27. Natural Reality / A. Classical Physics / 2. Thermodynamics / d. Entropy
19950
|
Entropy is the only time-asymmetric law, so time may be linked to entropy [New Sci.]
|
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / a. Electrodynamics
19478
|
Light moves at a constant space-time speed, but its direction is in neither space nor time [New Sci.]
|
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / d. Quantum mechanics
19474
|
Quantum states are measured by external time, of unknown origin [New Sci.]
|
19473
|
The Schrödinger equation describes the evolution of an object's wave function in Hilbert space [New Sci.]
|
27. Natural Reality / B. Modern Physics / 5. Unified Models / b. String theory
19953
|
In string theory space-time has a grainy indivisible substructure [New Sci.]
|
19476
|
String theory needs at least 10 space-time dimensions [New Sci.]
|
19954
|
It is impossible for find a model of actuality among the innumerable models in string theory [New Sci.]
|
27. Natural Reality / C. Space / 2. Space
19947
|
Hilbert Space is an abstraction representing all possible states of a quantum system [New Sci.]
|
27. Natural Reality / C. Space / 6. Space-Time
19955
|
Space-time may be a geometrical manifestation of quantum entanglement [New Sci.]
|
19948
|
Einstein's merging of time with space has left us confused about the nature of time [New Sci.]
|
19475
|
Relativity makes time and space jointly basic; quantum theory splits them, and prioritises time [New Sci.]
|
27. Natural Reality / D. Time / 1. Nature of Time / d. Time as measure
19949
|
Quantum theory relies on a clock outside the system - but where is it located? [New Sci.]
|
27. Natural Reality / D. Time / 2. Passage of Time / g. Time's arrow
19951
|
Entropy is puzzling, so we may need to build new laws which include time directionality [New Sci.]
|
27. Natural Reality / E. Cosmology / 7. Black Holes
19477
|
General relativity predicts black holes, as former massive stars, and as galaxy centres [New Sci.]
|
19952
|
Black holes have entropy, but general relativity says they are unstructured, and lack entropy [New Sci.]
|
27. Natural Reality / E. Cosmology / 8. Dark Matter
16420
|
84.5 percent of the universe is made of dark matter [New Sci.]
|
27. Natural Reality / F. Chemistry / 1. Chemistry

|
27. Natural Reality / F. Chemistry / 3. Periodic Table
17603
|
Chemistry just needs the periodic table, and protons, electrons and neutrinos [New Sci.]
