower-dimensional universe.”
