Set 3: Central Ideas (Advanced)

Explanation

Answer: D

PASSAGE

The following text describes the 'Holographic Principle'. The Holographic Principle is a conjecture in string theories suggesting that the entire universe can be seen as a two-dimensional information structure 'painted' on the cosmological horizon, much like a hologram which is a 2D image that appears 3D. It implies that the volume of space refers to lower-dimensional boundary information. This principle emerged from the study of black hole thermodynamics, specifically the discovery that a black hole's entropy is proportional to its 2D surface area, not its volume.

What does the Holographic Principle suggest about the universe's information?

A. It is encoded on a 2D boundary rather than throughout the 3D volume
B. It is lost forever when it enters a black hole
C. It implies that the universe is a computer simulation
D. It is concentrated solely in the center of stars✓ Correct

Detailed Explanation

Choice A is correct. The text states: 'universe can be seen as a two-dimensional information structure' and 'volume of space refers to lower-dimensional boundary information.'

Key Evidence:

• "two-dimensional information structure"

• "proportional to its 2D surface area"

Why others are wrong: B (Related, but the principle resolves this by saying info is on the boundary), C (Interpretive leap (Simulation theory is separate)), D (Not mentioned).
