Concept of White Hole and Big Bounce mind map
Context
Carlo Rovelli
Italian physicist
Author
Popular-science books
Latest work
"White Holes: Inside the Horizon"
Source: TH
White Holes vs. Black Holes
White holes
Considered opposite of black holes
Theoretical idea
Supported by math
Like movie running in reverse
Matter in black holes
Bounces back
Forms white hole
Predicted by quantum mechanics
Alters understanding
Space and time
Quantum Bounce Theory
Transition
Black holes to white holes
Via bounce
Suggestion
Universe from white hole
Creates Big Bang-like event
Implies "big bounce" origin
Concept of Time
Rovelli's view
Time not uniform
Discovered through relativistic effects
Passes differently
For different observers
Product of
Space-time
Influenced by gravity
Subject to quantum granular aspects
Space-Time and Quantum Effects
Combination
Quantum mechanics
Gravity
Indication
Space-time might have granular aspects
Influenced by
"Time-steps"
Or atoms in space
Static entities shaping space
