Is The Universe a Hologram? Brian Greene on Quantum Gravity & Black Holes
Science Time・8 minutes read
Physicists propose that the universe might be a hologram, deriving from a two-dimensional field, with black holes playing a crucial role in understanding the holographic principle and the laws of physics. The holographic principle, linked to the Big Bang, suggests that our 3D reality is a projection of information existing on a 2D surface, with debates on whether information entering black holes is lost forever or affects the black hole's mass, while string theory offers a potential unification of gravity and quantum mechanics.
Insights
- Physicists propose that the universe might be a hologram, suggesting that our 3D reality stems from a 2D field, challenging traditional perceptions of space.
- Black holes play a crucial role in the holographic principle and understanding physics, connecting extreme conditions like the Big Bang to mathematical breakdowns and debates on information loss within black holes.

Recent questions
Is the universe possibly a hologram?
Yes, physicists theorize the universe may be a hologram, with everything perceived in three dimensions actually deriving from a two-dimensional field. The holographic principle suggests that our familiar 3D reality could be a projection of more fundamental information existing on a two-dimensional surface.
How are black holes related to the holographic principle?
Black holes, with their intense gravitational forces, are key to understanding the holographic principle and the laws of physics. The holographic principle is linked to the Big Bang, where extreme conditions cause mathematical breakdowns similar to those at the center of black holes.
Does information entering black holes disappear forever?
There is a debate on whether information entering black holes is lost forever or affects the black hole's mass, with many scientists believing in the latter. This debate is crucial in understanding the behavior of black holes and the fate of information within them.
What is the holographic principle?
The holographic principle suggests that our familiar 3D reality could be a projection of more fundamental information existing on a two-dimensional surface. This theory challenges traditional notions of space and time, proposing a deeper understanding of the universe's structure.
How does string theory relate to the holographic principle?
String theory naturally unifies gravity and quantum mechanics, offering a potential solution to the challenge of combining these fundamental forces in a single framework. This theory plays a significant role in understanding the holographic principle and the nature of the universe at a fundamental level.
